Introduction 

The Blade ® CX2 takes the beginner-friendly flight stability of the original Blade CX and adds Spektrum 2.4GHz DSM ® radio control 

that lets you fly anywhere, anytime without ever having to worry about interference. 

Best of all, the Blade CX2 is a truly Ready-for-Anyone-to-Fly micro class electric helicopter. Its coaxial counter-rotating blades cancel 

out the rotational torque that makes hovering a conventional helicopter so difficult while providing unsurpassed stability in all other 

phases of flight too. And whether you are a first-time helicopter pilot or an experienced pilot looking for the best in coaxial 

micro helicopter performance, you’ll enjoy many of the outstanding features that have the Blade CX2 flying in no time such as 

factory installed main motors, 3-in-1 control unit with mixer, ESCs and gyro, and S60 Super Sub-Micro Servos. With the 

included 5-channel transmitter, 2-cell 800mAh Li-Po battery pack, DC charger and AC adapter, you’ll have precise control for 

hovering, forward flight and more with durations of up to 10–15 minutes per charge. 

While the Blade CX2 is nearly ready-to-fly right from the box, please take the time to read through this manual completely for tips 

on battery safety and charging, control checks, flying and more. Please also take a few minutes to watch the included Instructional 

Video CD for additional tips and to see the Blade CX2 in action.

Battery Warnings and Guidelines 

The 7.4V 800mAh 2-cell Lithium Polymer Battery Pack (EFLB0990) included with your Blade CX2 features Balance Charging 

via the included 2- to 3-Cell Lithium Polymer Balancing Charger (EFLC3110) to help ensure a safe charge every time. You 

MUST read the following safety instructions and warnings before handling, charging or using the Li-Po battery pack. 

WARNING: All instructions and warnings must be followed exactly. Mishandling of Li-Po batteries can result in fire. 

By handling, charging or using the included Li-Po battery you assume all risks associated with lithium batteries. If you do not agree 

with these conditions, return your complete Blade CX2 model in new, unused condition to the place of purchase immediately. 

• You must charge the included 7.4V 800mAh 2-cell Li-Po battery pack in a safe area away from flammable materials. 

• Do not charge the battery when installed in the helicopter. 

• Never charge the battery unattended. When charging the battery you should always remain in constant observation to monitor 

the charging process and react to potential problems that may occur. 

• After flight, the battery must be cooled to ambient temperature before charging. 

• You MUST use the included 2- to 3-Cell 7.4-11.1V Li-Po Balancing Charger ONLY. Failure to do so may result in a 

fire causing personal injury and/or property damage. DO NOT use a Ni-Cd or Ni-MH charger. 

• If at any time during the charge or discharge process the battery begins to balloon or swell, discontinue charging or 

discharging immediately. Quickly and safely disconnect the battery, then place it in a safe, open area away from flammable 

materials to observe it for at least 15 minutes. Continuing to charge or discharge a battery that has begun to balloon or swell 

can result in a fire. A battery that has ballooned or swollen even a small amount must be removed from service completely. 

• In the event of a crash, you must quickly and safely disconnect and remove the battery from the model, then place it in a safe, 

open area away from flammable materials to observe it for at least 15 minutes. 

• Store the battery at room temperature and approximately ½ charge (3.8V per cell; 7.6V for a 2-cell battery pack) for best results. 

• When transporting or temporarily storing the battery, the temperature range should be from 40–120 degrees Fahrenheit. Do not 

store the battery or model in a car or direct sunlight whenever possible. If stored in a hot car, the battery can be damaged or 

even cause a fire. 

• Do not over-discharge the battery. Discharging the battery too low can cause damage to the pack resulting in reduced 

performance and duration. Li-Po cells should not be discharged to below 3V each under load. In the case of the 2-cell 

Li-Po packs used for the Blade CX2, do not allow the battery voltage to fall below 6V during flight. 

7

The Blade CX2 3-in-1 control unit does not feature a voltage cutoff of any type, so we suggest that you be extremely 

aware of the power level of the Li-Po battery pack during flight. If at any time the helicopter begins to require more 

throttle than typical to maintain hover or flight, or has lost significant power, you must land the helicopter and power 

the motors down IMMEDIATELY to prevent over-discharge of the Li-Po battery pack. If you continue to run the motors 

after noticing a loss in power, it is possible to discharge the Li-Po battery pack too far, causing permanent damage to 

the pack. 

Over-discharge of the Li-Po battery pack can result in shortened flight times, loss of power output or failure of the pack 

entirely. 

Battery Charging 

It is important that you only charge the included 7.4V 800mAh 2-cell Li-Po Battery Pack (EFLB0990) with the included 2- to 3-Cell 

7.4-11.1V Li-Po Balancing Charger (EFLC3110). Your battery pack is equipped with a Balance Charge Lead with connector that is 

only compatible with this charger. Attempting to charge the pack using another Li-Po charger or non-Li-Po compatible charger could 

result in serious damage. Please familiarize yourself thoroughly with the warnings and guidelines before continuing. 

The included 2- to 3-Cell 7.4-11.1V Li-Po Balancing Charger will charge a near fully discharged (not over-discharged) 7.4V 800mAh 

2-cell Li-Po Battery Pack in approximately 1.2–1.5 hours. In some cases the charge time may be shorter depending on the actual 

amount of capacity left in the pack after a flight. NEVER charge the battery unattended. 

Note: The Li-Po battery pack included with your Blade CX2 will arrive partially charged. For this reason the initial charge may only 

take approximately 30–50 minutes. 

The charger requires up to 1.5 amps of 11.5- to 15-Volt DC input power that can be supplied by the included AC to 12V DC, 1.5-Amp 

Power Supply (EFLC4000) for convenient charging anywhere an AC outlet is available. 

CAUTION: NEV ,ER attempt to power the charger from an AC outlet without the use of a proper AC to DC adapter/power supply. 

Note: When using the AC to DC adapter/power supply, the charger is protected to prevent damage if the alligator clips touch. 

However, please take care to ensure that the alligator clips do not cause shorting of the battery, adapter/power supply, etc. 

by keeping them clear. 

8

The charger is equipped with two LED indicators marked RED and GREEN on the label. These LEDs indicate the following (also found 

on the label of the charger): 

• Red Flashing LED Only: 

Input power with no battery connected 

• Red and Green Solid LED: 

Battery connected and charging 

• Red Solid LED Only: 

Charge complete 

• Red and Green Flashing LED: 

Charge error 

Once you have connected the charger to a power source (Use care to ensure proper polarity when connecting the charger to the 

power source), its red LED will flash to indicate the charger has power and is ready to begin charging. Connect the Li-Po battery 

pack to the charger using the specially marked Balance Charge Lead exiting the battery pack and the connector labeled with 7.4V on 

the charger. The connector is keyed to prevent reverse polarity connection. 

Note: Do not force the connector on the Balance Charge Lead into the connector labeled 11.1V on the charger. Doing so could 

result in damage to the battery pack and charger, and could result in a fire. 

When the battery is properly connected and charging normally, the red and green LED indicators will glow solid. Once the battery 

has been fully charged, the green LED will go out, leaving just the red LED glowing solid. The battery can now be removed from the 

charger and installed into the Blade CX2 for flight. 

Charge Errors and Indications 

In the event that both the red and green LEDs flash, a charge error has occurred. Some examples of charge errors and their indications 

include: 

• Alternating flashing of the red and green LEDs will indicate that the charge process has been interrupted. If input power to the 

charger has been interrupted due to disconnection from the power source or a drop in voltage/current output from the power 

source, unplug the battery from the charger. Next, check to make sure that the input power plug from the AC to 12V DC adapter/ 

power supply is connected or that the alligator clips are firmly and properly attached to the power source. Also be sure that the 

power source is providing the proper amount of voltage and current required to the charger. 

After confirming the connections and that the power source is delivering the necessary voltage and current, re-start the charge 

process by connecting the battery pack. Continue to monitor the charge process to ensure that no further charge errors occur. 

• Simultaneous flashing of the red and green LEDs will indicate that the voltage of the Li-Po battery pack is too low to allow the 

charge process to begin. In this case the battery may have been over-discharged due to flying the model too long (For more 

information on preventing over-discharge of the Li-Po battery pack, see the guidelines section found on page 6), or that a single 

cell or even all cells in the battery pack may be damaged. 

If after several charging attempts you continue to see this charge error indication, you should remove the battery pack 

from service and replace it with a new one.

Installing the Transmitter Batteries 

Install the 4 included AA batteries in the transmitter. Check the power level of the batteries and operation of the transmitter by 

switching the power switch on (upward). The LCD screen at the top of the transmitter will indicate the power level of the batteries. If 

at any time the voltage indicated on the LCD screen falls to 4.5V or less, an alarm will sound, and it will be necessary to replace the 

batteries with new ones. 

Note: Because the LP5DSM transmitter included with the Blade CX2 is equipped with Spektrum 2.4GHz DSM technology, it 

does not require the same input voltage or current consumption as a typical 72MHz transmitter for proper operation and 

optimum performance. 

Installing the Flight Battery 

Use the included hook and loop material for mounting the Li-Po battery pack. The “hook” material is already installed on the battery 

frame stop. The included “loop” material can be installed on the end of the battery with or without the wire leads, depending on how 

you choose to install the battery and route the wire leads. 

If you choose to install the loop material on the end of the battery with the wire leads, it will be a little more difficult to install the 

battery in the model but the wire leads can be tucked neatly inside of the body. 

If you choose to install the loop material on the end of the battery without the wire leads, it will be easier to install the battery in the 

model but the power leads (red and black leads with red JST connector) will need to be placed outside of the body. 

The battery can be installed through the opening in the rear of the body. Be sure to install the end of the battery with the loop 

material first. If you have installed the loop material on the end of the battery with the wire leads, be sure that the wire leads are 

oriented to the left side of the model so that they can pass by the stop. Slide the battery into the support frame until the hook and 

loop material makes contact. 

10

Quick Tip: You can install a tape “pull tab” on the end of the battery to make it easier to remove. You can also carefully remove some 

additional material from the opening in the rear of the body. 

Center of Gravity 

Once the battery has been properly installed and secured you will need to check the helicopter’s center of gravity. If the helicopter is 

not properly balanced it can be difficult to control and constantly try to move forward or backward in hover. 

To check the center of gravity, lift the helicopter by the stabilizer flybar with the flybar positioned perpendicular to the tail section of 

the body. Make sure that the helicopter balances level. If it does not, confirm that the battery has been properly installed and reposition 

it forward or aft if necessary. 

Must Balance Level

Control Test 

Although each Blade CX2 model is test flown at the factory, it is a good idea to test the controls prior to the first flight to ensure none 

of the servos, linkages or other parts were damaged during shipping and handling. Before proceeding, disconnect both of the 

main motor plugs from the 3-in-1 control unit, making note of their direction and polarities for proper re-installation after 

the control test is complete. It is not safe to perform the control test with the main motor plugs connected to the 3-in-1 

control unit after power up. 

Turn the transmitter on first then plug the battery into the battery lead of the 3-in-1 unit. 

Position the helicopter to view it from the left-hand side. Move the elevator control stick on the transmitter forward and back to 

check elevator pitch control. When the stick is pushed forward, the rear servo should push the swashplate upward. 

12

When the stick is pulled back, the rear servo should pull the swashplate downward. 

Position the helicopter to view it from the right-hand side. Move the aileron control stick on the transmitter left and right to check 

aileron roll control. When the stick is pushed to the left, the forward servo should push the swashplate upward. 

When the stick is pushed to the right, the forward servo should pull the swashplate downward. 

13

If at any time during the test the controls do not respond properly, double-check the servo reversing switches located under the door 

on the bottom left front of the transmitter. Dip switches 1 (THR channel reversing), 6 (AIL channel reversing), and 7 (ELE channel 

reversing) should be positioned as shown to ensure proper control response. 

CAUTION:All other dip switches should also be positioned as shown to ensure proper operation. DO NOT attempt to fly your 

Blade CX2 with any of the dip switches set in positions that are not shown. 

If the controls still do not respond properly after ensuring that the servo reversing dip switch positions are correct, you may also 

check the servo connections on the receiver side of the 3-in-1 unit. These should be positioned as follows (when viewing the helicopter 

from behind): 

AIL Channel – Forward aileron servo 

ELE Channel – Rear elevator servo 

Once you have confirmed that the servo connection locations are correct, all controls should be functioning properly. If you do encounter 

any problems with your Blade CX2 responding properly to the transmitter, do not fly. 

If you have confirmed proper control operation of your Blade CX2, unplug the flight battery from the 3-in-1 unit and reconnect the 

main motor plugs to the 3-in-1 unit, taking care to keep the proper polarity and location of each as they were before the test. Use the 

label on the 3-in-1 unit for reference of the proper polarity and locations. Note that the red wire leads are positive (+) and the black 

wire leads are negative (−). 

3-in-1 Control Unit Description, Arming and Motor Control Test 

The unique 3-in-1 Control Unit installed on your Blade CX2 is a lightweight combination of 6-channel 2.4GHz DSM receiver, main 

motor mixer, main motor electronic speed controls, and piezo gyro. The 3-in-1 unit also contains a gyro gain trimmer pot, main 

motor proportional mix trimmer pot and status LED.

Remove the helicopter front body to access the 3-in-1 unit. The gain and proportional pots can be adjusted when the front body 

is removed. Note: It will not be necessary to access the 3-in-1 unit for proper arming and usual operation.

The following checklist contains the steps you must follow to ensure proper arming and operation of the 3-in-1 unit as well as 

proper motor control response: 

❏ Each time before you fly you must ALWAYS turn on the transmitter power first before connecting the flight battery to the 3-in-1 

unit. Never connect the flight battery to the 3-in-1 unit before first powering on the transmitter. 

❏Also, 

never turn off the transmitter before disconnecting the flight battery from the 3-in-1 unit first. 

❏ Both the throttle stick and throttle trim MUST be in their lowest possible position in order for the 3-in-1 unit to arm the electronic 

speed controls for the main motors. 

If this is the first test flight, or a test flight following repairs, you will also want to center the rudder, aileron and elevator trims.

❏ After confirming that the transmitter has been turned on and has an adequate level of battery power as displayed by the LCD 

screen at the top of the transmitter, it is now safe to connect the flight battery to the 3-in-1 unit. 

Note: Each time you power the transmitter on, it will enter “Bind Mode” for a few seconds, as indicated by the red blinking LED 

located under the door on the left bottom front of the transmitter. Once this LED becomes solid, the transmitter is no longer 

in bind mode. We recommend waiting to connect the flight battery to the 3-in-1 unit until after the transmitter has exited 

bind mode, otherwise the 3-in-1 unit may not arm properly or as quickly. 

❏ With battery power applied, the 3-in-1 unit status LED will blink red, and then blink green. Do not move or sway the 

helicopter once the status LED begins to blink green confirming that the initialization process and calibration of the 

gyro has begun. It is OK to move the model when the status LED is blinking red (as in the time it takes to connect the flight 

battery to the 3-in-1 unit and place the model at rest), as long as the model remains motionless when the status LED begins to 

blink green. The gyro will not calibrate correctly if the model is moved and the green LED is blinking. 

❏ When the status LED becomes solid green, the unit is armed and ready for flight. Use caution as both main motors will 

now run with throttle stick or throttle trim input. Do not advance the throttle stick or trim until you are clear of the rotor blades 

and ready to fly. 

Note: If the status LED does not become solid green, please review the following: 

• If after blinking red the status LED becomes solid red, you have a positive Radio Frequency (RF) link between the transmitter 

and receiver of the 3-in-1 unit, but the throttle stick and throttle trim may not be in their lowest possible positions. Check 

to be sure that both the throttle stick and throttle trim are in their lowest possible position and the status LED should blink 

green then become solid green indicating the unit is armed and ready for flight. Proceed to the next step of the checklist 

once the unit is armed. 

• If after blinking red the status LED continues to flash from green to red, you do not have a positive RF link between the transmitter 

and receiver of the 3-in-1 unit. First, check to be sure that the transmitter has been powered on and has an adequate 

level of battery power. If the transmitter was indeed powered on, power both the transmitter and 3-in-1 unit down, then 

follow the steps to bind the 3-in-1 unit’s receiver to the transmitter (see pages 33–34 for more information). Once you have 

confirmed that the transmitter and receiver are properly bound, the 3-in-1 unit should now arm normally.

❏ Once you have placed the helicopter in a safe area to test motor control, free from obstructions, and are clear of the rotor 

blades, you can safely begin to power up the model. 

❏ Advance the throttle stick slowly, just until the main rotor blades begin to spin. Be sure not to advance the throttle stick too far 

to keep the helicopter from lifting off the ground. Note the direction that each of the main rotor blades spins. When viewed from 

the top, the lower main rotor blade should spin clockwise and the upper main rotor blade should spin counterclockwise. 

If either rotor blade is operating in the wrong direction, unplug the battery, then simply reverse its motor plug polarity on 

the 3-in-1 unit. Note that the proper polarity is marked on the label of the 3-in-1 unit. 

❏ After confirming that the direction of rotation for both rotor blades is correct, it is best to confirm that both rotor blades respond 

properly to rudder control inputs. With both main rotor blades spinning at a low level of power, move the rudder (left-hand) stick 

all the way to the right. This should cause the speed of the upper main rotor blade to increase, and the speed of the lower main 

rotor blade to decrease. Next, move the rudder stick all the way to the left. This should cause the speed of the lower main rotor 

blade to increase and the speed of the upper main rotor blade to decrease. If both rotor blades are not responding properly to 

rudder input, simply reverse the locations of their motor plugs on the 3-in-1 unit. Note that the proper motor plug locations are 

marked on the label of the 3-in-1 unit. 

Understanding the Controls 

If you are not familiar with the controls of your Blade CX2, please take a few minutes to familiarize yourself with them before attempting 

your first flight. 

The left stick on the Mode 2 transmitter controls both throttle (climb/descend) and rudder (yaw left/right). When the left-hand stick 

and throttle trim lever are in their lowest positions, the main rotor blades will not spin. Advancing the stick upward will increase the 

speed of the main rotor blades. Increasing the speed of the main rotor blades will cause the model to climb. 

Throttle Trim 

16 

Climb 

Decreasing the speed of the main rotor blades by lowering the left-hand stick will cause the model to descend. 

Throttle Trim 

Descend 

After lifting the model off the ground, you can balance the throttle by carefully moving the left-hand stick up and down so that the 

model will hold a stationary hover without climbing or descending.

You can also use the throttle trim to adjust the throttle value for a given stick position. For example, raising the throttle trim will allow 

the model to hover at a lower throttle stick position. However, if you do raise the throttle trim, you MUST remember to lower it (and 

the throttle stick) to the lowest possible position IMMEDIATELY in the event of a crash or rotor blade strike. 

Failure to lower the throttle trim (and throttle stick) to its lowest possible position immediately in the event of a crash could result in 

damage to the main motor ESCs in the 3-in-1 unit, which may require replacement of the 

3-in-1 unit. 

Moving the left-hand stick to the left will turn (yaw) the nose of the helicopter to the left about the axis of the main shaft. This is 

accomplished by increasing the speed of the lower main rotor blade while decreasing the speed of the upper main rotor blade. 

Rudder Trim Nose Yaws Left 

Moving the stick to the right will turn (yaw) the nose of the helicopter to the to the right about the axis of the main shaft. This is 

accomplished by increasing the speed of the upper main rotor blade while decreasing the speed of the lower main rotor blade. 

Rudder Trim 

17 

Nose Yaws Right 

The rudder trim can be used to help keep the nose of the helicopter from rotating to the left or right when in hover with no rudder 

stick input. For example, if the nose of the helicopter drifts to the right when in hover, add left rudder trim until the nose stays as 

close to straight as possible. Also note that further adjustments to the rudder trim can be made using the Main Motor Proportional 

Mix Trimmer Pot. 

The right-hand stick controls both elevator (pitch fore/aft) and aileron (roll). Pushing the stick forward will pitch the nose of the 

helicopter downward, allowing the helicopter to be flown forward. 

Elevator Trim 

Helicopter Moves Forward

Pulling the stick backward will pitch the nose of the helicopter upward, allowing the helicopter to be flown backward. 

Elevator Trim 

18 

Helicopter Moves Backward 

The elevator trim can be used to help keep the helicopter from drifting forward or backward when in hover with no elevator stick 

input. For example, if the helicopter drifts forward when in hover, pull the elevator trim downward until the helicopter hovers as level 

as possible with no forward drifting. 

Moving the stick to the left will roll the helicopter to the left, allowing the helicopter to be flown to the left. 

Aileron Trim 

Helicopter Slides Left 

Moving the stick to the right will roll the helicopter to the right, allowing the helicopter to be flown to the right. 

Aileron Trim 

Helicopter Slides Right 

The aileron trim can be used to help keep the helicopter from drifting left or right when in hover with no aileron stick input. For 

example, if the helicopter drifts to the right when in hover, add left aileron trim until the helicopter hovers as level as possible with no 

drifting to the right. 

Once you have become familiar with the controls of the helicopter, you are almost ready to fly.

Choosing a Flying Area 

When you are ready for your first flight, you will want to select a large, open area that is free of people and obstructions. We 

strongly recommend an indoor area with at least 20-feet by 20-feet of floor space and no less than 8-foot ceilings. 

If you have to make your first flight (and subsequent flights) outdoors, you MUST pick a time when wind conditions are 

COMPLETELY CALM. Due to the relatively small size and low weight of the Blade CX2, even the slightest amount of wind can cause 

you to lose control, or the rotor blades to strike each other, resulting in a crash. 

Flying the Blade CX2 

Having followed the proper 3-in-1 control unit arming procedure, confirmed proper control of the servos and motors, and found a 

suitable flying area, your Blade CX2 is ready for flight. 

In addition to reviewing the flight maneuvers outlined below, we recommend that you watch the included Instructional Video CD to 

see many of these maneuvers and adjustments performed by the Blade CX2 and pilot. 

• Slowly raise the throttle stick, increasing the speed of the main rotor blades until the model begins to lift off. Do not raise the 

throttle stick too quickly as the model could climb too fast causing you to lose control or make contact with objects 

above. 

• Lift the model off the ground just a few inches and concentrate on balancing the left-hand (throttle) stick position so that the 

model holds a steady hover altitude. In some cases it may be best to make a few short “hops” to an altitude of just a few inches 

until you become familiar with the control inputs and trim settings required to maintain a steady hover and altitude. 

As you will find, the Blade CX2 requires minor throttle adjustments to maintain its altitude in hover. Remember to keep these 

throttle adjustments as minimal as possible as large adjustments could result in a loss of control and/or a possible crash. 

• While attempting to establish a low-level hover, you can also check to see if any trim adjustments are required to help keep the 

Blade CX2 from constantly drifting in various directions. If you find the helicopter constantly drifts without any directional control 

input, it will be best to land the model before making any adjustments to the trim levers. 

If the nose of the helicopter is drifting to the left or right, you will need to adjust the rudder trim. You can also adjust the 

Main Motor Proportional Mix if you experience any difficulties in trimming nose drift with the rudder trim lever only. 

If the helicopter is drifting forward or backward, you will need to adjust the elevator trim. 

If the helicopter is drifting to the left or right, you will need to adjust the aileron trim. 

Continue to make trim adjustments until the helicopter can hover at a low altitude with very little drifting and directional control 

input. If the Blade CX2 is your first helicopter model, it may be best to have the help of an experienced helicopter pilot to trim the 

model for you before making your first flight. 

• Once you have the Blade CX2 properly trimmed and maintaining a stable low-level hover, practice using the rudder, elevator and 

aileron controls to get a feel for how the helicopter responds to control inputs. Remember to keep the control inputs as minimal 

as possible to prevent over-controlling the helicopter, especially when in hover. 

• After becoming comfortable with hovering the Blade CX2 at low-levels of altitude just a few inches off the ground, you can 

transition to hovering and flying the helicopter at higher altitudes of approximately three to four feet. At these higher altitudes 

you will be able to get a feel for the flight characteristics of the Blade CX2 when it is flying out of “ground effect.” 

• If at any time during flight you feel like the helicopter is drifting out of control, simply release all of the controls except for 

throttle. You will need to use the throttle to maintain altitude, but due to the inherent stability of the coaxial counter-rotating 

blades, the Blade CX2 will simply return to a stable hover on its own if space allows. 

• Don’t be afraid to set the helicopter down on the ground quickly by lowering the throttle when approaching walls or other 

obstacles to help prevent main rotor blade strikes. Also, the optional Training Gear Set (EFLH1205) will help to further prevent 

damage to the helicopter in the event that you must make an abrupt landing to avoid walls or other obstacles. 

• In the unfortunate event of a crash or rotor blade strike, no matter how minor or major, you MUST lower both the throttle 

(left-hand) stick and throttle trim to their lowest possible position as quickly as possible to prevent damage to the ESCs of the 

3-in-1 unit. 

19

Failure to lower both the throttle stick and throttle trim to their lowest possible positions in the event of a crash could result in 

damage to the main motor ESCs in the 3-in-1 unit, which may require replacement of the 3-in-1 unit. 

Note: Crash damage is not covered under warranty. 

• It is extremely important when hovering and flying the Blade CX2 to be aware of the power level of the Li-Po battery pack. If at 

any time the helicopter begins to require more throttle than typical to maintain hover or flight, or has lost the ability to maintain 

hover or flight due to significant loss of power, you must land the helicopter and power the motors down IMMEDIATELY to prevent 

over-discharge of the Li-Po battery pack. 

If you continue to run the motors after noticing a loss in power it is possible to discharge the Li-Po battery pack too far, causing 

permanent damage to the pack. Over-discharge of the Li-Po battery pack can result in shortened flight times, loss of power 

output or failure of the pack entirely. 

Once you have gained experience and confidence in hovering the Blade CX2, you can attempt more advanced maneuvers including: 

Forward Flight Backward Flight Pirouettes 

Skidding Takeoffs Skidding Landings Spot Landings 

Main Motor Proportional Mix Trimmer Pot Description and Adjustment 

The Main Motor Proportional Mix Trimmer Pot can be found on the left side of the 3-in-1 control unit. This “proportional” trimmer pot 

adjusts the amount of mixing between the main motors allowing you to “fine-tune” the rudder trim (sub-trim) to help prevent the 

nose from drifting to the left or right when in hover. 

Main Motor 

Proportional Mix 

Trimmer Pot 

• In a stable hover, with the rudder trim centered and no rudder control input, note toward which direction the nose of the 

helicopter is trying to drift. If the nose of the helicopter is drifting to the left, you will want to increase power to the right-hand 

motor (spinning the upper main rotor blade). This is accomplished by turning the “proportional” trimmer pot clockwise. (+) 

• If the nose of the helicopter is drifting to the right in hover, you will want to increase the power to the left-hand motor (spinning 

the lower main rotor blade). This is accomplished by turning the “proportional” trimmer pot counterclockwise. (–) 

20

Note: You must always power down the 3-in-1 unit before making adjustments to the proportional mix trimmer pot. Any changes 

made to the trimmer pot will not take effect until the 3-in-1 unit is re-initialized and re-armed. 

Also, you should always center the rudder trim lever on the transmitter after making adjustments to the proportional mix trimmer pot 

on the 3-in-1 unit. 

Note: Be sure to use the proper size and type of screwdriver to carefully make adjustments to the trimmer pot. Use of the 

improper size and type of screwdriver or too much force can damage the trimmer pot. Also be sure to take your time when 

making adjustments to the proportional trimmer pot as it may only require very slight adjustment to achieve the desired 

level of performance. 

As the battery output voltage decreases throughout the flight, it may be necessary to make small adjustments to the rudder trim or 

rudder control input in order to keep the nose of the helicopter straight. These small adjustments can be made using the rudder trim 

lever or rudder control stick and do not require additional adjustments of the proportional trimmer pot. 

Gyro Gain Trimmer Pot Description and Adjustment 

The “gain” trimmer pot adjusts the gain setting value of the piezo gyro used to aid in keeping the tail of the helicopter straight/on 

heading during flight. 

Gain Trimmer Pot 

• The gain value is set too high if the tail of the helicopter twitches/bounces quickly from side to side when in hover. If this is case 

for your model, reduce the gyro gain in small increments until the tail of the helicopter no longer twitches/bounces from side to 

side in hover. 

• Turn the gyro gain trimmer pot counterclockwise (-) to decrease gyro gain. 

• The gain value is set too low when the tail of the helicopter feels “loose” during flight, requiring constant left and right rudder 

inputs to maintain heading when in hover. If this is the case for your model, increase the gyro gain in small increments until few, 

if any, left and right rudder inputs are required to maintain heading. 

• Turn the gyro gain trimmer pot clockwise (+) to increase gyro gain. 

Note: When adjusting the gyro gain trimmer pot, the changes will take effect without the need to power down and re-arm the 

3-in-1 unit. However, please exercise extreme caution when adjusting the gyro gain trimmer pot with the model armed to 

prevent personal injury or damage to the model. 

21

Upper Main Rotor Blade Tracking Adjustment 

NOTICE: Be sure to maintain a safe distance from the helicopter (approximately 10–15 feet) when tracking the Upper Main Rotor 

Blade. 

Your Blade CX2 is equipped with an adjustable linkage between the Stabilizer Flybar and Upper Main Rotor Blade. This linkage allows 

you to adjust the tracking of the upper main rotor blade for smoother and more stable flight performance. 

• You can check the upper main rotor blade tracking either on the ground or in the air at eye level. It might be a good idea to have 

an assistant on hand to help sight the blade tracking. 

• Once the main rotor blades have been brought up to speed, note whether the tips of the upper main rotor blade are tracking in 

the same plane or not. 

Tips Out Of Track — 

Adjustment Necessary 

22 

Tips In Track — 

No Adjustment Necessary 

• If the tips are not tracking in the same plane, power the helicopter down to make adjustments to the adjustable linkage. You can 

start by turning the ends of the linkage in one-half to one-full turn at a time. Power the helicopter up again and re-check the 

blade tracking. 

If the tracking has gotten better, continue to turn the ends of the linkage in one-half to one-full turn at a time until the tips are 

tracking in the same plane. 

If the tracking has gotten worse after first turning the ends of the adjustable linkage in, turn the ends of the linkage back out onehalf 

to one-full turn at a time. If the tracking then gets better, continue to turn the ends of the linkage out one-half to one-full turn at 

a time until the tips are tracking in the same plane. 

Typically, not much adjustment should be necessary to properly track the tips of the upper main rotor blade. However, due to the 

small size of the linkage ends and threaded rods it may not always be possible to achieve absolutely perfect blade tracking. Don’t 

worry as the helicopter will still perform well as long as the blade tracking is adjusted as closely as possible. 

Note: It will not be necessary to adjust the Lower Main Rotor Blade tracking as fixed links are used between the rotor blade and 

swashplate.

Channel 5 Knob Description and Function 

The transmitter included with your Blade CX2 is equipped with an optional-use “Channel 5” knob (labeled as “CH 5”) on the top right 

panel. 

This knob allows you to control function of the transmitter’s 5th channel. This channel remains unused for flying the Blade CX2, 

however, it is available for use in controlling a variety of potential optional features including actuation of an additional servo or 

certain electronic components. It allows full proportional control of the 5th channel from approximately 0–100% travel. 

The knob can be operated in either direction for control. You can use either the most clockwise (+) or most counterclockwise (-) 

position for 0 or 100% travel, and you will achieve approximately 50% travel with the knob in the middle position, pointing directly to 

the rear of the transmitter. 

0% Travel 

50% Travel 

Transmitter and 3-in-1 Control Unit Receiver Binding and Fail-Safe 

23 

100% Travel 

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific 

transmitter. If you ever find that it is necessary to replace your transmitter or the 3-in-1 control unit in your model, it will be 

necessary for you to “Bind” the new transmitter or 3-in-1 control unit receiver to your existing transmitter or receiver for proper 

operation. 

During the binding process, the smart fail-safe (SmartSafe ) positions of your system are also set. With SmartSafe, in case of loss of 

signal, the throttle will go to the preset position that was stored during the binding process and all other channels will hold their last 

position. And if the receiver (3-in-1 Control Unit) is powered on before the transmitter, all channels but throttle will go to the fail-safe 

positions that were stored during the binding process, while the throttle channel will not generate a pulse in order to prevent the 

ESC(s) from arming. 

Note: Because the SmartSafe positions are set during the binding process, it is important to set all channels to the preferred 

fail-safe positions before proceeding. In the case of the Blade CX2, we strongly recommend setting the throttle stick and 

throttle trim to their lowest positions, and the rudder, aileron and elevator channels to their neutral positions. Channel 5 

should be set to your preferred position if you have chosen to utilize it. 

The following steps outline the binding process: 

• Each time the transmitter is turned on, it enters “Bind Mode” for a few seconds. You can tell that the transmitter is in bind mode 

when you see the red LED located under the door on the bottom left front of the transmitter blink rapidly. Once the LED becomes 

solid, the transmitter is no longer in bind mode and will transmit normally. 

LED Location

Note: For safety, disconnect both main motor plugs from the 3-in-1 control unit (as shown on page 12) before proceeding. Once 

the binding process is complete and the flight battery is unplugged from the 3-in-1 unit, reconnect the main motor plugs 

to 3-in-1 unit (as noted on page 15). 

• In order to bind the 3-in-1 control unit’s receiver to the transmitter, you must first insert the Bind Plug (included with your Blade 

CX2 and replacement 3-in-1 control units) into the “BAT” opening on the receiver. Then you will need to power on the 3-in-1 

control unit by connecting the flight battery BEFORE powering the transmitter on. 

• When you connect the flight battery to the 3-in-1 unit with the bind plug inserted into the “BAT” opening on the receiver, you will 

see an orange LED blink rapidly on the receiver itself. 

• Once the orange LED on the receiver begins to blink, turn on the transmitter. The transmitter will immediately enter bind 

mode. Then, once the orange LED on the receiver and the red LED on the transmitter turn solid, the 3-in-1 unit’s receiver is 

bound to the transmitter. Now you will need to power down the 3-in-1 control unit and transmitter, and remove the bind plug 

from the receiver. 

Note: It is extremely important that you remove the bind plug from the receiver once it has been bound to the transmitter. If you 

do not remove the bind plug, the receiver will enter bind mode every time the 3-in-1 unit is powered on.

include Free Flight fuses or devices that burn producing smoke and are securely attached to the model aircraft during flight. 

Rocket motors up to a G-series size may be used, provided they remain firmly attached to the model aircraft during flight. Model 

rockets may be flown in accordance with the National Model Rocketry Safety Code; however, they may not be launched from 

model aircraft. Officially designated AMAAir Show Teams (AST) are authorized to use devices and practices as defined within the 

Air Show Advisory Committee Document. 

9. I will not operate my model aircraft while under the influence of alcohol or within eight (8) hours of having consumed alcohol. 

10. I will not operate my model aircraft while using any drug which could adversely affect my ability to safely control my model 

aircraft. 

11. Children under six (6) years old are only allowed on a flightline or in a flight area as a pilot or while under flight instruction. 

12. When and where required by rule, helmets must be properly worn and fastened. They must be OSHA, DOT, ANSI, SNELL or 

NOCSAE approved or comply with comparable standards. 

RADIO CONTROL 

1. All model flying shall be conducted in a manner to avoid over flight of unprotected people. 

2. I will have completed a successful radio equipment ground-range check before the first flight of a new or repaired model 

aircraft. 

3. I will not fly my model aircraft in the presence of spectators until I become a proficient flier, unless I am assisted by an 

experienced pilot. 

4. At all flying sites a line must be established, in front of which all flying takes place. Only personnel associated with flying the 

model aircraft are allowed at or in front of the line. In the case of airshows demonstrations straight line must be established. An 

area away from the line must be maintained for spectators. Intentional flying behind the line is prohibited. 

5. I will operate my model aircraft using only radio control frequencies currently allowed by the Federal Communications 

Commission (FCC). Only individuals properly licensed by the FCC are authorized to operate equipment on Amateur Band 

frequencies.
