Spektrum FC6250HX

The Spektrum FC6250HX Flight Controller is a powerful model aircraft stabilization system that features the latest AS3X® and SAFE Stabilization technology. It features a leading edge 6-axis M.E.M.S. inertial gyro, powerful and fast 32 bit ARM M4 Cortex processor and proprietary Advanced Adaptive Flight Control Algorithms.

SAFE technology allows pilots to operate within fl ight modes that automatically keep the model in a manageable attitude, constantly leveling the model when the control sticks are returned to center. Additionally, pilots can use SAFE technology to use a Panic Recovery option. All these features are set up and tuned straight from a compatible Spektrum transmitter with the Forward Programming menu.

Forward Programming allows you to setup, program, and tune the FC6250HX fl ight controller without extra hardware, devices, or computers. Pilots can make

tuning changes on the fl ight line to the swashplate, tail rotor, SAFE stability, fl ight modes and more, from a compatible Spektrum transmitter.

Visit the Spektrum™ USB Programmer and PC programmer application via SpektrumRC.com for updates and changes to the FC6250HX.

Installation

1.Mount the FC6250HX fl ight controller with the servo connector block facing either forward or aft. The side of the FC2650HX facing the main rotor disc must be parallel to the rotor disc.

2.Use the included mounting tape (SPMA3032) to mount the FC6250HX fl ight controller to the airframe.

Remote Receivers

The FC6250HX fl ight controller uses a SRXL2™ Telemetry Remote to access Forward Programming as well as other SMART features. For models larger than 360mm, connect a second SRXL2 remote to the RX1 port.

SRXL2 remotes can be connected to DATA/BIND/RX2, RX2 or RX1 ports.

Two SRXL2 telemetry remotes can be used (see diagram above).

Always ensure the remotes are connected to the transmitter before

fl ying the model. A solid orange LED on each remote receiver indicates a successful connection.

Forward Programming

The FC6250HX fl ight controller is exclusively setup, programmed, and tuned via the Forward Programming menu on a compatible aircraft Spektrum radio system (e.g., Spektrum Gen2 DX and the iX series).

Visit spektrumrc.com for an updated list of Forward Programming capable transmitters and updated transmitter fi rmware.

Before entering forward programming, lower the throttle to the full stop position.

Before exiting forward programming, lower the throttle to the full stop position.

TIP: Always exit forward programming before disconnecting the power source to ensure parameters are saved.

NOTICE: Do not connect the swash plate or tail rotor servos until the servo frequency has been confi gured. Failure to do so may result in damage to the servo and/or your model.

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.

Binding

1.Power ON the FC6250HX fl ight controller and press the bind button on each remote. The remote will begin fl ashing, indicating it is ready to bind.

2.Press the bind button on your transmitter. Lower the throttle stick to the stop position and power ON the transmitter.

Once the bind process is complete, the remote receiver LED turns solid orange, indicating the FC6250HX is ready for setup.

The FC6250HX LED will begin fl ashing green, indicating a successful bind. A red fl ashing LED indicates binding is not successful. Begin the binding procedure again.

Setup

1.In your transmitter, create a new heli setup as a Normal swash plate type. Set the Frame Rate to 11ms.

The FC6250HX requires the default new model transmitter confi guration.

All channels, other than throttle, must have Reversing set to Normal. All channels, other than throttle, must have the Subtrim set to 0.

All channels, other than throttle, must have the Travel set to 100/100.

All throttle channel settings occur in the following setup procedures within the transmitter. If you are using a throttle servo do not connect the servo until you reach the throttle setup step below.

Confi gure your desired fl ight modes, throttle curves and pitch curves per the respective manufacturer recommendations for the helicopter, ESC Engine and Transmitter. Please take note that the collective pitch range will be setup within the FC6250HX setup instructions below.

Within your transmitter enable the Transmitter Gyro function and select the“Flight Mode Switch” option. Set each fl ight mode gain to 75%.

2.In the transmitter menu, select Forward Programming.

The transmitter connects to the fl ight controller, and a menu list displays.

3.Navigate to the SetuptSwashplatetOutput Setup menu again.

4.Set the Frame Rate to the operating frequency specifi ed by your servo manufacturer.

5.Select the Type menu. Set the swashplate type to match your helicopter’s confi guration. Connect the servos shown on the transmitter and per the Flight Controller connection diagram.

Select Back, and navigate to the Direction menu.

6.Set the servo reversing to ensure the collective pitch stick moves the servos in the direction of positive collective.

Select Back to return to the previous menu.
