Introduction

The Spektrum™ FC6250HX flight controller is the heart of your radio control helicopter experience. As a 3-axis stability system for your flybarless helicopter, the FC6250HX can be set up and tuned using your Spektrum transmitter
as a forward programming interface. All the flight controller settings can be programmed through your transmitter. Using AS3X and SAFE technology, the FC6250HX offers self-leveling beginner modes, as well as pro-level ﬂight performance.
Add a Spektrum Smart ESC to your heli to further expand integrated features with no extra wires or sensors. When the flight controller detects a Smart ESC connection, it feeds a telemetry stream to the transmitter, putting live battery data power into your hands.
The FC6250HX can also be programmed, updated, and backed up using
the Spektrum USB Programmer and PC programmer application. Visit the SPMFC6250HX product page at HorizonHobby.com for more information.

Gain Adjustment
The main Forward Programming displays ﬂight control adjustments under Swashplate and Tailrotor.
Tip: Adjust gains per ﬂight mode by setting the Setup FM Channel: Function in the setup menu. Set the Channel Input Conﬁg in the transmitter for the selected channel to Flight Mode.
After the tail gains are fairly close, use the transmitter gyro gain function to adjust the gain for each ﬂight mode.

Cyclic P Gain Adjustment (Default 50%)
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.
Cyclic I Gain Adjustment (Default 50%)
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.
Cyclic D Gain Adjustment (Default 7%)
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.
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.
Tailrotor P Gain Adjustment (Default 85%)
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.
Tailrotor I Gain Adjustment (Default 95%)
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.
Tailrotor D Gain Adjustment (Default 10%)
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.

SAFE® Technology
Always complete test ﬂights and gain adjustments before enabling SAFE Technology features.
Before enabling the stability feature, test the operation by activating SAFE Panic Recovery function in ﬂight with the transmitter sticks centered. The model should return to within 4 degrees of level.

NOTICE: High levels of vibration can lead to attitude estimation errors. When SAFE Panic Recovery is activated, if the model is outside of 4 degrees of level, evaluate the model for vibration and, if necessary, perform the calibration step.

The SAFE Panic Recovery function is activated by setting up the following mix within the transmitter:

Mixing

To activate the SAFE Panic Recovery function, move the collective stick to the center position and press the bind button (switch I) on your transmitter.
The SAFE Stability function can be enabled within the forward programming SAFE menu. All gains, ﬂight mode setup, envelope and gain settings are avail-able within the SAFE menu. To enable or disable the stability function per ﬂight mode set the FM Channel to the appropriate channel within the Setup menu.

Calibration
The FC6250HX is calibrated at the factory. Recalibrate the unit if the panic or stability functions do not return to level or if there is a slow drift in the roll, pitch, or yaw axis:
Firmware Version 5.4 or earlier the FC6250HX must be label up and level during calibration. With v5.4 it is not necessary to calibrate the sensor when the sensor orientation is changed.
Firmware Version 5.5 or newer the calibration is performed in the selected mounting orientation with the FC6250HX side facing upward being level. When changing the mounting orientation setting in v5.5 the system will ask you to calibrate the gyro. Once the model is level select Apply to complete the calibration step.
The ﬁrmware version is shown at the bottom of the forward programming screen.

Level the model using a bubble level on the roll and pitch axis, power on and initialize the system.
Go to the System Setup menu and select Calibrate.
Select Apply.
A red ﬂashing light during calibration indicates the model is either not level or not stationary. Level the model, taking care to keep it still.
A yellow ﬂashing light during calibration indicates the calibration is proceeding normally.
After the calibration is successful, the LED ﬂashes green.

Binding with Optional Second Remote Receiver

Remove the telemetry remote cable from the BND/PRG/RX2 port.
Insert a bind plug into the BND/PRG/RX2 port.
Power ON the FC6250HX, the orange LED on the remote receiver will begin to ﬂash to indicate it is in bind mode.
Leave power connected and remove the bind plug.
Reconnect the telemetry remote cable to the BND/PRG/RX2 port and press the bind button on the telemetry remote receiver. The orange LED on the telemetry remote will ﬂash when it enters bind mode. Release the bind button.
Put your transmitter into bind mode. The Orange LED on the remotes will remain lit when the bind is successful.

Repeat the process if necessary.
