Programmable microprocessor controller for brushless 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).
  • 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.
  • Span gas for the perfect fit control signal from your radio control system. < / Li>


  • 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.
