First Flight Preparation
• Remove and inspect contents
• Begin charging the flight battery (not included)
• Install the electronics (ARF version)
• Configure the flight controller (ARF version)
• Install the flight battery in the helicopter
(once it has been fully charged)
• Program your computer transmitter
• Bind your transmitter
• Familiarize yourself with the controls
• Find a suitable area for flying
Flying Checklist
❏Always turn the transmitter on first
❏Plug the flight battery into the lead from the ESC
❏Allow the ESC to initialize and arm properly
❏Verify control directions and gyro compensations are correct
❏Fly the model
❏Land the model
❏Unplug the flight battery from the ESC
❏Always turn the transmitter off last
Low Voltage Cuto (LVC)
The ESC will continuously lower power to the motor until
complete shutdown when the battery reaches 12V under
load. This helps prevent over-discharge of the Li-Po battery.
Land immediately when the ESC activates LVC. Continuing
to fly after LVC can damage the battery, cause a crash or
both. Crash damage and battery damaged due to over-
discharge are not covered under warranty.
Repeatedly flying the helicopter until LVC activates will
damage the helicopter battery.
Disconnect and remove the Li-Po battery from the aircraft
after use to prevent trickle discharge. During storage, make
sure the battery charge does not fall below 3V per cell.
The included electronic speed controller (ESC) utilizes a
head speed governor to maintain a constant head speed
during flight. The governor will work to maintain a constant
head speed throughout maneuvers and the discharge cycle
of the flight battery.
The throttle position determines the requested head speed,
and although throttle curves are still used, they will be a
constant value; all positions of the curve are set to the same
value. The lowest position of the normal flight mode throttle
curve must be set to 0 to ensure the motor can be disabled.
The default throttle curve settings listed in the transmitter
setup tables should be acceptable to most pilots and
we recommend starting with these values. If you feel
an adjustment is necessary after a few flights, adjust
the throttle percentage for the desired flight mode. We
recommend making small changes of 5% to find your
preferred head speed.
Remember the throttle position on the transmitter is simply
requesting a specific head speed and this is not related to
the actual motor power percentage.

1. Lower the throttle.
2. Power on the transmitter.
3. Center all trims.
4. To allow the ESC to arm and to keep rotors from initiat-
ing at startup, turn on throttle hold and normal flight
mode before connecting the flight battery.
5. Attach hook material to the helicopter frame and loop
material to the battery.
6. Install the flight battery on the helicopter frame. Secure
the flight battery with a hook and loop strap. Connect
the battery cable to the ESC.
CAUTION: Make sure the flight battery, wire and
connector does not come into contact with the
motor. Failure to do so will cause the motor, ESC and
battery to overheat, resulting in a crash causing property
damage and injury.
7. Do not move the helicopter until the AR636A initializes.
The swashplate will center, indicating that the unit
is ready. The AR636A status LED will illuminate once
initialization has been completed
8. The helicopter motor will emit 5 ascending tones,
indicating the ESC is armed.
CAUTION: Always disconnect the Li-Po battery
from the ESC power lead when not flying to avoid
over-discharging the battery. Batteries discharged to a
voltage lower than the lowest approved voltage may
become damaged, resulting in loss of performance and
potential fire when batteries are charged.
Binding Procedure
1. Program your transmitter using the Transmitter Setup found in this manual.
2. Insert the bind plug in the BND/DAT port on the receiver.
3. Connect the flight battery to the ESC. The orange LED on the AR636 will begin flashing rapidly to indicate bind mode.
4. Move the throttle stick to the low throttle position in normal mode.
5. Follow the procedures of your specific transmitter to enter Bind Mode. The system will connect within a few seconds.
Once connected, the orange LED will turn off and the AR636A will start the initialization process.
6. When the initialization process is complete, the Status LED light will come on solid orange.
7. Disconnect the flight battery and remove the bind plug from the AR636A. Store the bind plug in a convenient place.
Transmitter and Receiver Binding (Bind-N-Fly®Basic)
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single
specific transmitter.You need to ‘bind’ your chosen Spektrum™DSM2/DSMX technology equipped aircraft transmitter to
the receiver for proper operation.
WARNING: You must move the throttle to the LOW/OFF position during binding. Failure to do so may cause the
rotor blades to spin and the helicopter to lift during the AR636A initialization, which could result in damage to
property and injury.
NOTICE: Remove the bind plug to prevent the system from entering bind mode the next time the power is turned on.
CAUTION: When using a Futaba®transmitter with a Spektrum™DSM2®module, you must reverse the throttle channel
If you encounter problems, obey binding instructions and refer to transmitter troubleshooting guide for other instructions.
If needed, contact the appropriate Horizon Product Support office.

Throttle Hold
Control Tests
Throttle hold is used to prevent the motor from powering on
inadvertently. For safety, turn throttle hold ON any time you
need to touch the helicopter or check the direction controls.
Throttle hold is also used to turn off the motor quickly if the
helicopter is out of control, in danger of crashing, or both.
The blades will continue to spin briefly when throttle hold is
activated. Pitch and direction control is still maintained.
CAUTION: You must complete the Tail Rotor and Cyclic tests prior to every flight. Failure to complete the tests
and ensuring the sensor corrects in the proper direction can cause the helicopter to crash, resulting in property
damage and injury.
Tail Rotor
1. Power on the transmitter.
2. Turn TH HOLD ON and put transmitter in normal mode.
3. Connect the flight battery to the ESC.
NOTICE: Do not allow the helicopter to move until the
Status LED is solid orange. The AR636A will not operate
correctly if the helicopter moves before the Status LED is
solid orange.
4. Move the rudder
stick to the right. The
pitch slider on the tail
shaft should move
toward the tail case.
If the pitch slider
moves in the oppo-
site direction, ensure
the rudder channel
reverse setting within the transmitter is set to normal.
5. Release the rudder control. Manually turn the helicopter
nose to the left. The flight controller should compensate
by moving the tail slider towards the tail case.
Cyclic and Collective Control Test
Ensure the throttle hold is ON when performing the direction control tests. Test the controls prior to each flight to
ensure the servos, linkages and parts operate correctly. If the controls do not react as shown in the illustrations below,
confirm the transmitter is programmed correctly before continuing on to the Motor test.

Cyclic
When using a flybarless flight controller, you are controlling
rotational rates while the AR636A controls the servos. You
are not directly controlling the servos with the transmitter.
It is normal for the swashplate to slowly move back to
its original position after a stick input and for the servos
to not move at the same speed as your control sticks.
1. Tilt the helicopter forward. The swashplate must
tilt backward.
2. Roll the helicopter left. The swashplate must roll right.

9EN
Motor Test
Place the helicopter outdoors on a clean, flat and level
surface (concrete or asphalt) free of obstructions. Always
stay clear of moving rotor blades.
1. Before you continue, confirm that TH HOLD is ON. The
motor will emit 5 ascending tones after the helicopter’s
ESC has armed properly.
WARNING: The motor will spin when the throttle
is increased while TH HOLD is OFF.
WARNING: Stay at least 30 feet (10 meters) away
from the helicopter when the motor is running. Do
not attempt to fly the helicopter at this time.
2. Ensure the throttle is lowered completely. Confirm
the transmitter is still set to normal flight mode. Turn
throttle hold OFF to enable throttle control. Slowly
increase the throttle until the blades begin to spin. The
main blades spin clockwise when viewing the helicopter
from the top. The tail rotor blades spin counterclockwise
when viewing the helicopter from the right-hand side.

Pre-Flight Checklist
❏Check all screws and ensure that they are tight
❏Check belt tension and ensure that it is not too tight or
too loose
❏Check main and tail blades to ensure they are not damaged
❏Check all links and make sure they move freely but do
not pop off easily
❏Check that the transmitter and flight batteries are fully
charged
❏Check all wires to ensure that they are not cut, pinched,
or chaffed and are properly secured
❏Check all wire connections
❏Check gears and make sure no teeth are missing
❏Make sure flight battery is properly secured
❏Make sure the receiver is properly secured
❏Perform a complete control test
❏Verify the flight controller is correcting in the proper directions
❏Check that servos are functioning properly
Consult local laws and ordinances before choosing a location to fly your aircraft.
Select a large, open area away from people and objects.
Your first flights should be outdoors in low-wind conditions.
Always stay at least 30 feet (10 meters) away from the
helicopter when it is flying.
The Blade Fusion 270 is intended to be flown outdoors by
experienced pilots
Panic Recovery
If you get into distress while flying in any mode, push and
hold the Panic Switch and move the control sticks to their
neutral position. SAFE®technology will immediately return
the aircraft to an upright level attitude, if the aircraft is at
a sufficient height with no obstacles in its path. Return the
collective stick to 50% and release the Panic Switch to turn
off Panic Recovery and return to the current flight mode.
NOTICE: Before releasing the panic switch, make
sure the collective stick has been returned to the 50%
position. Once the panic switch has been released, full
negative collective becomes available, which could
cause the helicopter to descend rapidly.
• This mode is intended to provide the pilot with the
confidence to continue to improve their flight skills.
• Move the collective stick to 50% and return all other
transmitter controls to neutral for the quickest recovery.
• When panic is activated and once the model has reached a
level upright attitude, the negative collective is reduced to
prevent the user from pushing the model into the ground.
Takeoff
Deliberately increase throttle and establish a hover
at least 24” (0.6 meter) high, outside of ground effect.
CAUTION: Making large inputs to the roll or pitch
controls while the helicopter is on the ground
may result in a crash.
Flying
The helicopter lifts off the ground when the rotor head
reaches a suitable speed. Establish a low-level hover to
verify proper operation of your helicopter.
First flights should be performed in normal mode and low
cyclic and rudder dual rates until you are familiar with the
flying manner of the Blade Fusion 270.
CAUTION: Always fly the helicopter with your
back to the sun and the wind to prevent loss of
flight control.
Flying the Blade Fusion 270

10
EN
Landing
Establish a low level hover. Deliberately lower the throttle
until the helicopter lands.
When the helicopter is in stunt mode:
• The rotor head speed is constant.
• The main rotor will increase negative pitch as the
throttle/collective stick is moved from the middle stick
position to the low stick position. Negative pitch allows
the helicopter to fly upside down and perform aerobatics.
Change between stunt and idle up modes in a hover with
the throttle near the hovering stick position.
WARNING: Do not use wooden main blades with
the Blade Fusion 270 or injury and/or property
damage could occur. Only use Blade Fusion 270
replacement carbon fiber main blades.
Gyro Gain Adjustment
• If the tail wags or oscillates, lower the gain on the gyro.
In the transmitter gyro menu, decrease the gyro gain
values a small amount at a time until the helicopter is
stable within a particular flight mode.
• If the tail is drifting while hovering, increase the gain on the gyro.
In the transmitter gyro menu, increase the gyro gain
values a small amount at a time until the tail starts to
wag/oscillate. Afterwards, reduce the gain until the tail
stops wagging/oscillating within a particular flight mode.
Tail Belt Tension
Belt tension that is too tight results in loss of power and causes the belt to wear more quickly. Tension that is too loose
can cause belt damage and loss of tail rotor control in flight.
To check for proper belt tension:
1. View the tail rotor drive belt through the opening at the
back of the main frame.
2. Use a hex wrench or standard screwdriver to compress the
belt through the opening.
3. Apply light pressure on the belt, compressing the belt
toward the left side of the tail boom.
4. The belt tension is correct if the compressed side of
the belt reaches approximately halfway to the opposite
side of the belt.
a. If the compressed side of the belt reaches farther
than halfway to the other side of the belt, the tension
is too loose.
b. If the compressed side of the belt does not reach
halfway to the other side of the belt, the tension is
too tight.
To adjust belt tension:
1. Loosen the two horizontal stabilizer screws.
2. Loosen the 2 screws at the back of the main frame.
3. Slide the boom forward or aft to adjust the belt tension.
4. When the belt tension is properly adjusted, tighten the
2 screws at the back of the frame.
5. Tighten the horizontal stabilizer screws.
Post-Flight Inspections and Maintenance
Ball Links
Make sure the plastic ball link holds the control ball, but is not tight (binding) on the ball. When a link
is too loose on the ball, it can separate from the ball during flight and cause a crash. Replace worn
ball links before they fail.
Cleaning Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush
or a dry lint free cloth.
Bearings Replace bearings when they become damaged.
Wiring Make sure wiring does not block moving parts. Replace damaged wiring and loose connectors.
Fasteners Make sure there are no loose screws, other fasteners or connectors. Do not over tighten metal screws
in plastic parts. Tighten screw so parts are mated together, then turn screw only 1/8th of a turn more.
Rotors Make sure there is no damage to rotor blades and other parts which move at high speed. Damage
to these parts includes cracks, burrs, chips or scratches. Replace damaged parts before flying.
Flight Controller Make sure the AR636A is securely attached to the frame. Replace the double-sided tape when
necessary. The helicopter will crash if the AR636A separates from the helicopter frame.

11 EN
The Fusion 270 default settings are appropriate for most users. We recommend flying with the default parameters before
making any adjustments.
WARNING: Always disconnect the motor wires from the ESC before performing the following steps.
After completing the adjustments, reconnect the motor wires to the ESC before attempting to fly the model.
Advanced Settings (AR636A only)
Gain Parameters
1. Cyclic P Gain Adjustment (Default 100%)
Higher gain will result in greater stability. Setting the gain
too high may result in random twitches if your model has
an excessive level of vibration. High frequency oscillations
may also occur if the gain is set too high.
Lower gain will result in less stability.Too low of a value may
result in a less stable model particularly outdoors in winds.
If you are located at a higher altitude or in a warmer climate,
higher gains may be beneficial—the opposite is true for
lower altitude or colder climates.
2. Cyclic I Gain Adjustment (Default 100%)
Higher gain will result in the model remaining still, but may
cause low frequency oscillations if increased too far.
Lower gain will result in the model drifting slowly.
If you are located at a higher altitude or in a warmer climate,
higher gains may be beneficial—the opposite is true for
lower altitude or colder climates.
3. Cyclic D Gain Adjustment (Default 100%)
Higher gain will improve the response rate of your inputs.
If the gain is raised too much, high frequency oscillations
may occur.
Lower gain will slow down the response to inputs.
4. Cyclic Response (Default 100%)
Higher cyclic response will result in a more aggressive
cyclic response.
Lower cyclic response will result in a less aggressive cyclic
response.
5. Tailrotor P Gain Adjustment (Default 100%)
Higher gain will result in greater stability. Setting the gain
too high may result in random twitches if your model has
an excessive level of vibration. High frequency oscillations
may also occur if the gain is set too high.
Lower gain may result in a decrease in stability.Too low
of a value may result in a less stable model particularly
outdoors in winds.
If you are located at a higher altitude or in a warmer climate,
higher gains may be beneficial—the opposite is true for
lower altitude or colder climates.
6. Tailrotor I Gain Adjustment (Default 100%)
Higher gain results in the tail remaining still. If the gain is
raised too far, low speed oscillations may occur.
Lower gain will result in the tail drifting in flight over time.
If you are located at a higher altitude or in a warmer climate,
higher gains may be beneficial—the opposite is true for
lower altitude or colder climates.
7. Tailrotor D Gain Adjustment (Default 100%)
Higher gain will improve the response rate to your inputs. If
raised too far, high frequency oscillations may occur.
Lower gain will slow down the response to inputs, but will
not have an effect on stability.
Telemetry Based Text Generator for Advanced Settings
Advanced parameters may be easily read in text form
when using a Spektrum™telemetry based transmitter.
Transmitters may require a firmware update to access this
function. To register and update Spektrum™ transmitters,
visit www.spektrumrc.com.
Turning On Text Gen
Access the Telemetry menu, select one of the “Empty”
Telemetry slots and scroll to select “Text Gen.” Set the
display option to active (Act). Once the Text Gen message
feature has been enabled, the transmitter will display text
based menus on the telemetry screens for adjusting PID
values and servo center points. The helicopter must be
bound and initialized for the Text Gen screen to function;
scroll from the home screen past the telemetry screen(s)
to access the Text Gen screen.
Using Text Gen
The available features and stick inputs used to manipulate
the menus are the same as the methods outlined in the
following section, but using the text based programming is
more intuitive. Refer to the transmitter manual for details
on how to utilize telemetry menus.

EN
Once you have entered Gain Adjustment Mode, you can
move the cyclic stick forward and backward to select the
gain parameter you would like to adjust. Moving the stick
backward will select the next parameter. Moving the stick
forward will select the previous parameter.
The selected gain parameter is indicated on the Flight Log
screen and by the lean of the swashplate on the roll axis.
The current gain value for the selected parameter is indicated on the Flight
Log screen and by the angle of the swashplate (forward or backward) as
shown in the table at the right.
Move the cyclic stick left or right to adjust the gain value. Moving the stick right
will increase the gain value. Moving the stick left will decrease the gain value.
It is always best to adjust one gain at a time. Make small adjustments
(5% or less) and test fly the model to evaluate the adjustments that were made.
If you would like to reset the current gain value to the default value of 100%, move and hold the rudder stick
full right for 1 second. The swash will level on the pitch axis, indicating a 100% gain setting.
Saving the Gain Adjustments
All Spektrum™Transmitters:
1. Lower the throttle stick to the lowest position and
release the sticks.
2. Activate the panic recovery function until the swash
servos move.
3. Deactivate the panic recovery function to save the gain
adjustments.
4. Reconnect the main drive motor to the ESC.Your model
is now ready for flight.
Entering Gain Adjustment Mode (AR636A only)
Adjusting the Gain Values
If you are using a Spektrum™telemetry-enabled transmitter, the gain adjustments can be viewed on the Flight Log
screen. Refer to your transmitter instructions to locate this screen. The gain parameter currently selected will flash on the
transmitter screen. If you are not using a Spektrum™telemetry-enabled transmitter, the parameter and gain values are

Servo Adjustment (AR636A only)
Your Blade Fusion 270 helicopter was setup at the factory
and test flown. The servo adjustment steps are usually only
necessary in special circumstances, such as after a crash
or if a servo or linkage is replaced.
WARNING: To ensure your safety, always
disconnect the motor wires from the ESC before
performing the following steps. After you have
completed the adjustments, reconnect the motor wires
to the ESC before attempting to fly the model.
All Spektrum™Transmitters:
1. Lower the throttle stick to the lowest position.
2. Power ON the transmitter.
3. Install the flight battery on the helicopter frame,
securing it with the hook and loop strap.
4. Connect the battery connector to the ESC.
5. Place the helicopter on a flat surface and leave it still
until the orange receiver LED glows solid, indicating
initialization is complete.
6. Hold the left stick to the bottom left corner and the
right stick to the bottom right corner as shown.
7. Activate the panic recovery function until the swash
servos move.
8. Release the sticks and deactivate the panic recovery
function. The model is now in Servo Adjustment Mode.
9. Proceed to Adjusting the Servo Neutral Position to
make any desired changes.
Adjusting the Servo Neutral Position
With the model in Servo Adjustment Mode, the control stick
and gyro inputs are disabled and the servos are held in the
neutral position. Check the position of the servo arms to
see if they are perpendicular to the servos.
• If the arms are perpendicular to the servos, no
adjustment is necessary. Exit Servo Adjustment Mode.
• If one or more servo arm is not perpendicular to the
servos, continue the servo adjustment process.
While watching the swashplate servos, apply backward
cyclic and release. One of the servos will jump, indicating
which servo is selected. Press backward cyclic and release
until the servo that needs to be adjusted is selected.
Once the servo you wish to adjust is selected, move the
cyclic stick right or left to adjust the servo neutral position
in the desired direction.
If you would like to reset the current servo to the default
neutral position, hold the rudder stick full right for 1second.
The range of adjustment is limited. If you are unable to
adjust the servo arm to be perpendicular to the servo, you
must reset the servo to the default neutral position, remove
the servo arm and place it back onto the servo as close to
perpendicular as possible. You may then adjust the servo
neutral position using the left/right cyclic stick.
Swashplate Leveling
Before saving your adjustments and exiting servo
adjustment mode, verify the swashplate is level and both
main rotor blades are at 0 degrees.
If they are not, make linkage adjustments as necessary.
Saving the Servo Adjustments
All Spektrum™Transmitters:
1. Lower the throttle stick to the lowest position and
release the sticks.
2. Activate Panic Recovery until the swash servos move.
3. Deactivate Panic Recovery to save the servo
adjustments.
4. Reconnect the main drive motor to the ESC.Your model
is now ready for flight.
All of the settings are stored internally, so your adjustments
will be maintained each time you initialize the model.

Trim Flight (AR636A only)
Entering Trim Flight Mode
1. Lower the throttle stick to the lowest position.
2. Center all trims. For the included Spektrum™ DXe
transmitter (RTF only), the trims are centered when
you hear a higher pitched beep while pressing the
trim button. Move the trim in both directions until you
hear the high-pitched beep.
3. Power ON the transmitter.
4. Install the flight battery in the helicopter.
5. Connect the battery connector to the ESC.
6. Place the helicopter on a flat surface and leave it still
until the motor beeps twice and the blue ESC LED
glows solid, indicating initialization is complete.
7. Place the helicopter where you are going to take off.
8. Move and hold the left stick to the bottom left corner
and the right stick to the top left corner as shown.
9. Activate Panic Recovery until the
swashplate rotates around once.
10. Release the sticks and deactivate panic recovery.
11. The model is ready for the trim flight.
Performing the Trim Flight
1. Slowly increase the throttle to lift the model into a
stationary hover. Make corrections as necessary to
keep the model still. Evaluation does not begin until the
throttle stick is over 50% and the sticks are centered.
Making corrections will not affect the result but a
longer flight may be necessary.
2. Keep the model stationary in a hover for a total of 30
seconds. Sliding and slow movements are okay. The
main goal is to keep the rotor disk level.
3. Once you are satisfied with the trim flight, land the model.
Exiting Trim Flight Mode
1. After landing, lower the throttle stick to the lowest position.
2. Activate Panic Recovery for 2 seconds, or until the
swashplate twitches, indicating the servo positions
and attitude values have been recorded and trim flight
mode has been exited.
Flight Test
After performing the trim flight, test-fly the model to
evaluate the leveling characteristics.
• The model should return to level flight consistently.
• During takeoff, the model should lift off with minimal
corrections.
• During a hover, the control stick should remain close to
center. Small corrections are acceptable.
If the model performs poorly or does not level properly
after the trim flight, retry the entire trim flight procedure.
If the problem persists, inspect the model for damaged
components, a bent shaft or anything that may result in
increased vibration. The trim flight may not record the
correct values due to excessive vibration, flying in wind
or the model not staying level. In these cases, shorter
trim flights may be necessary. Try the 30-second, level
trim flight without corrections mentioned above first. If
the leveling characteristics are not satisfactory, gradually
shorten the trim flights, checking for improvements until
the model performs as described.
Perform this procedure if the model is not performing well or has been recently rebuilt from a crash.
The trim flight procedure was performed during the factory test flight and only needs to be performed if you notice the
model is not returning to level consistently or if the model does not remain still during stationary pirouettes. The trim flight
is used to determine the optimal settings for SAFE®technology during flight.
The trim flight must be performed in calm conditions.

15 EN
If the helicopter is experiencing drift issues after completing the trim flight procedure located at www.bladehelis.com,
perform the following calibration. The calibration procedure may also be needed following crash repairs.
To perform the calibration procedure below, the Spektrum™AR636 receiver installed in the Blade Fusion 270 must have
the most recent firmware. Receiver firmware updates and instructions are available under “PC Firmware Updates” at
www.spektrumrc.com/technology/AS3X.aspx. The transmitter/receiver programming cable (SPMA3065) is required to
update the receiver firmware.
WARNING: Before beginning the calibration procedure, disconnect the main motor and tail motor leads to
prevent accidental motor startup during calibration.
To perform the calibration procedure:
1. Ensure the surface used for calibration is level.
2. Power on the transmitter and helicopter, allowing
them to initialize.
3. Turn Throttle Hold ON.
4. Ensure the main motor and tail motor leads
are disconnected. Set the flight mode switch to
Intermediate Mode (FM1).
5. Using a bubble level as shown below, level the
helicopter by placing a foam blade holder under the
landing skid. Use additional items, as necessary, to
build up under the landing skid until the tail boom is
level.
6. Hold the left stick to the bottom right corner, the
right stick to the upper left corner and activate the
Panic Recovery function until the LED on the receiver
flashes once.
7. Release both sticks and deactivate Panic Recovery.
8. The LED on the receiver will remain solid for
1-2minutes while the calibration takes place.
Do not move the helicopter until the calibration
is completed. If the LED begins blinking rapidly, an
error has occurred. Begin the calibration procedure
again, starting with step 1.
9. After the calibration is successfully completed,
the receiver LED will blink slowly (2 seconds on,
2seconds off).
10. Power the helicopter off.
11. Reconnect the main motor and tail motor wires.
12. Perform the trim flight procedure as shown in the
Advanced Settings Addendum available at www.
bladehelis.com.
13. During subsequent flights after the trim flight, the
helicopter should return to within 5 degrees of level
consistently.
