Main and Remote Receiver Mounting
Use double-sided mounting tape to install the 9745
remote receiver on the left side of the frame, and the
4651T main receiver on the right side of the frame, as
shown.
Antenna Installation
The 9745 and 4651T receivers have a coaxial style
antenna. We recommend installing the antennas as
shown in the illustration to maximize signal reception.
Use mounting tape to secure the longer antennas on
the 4651T so the active elements at the end of the
coaxial cables are not mounted next to the carbon ber
frame.
NOTICE: Do not cut, kink, or modify the antenna.
Damage to the coaxial portion of an antenna will
reduce the performance of the antenna. Shortening
or cutting off the 31mm tip will reduce the range.

Activating and using the Throttle Hold (TH HOLD) function in your chosen
transmitter is required for safe setup and operation. Throttle hold only cuts power
to the motor on an electric helicopter. Pitch and direction control are maintained.
WARNING: Always engage throttle hold before approaching the
helicopter.
The blades will spin if TH HOLD is OFF. For safety, turn TH HOLD ON any time you
need to touch the helicopter or check the control directions.
Additionally, turn TH HOLD ON to cut power to the motor if the helicopter is out of
control, in danger of crashing, or both.

Setup for FC6250HX Flight Controller
Flight Controller Setup
We recommend the FC6250HX Flight controller for the Fusion 550.The FC6250HX may be programmed directly
through your transmitter or with a PC. We recommend updating to the most recent rmware to begin, use the
SPMA3065 USB interface programming cable with your PC to register and update the Flight Controller. The PC
programmer tool can be downloaded from the SPMFC6250HX product page, click on the Manuals and Support
tab. Select FC6250HX PC Programmer Download and Quickstart Guide which includes both a link to download
the software and the instructions for it’s use. This manual covers the setup using the transmitter to congure the
ight controller through Forward Programming.
1. Connect your main telemetry receiver (SPM4651T) to the BND/PRG/RX2 port, and the remote receiver
(SPM9745) to the RX1 port as shown. You will need to be able to access the BND/PRG/RX2 port later to bind the
system to your radio, so be sure to leave the wiring enough exibily to be able to access that connector.
WARNING: Always remove the pinion gear or disconnect the main drive motor from the ESC to disengage the drive system during initial setup. The main
rotor blades may turn in response to setup changes or transmitter inputs. Failure to do so could result in serious personal injury or property damage.
WARNING: The following setup information is for the Spektrum FC6250HX ight controller with the Spektrum H6350 and H6360 servos and 130A Avian ESC
from the BLH4975C combo. If you are not using this combination of components, be sure to refer to your product manuals for proper setup information.
Failure to properly set up your ight controller system may lead to an uncontrollable helicopter.

11.Select the Sub Trim menu. The swashplate servos
move to the center position. Use the sub trim
adjustments to ensure the servos are level.
Before exiting the menu, ensure the main rotor
blades are at 0° collective and the swashplate is level
in the roll and pitch axis. When the nothces on top of
the blade grips and rotor hub are aligned the blades
are at 0° collective pitch, as shown in the image.
Select Back twice to exit the SwashplateOutput
Setup menu.
12.Select the AFR menu. Set the Roll to +80, and the PItch to +80. Verify that the roll and pitch cyclic are moving in the correct direction by moving the cyclic stick.
To reverse an axis, edit the axis value and invert the sign (for example; change from a postive value to a negative value to reverse the control).
Once the directions are correct, center the collective stick on the transmitter.

13.The AFR values provided in the previous step should be a good starting point, but we recommend verifying with a digital pitch guage on your helicopter.
Place a pitch gauge on a main rotor blade, ensure the throttle stick is exactly centered and the blades are at 0°. The throttle stick needs to remain centered when
setting AFR values.
• Rotate the main blades so they are perpendicular to the frame, apply full right cyclic, and adjust the AFR value for roll until your pitch gauge reads 12.5°.
• Rotate the main blades so they are parallel to the frame. Apply full aft cyclic, and adjust the AFR value for cyclic pitch until your pitch gauge reads 12.5°.
14.Adjust the Collective AFR value to set your collective pitch range. We recommend starting with +45 and adjust the pitch range to suit your needs.
You may set it as low as +/- 10° for sport ying or as high as +/- 14° for aggressive performance. We recommend +/- 12° as a starting point. Your skill level as a
3D pilot will determine how much pitch is acceptable. Proper collective management skills are required to utilize more than +/- 12 degrees..
If you cannot get equal positive and negative values, use the differential value to adjust the endpoints. The differential value does not change the center position,
only shift the endpoints.
Remove the pitch gauge.
Select Back twice to return to the Setup menu. The swashplate setup is
complete.
15.Navigate to the TailrotorOutputSetup menu.
16.Set the Frame Rate to 560Hz.
17.Connect the tail rotor servo to the number 5 port on the FC6250HX.
18.Navigate to the Direction menu. Set the direction to reverse. Move the tail rotor
stick on the transmitter to the right. Observing from behind, the tail pitch slider
should move to the left. If not, reverse the channel direction on the FC6250HX.
Select Back to return to the previous menu.
19.Select Subtrim to center the tail rotor servo.
Select Back to return to the previous menu.
20.Select the Travel menu.
• Select Left travel. Hold the transmitter tail rotor stick full left, and adjust
travel to ensure full travel and that no binding occurs.
• Select the Right travel. Hold the transmitter tail rotor stick full right, and
adjust travel to ensure full travel and that no binding occurs.
Press Back twice to return to the Setup menu. Tailrotor setup is complete.
21.Exit Forward Programming. We recommend testing failsafe operation before proceeding. Remove the pinion gear and then run the motor. Power off the RF on
your transmitter, your motor should shut off. If it does not, rebind the system with the throttle off and test again. Reinstall the pinion gear.
22.Once your throttle failsafe test is complete, enter Forward Programming mode, and select the SetupThrottleFailsafe menu.
23.Lower the throttle stick to the full stop position, and select Capture to record the throttle failsafe position.
Select Back to return to the SetupThrottle menu.
24.Select ThrottleHover
This setting is the throttle point where your model hovers in normal mode, mainly during takeoff and landing. The ight controller applies special anti roll over
algorithms at or below the throttle setting, helping to make takeoffs and landings easier. The Stunt 1 and Stunt 2 throttle curves should be above the hover throttle
setting to ensure the roll over mitigation is disabled in ight.
During the initial setup, you can set ThrottleHover to a high value of 65% and normal offset 0%. Once the throttle setting is determined for hovering in normal
mode, set the Hover Throttle value.
Select Back to return to the Setup menu.
25.Select the Gyro SettingsOrientation Menu, and set the mounting orientation to match the FC6250HX mounting orientation on your helicopter. Once complete,
physically move the helicopter on each axis to ensure the gyros are compensating in the correct direction.
If you update your FC6250HX to the newest rmware (version 5.5 or newer) the system will ask you to perform the sensor calibration after setting the sensor
mounting orientation. Level the side of the FC6250HX that faces upwards and select Apply to complete the sensor calibration step.
With rmware version 5.4 or earlier the calibration step after changing the sensor orientation is not necessary.
Select Back twice to return to the Setup menu.
26.Select the FM Channel and select Inhibit.After initial test ights, if you would like to use individual gains for cyclic per ight mode, set the FM Channel within the
Setup menu.
27.The Gain Channel defaults to the gear channel. This is the transmitter gyro gain channel for the tail rotor. Adjust the tail gain value for each ight mode during
ight testing to maximize tail holding performance without intorducing a tail wag.
28.Press Back to exit the forward programming menu, and save the parameters.
The FC6250HX ight controller setup is complete.
29.Optional SAFE setup requires the FC6250HX is tuned for normal ight before you can set up SAFE, please refer to the FC6250HX manual for more details.

Control Tests
Motor Direction Test
Place the helicopter outdoors on a clean, at and level surface (concrete or asphalt) free of obstructions. Always stay clear of rotating parts.
1. Power on the transmitter. Make sure TH HOLD is ON and the ight mode
switch is set to NORMAL.
WARNING: The motor and rotors will spin when throttle is increased
and THHOLD is OFF.
2. Lower the throttle completely.
3. Connect the Li-Po battery to the ESC.
4. Turn TH HOLD OFF. Slowly increase the throttle until the drive train begins
to turn. The main rotor should spin clockwise when viewing the helicopter
from the top. The tail rotor should spin counterclockwise when viewing the
helicopter from the right side.
5. If the drive train does not turn with the motor or the main rotor spins
counterclockwise, turn TH HOLD ON and reverse the motor. The Avian
130A ESC can reverse the motor direction from the trasnmitter based
programming or the Avian programming box (SPMXCA200). Or, the wiring
between the ESC and the motor may be changed. To change the motor wires
disconnect the battery from the helicopter and reverse any two motor wire
connections to the ESC and repeat the motor control test.
