The programmable microprocessor controller with increased supply voltage range for AC motors without sensors ( "brushless, sensorless") designed using the most modern semiconductor technology options with excellent usability features while maintaining a simple and user-friendly service. Used to control the speed of AC motors in model aircraft for the supply of NiCd / NiMH and Li-poly / Li-ion / Li-Fe. The power of the controller is electrically isolated from the control electronics to ensure high resistance to interference at high operating current and high voltage supply. The controller is equipped with a stabilizer supply for receiver and servos. For easy configuration of the controller is a special programming card FOXY Card with four-digit LED display, which is sold separately.


  • Extremely low internal resistance thanks to a new generation of power MOSFET transistors.
  • Suitable for the vast majority of AC motors.
  • For power NiCd, NiMH, Li-poly, Li-ion, Li-Fe
  • Galvanically separated above the power section using the optoelectronic component.
  • It can operate with receivers Power 4.8 to 8.4 V (4-5 Article. NiCd / NiMH 2S LiFe, LiIon, LiPo).
  • Advanced Governor Mode (constant rotor speeds) for helicopters.
  • Adjustable timing for optimally matched to the engine.
  • Adjustable Circuit PCO - disconnecting the motor at a supply voltage drop.
  • Safe switching (prevents engine starts when you turn).
  • Overload protection (when the temperature reaches 110 ° C controller performance is reduced).
  • Perimeter to prevent sparking when connecting the drive controller.
  • Automatic download of gas at the control signal is lost.
  • Continuous linear regulation of gas.
  • Advanced programming and setting the transmitter or programming card FOXY Card. < / Li>
  • Span gas for the perfect fit control signal from your radio control system.


  • Programmable brake (off - on three levels nastavuitelnými braking intensity).
  • Optional battery type (Li-Poly, LiFe or NiCd / NiMH).
  • Adjustable voltage limit for the engine shutdown, PCO - protection against excessive battery discharge. (Lithium battery: 2,8V / Art., 3.0 V / C., 3.0V / cell., 3.2 V / cell. Protection off. NiXX battery: 50% 60% / 65% of the initial value Tension.)
  • Resetting the controller settings to factory default settings.
  • Adjustable timing (advance) - to increase the efficiency and optimum adjustment of the motor (2 °, 8 °, 15 °, 22 °, 30 °)
  • Adjustable governor mode (maintaining a constant rotor speed for helicopters) or three adjustable modes with soft start for helicopters to control the engine speed via the throttle curve.
  • Adjustable rotation motor.
  • Adjustable soft start (for motors with gearboxes and helicopters) in nine stages.
  • Adjustable way to disconnect the motor at a supply voltage drop (derating or immediate disconnection).


  • Thermal overload protection: if the controller temperature reaches 110 ° C, the regulator begins to limit output power to reduce its temperature.
  • Protection against loss of control signal: the controller automatically disengages the engine when the control signal recorded a loss of gas more than 2 seconds.
  • Spark protection when connecting the drive battery: When wiring, proceed as follows - first connect the negative pole (black wire) and then the positive supply voltage (red thin wire), and finally the power conductor to the positive supply (thick red wire).

Setting regulators XR-90 and XR-120 OPTO HV

Install the controller model, attach the motor, long servo controller plug into the throttle channel of the receiver. The receiver must have its own power supply - the receiver pack or UBEC stabilizer.

Span gas

1. Turn on the transmitter and shift Throttle to "full throttle".

2. Turn on power to the controller and the receiver connect the drive battery. Wait approximately 2 seconds, the motor will beep twice (**), then the throttle fully down, the motor will beep again twice (**), which means that the controller test the extent of the control signal from the transmitter. Then, the controller checks the connected drive battery and audible alarm brake settings (one or two long tones). The controller is ready for operation.

Programming the controller parameters

The short servocable controller card, connect the programming FOXY with attached battery pack with a switch. Do not turn the card so far.


1. Turn on the transmitter, make sure that the throttle position the engine off.

2. Turn on power to the controller and the receiver connect the drive battery. Wait for normal activation - beep to indicate the regulator found that the number of articles and brake adjustment.

3. Turn off the power of the receiver.

4. Apply power program card. After 2 seconds the red LED on the card and the numbers 1 and 1 on the LED display. Now you can adjust the values \u200b\u200bof each controller functions specified in the instructions and the controller card.
