Full Metal Racing ESC 2-4s 22A FMR22A

More info »

The FMR22 ESC brings forward a ground-breaking new design utilising a Powerful 32bit ARM cortex-M3 processor running at 72Mhz, in a powerful compact package, running brand new firmware developed from the ground up.

*** INTRODUCTORY PRICE $29.95***

The lightning fast processor ensures no input pulses are missed, even at extremely high RPMs. Its bleeding edge features, including PWM frequency dithering and feed-forward compensation, combined with a sophisticated commutation algorithm, generate unmatched motor control smoothness and linearity, without sacrificing punch.

Features include:

  • Designed and manufactured in Australia, using only the highest quality components, ensuring no sacrifice in reliability.
  • Plug and play custom firmware
  • Simple solder tab for motor reverse
  • 22 Amp continuous current (with cooling). Burst: 33 (10 seconds) TBA (1 Seconds), TBA (50mS).
  • 2-4S operation.
  • True 10bit PWM resolution gives well over 1000 steps of throttle smoothness.
  • Virtually no setup time, with auto-detect multi-shot, oneshot42, oneshot125 or standard 1-2mS.
  • Advanced motor timing and auto PWM-frequency (12-36Khz) algorithm.
  • Active braking, (damped light/synchronous rectification), down to 0.1% throttle. Allowing motor free-spin at throttle-off.
  • Very high RPM, 500KERPM+.
  • Ultra fast throttle response.
  • Firmware upgradable.

 Specifications:

  • Size: 20mm x 12mm x 3.5mm
  • Weight: TBA
  • ARM 32 cortex-M3 72mhz processor

Important Notes before power up:

  • To reduce physical damage, ensure the ESC is mounted on a soft pad.
  • Ensure the ESC has good airflow
  • Ensure the cables are no thicker than 16Awg. Thick cables can stress the pads.
  • Ensure the Signal GND leads are connected
  • Ensure the Signal and Signal GNDs are twisted pair to reduce noise
  • Ensure Signal and Power polarity are correct
  • Ensure there are no cold solder joints
  • It’s always a good idea to use a smoke stopper for initial power-up
  • Thermal protection will reduce power to 70% (continous beep for 1 second)
  • If running high powered setups sufficient cooling is required due to the small size and heat dissapation abilites.
  • Do not overload ESC's with more than 22A continous current.


Important Notes after power on:

  • Ensure the ESC has been calibrated
  • Ensure the power is cycled if the comms protocol has changed
  • Ensure the ESC has been calibrated after a comms protocol change
  • Ensure min throttle is set to at least 1060+
  • Ensure the motor is spinning in the correct direction
