* Please note that the BEC portion of the ESC should only be used on 2S and 3S systems. For 4S systems the BEC needs to be disabled an our dedicated UBEC should be used or a traditional receiver pack. Please click here for a diagram on how to wire up a UBEC

Features

  • Easy setting / Easy operation.
  • Safe start-up – The motor will not start regardless of the throttle position.
  • Automatic power cut-off – When the motor is stopped or when the radio signal has been lost for more the 3 seconds.
  • High rate of switching (PWM Pulse Width Modulation) 8 kHz
  • Over voltage protected. The ESC will not start if the voltage is greater then 18V (except for the OPTO versions)
  • Low voltage cut-off 3.0V/2.7V (selectable) for Lithium-ion/Lithium Polymer or 0.9V/0.7V (selectable) for Ni-Cd/Ni-Mh batteries.
  • Selectable timing modes
    • Low Timing – Providing high efficiency for 2,4 and 6 pole motors
    • High Timing – For high speed motors (6 poles or more) and outrunner motors.
  • Selectable cut offs – hard cut off or soft cut off
