The Element 3900kV Brushless System is designed specifically for use with lightweight 1/10 scale 2WD off-road vehicles, including buggies, trucks and short course trucks. The programmable ESC and powerful 4-pole motor mount easily; after installation a simple throttle setup is all you need to get going!

  • The ESC's high level of adjustability allows for fine tuning to enhance performance even more.
  • The 4-pole, 3900kV sensorless brushless motor delivers more torque with greater efficiency, to meet the demands of today's off-road vehicles.

    ESC Programmable Features*:

  • Brake/Reverse Type - sets whether reverse is enabled or not, and how it is accessed.
  • Brake Amount - sets what percentage of available braking power is applied with full brake.
  • Reverse Amount - sets how much power will be applied in reverse, if reverse is enabled.
  • Punch/Traction Control - designed to smooth high power starts and limit punch when you don't want 100% battery power in every situation. The lower the setting the less throttle change limiting there is; for Softer acceleration or for running on low-grip surfaces, raise it to a higher setting.
  • Drag Brake - sets the amount of brake applied automatically at neutral throttle to simulate the slight braking effect of a neutral brushed motor while coasting.
  • Dead Band - lets you adjust the throttle sensitivity width at neutral. Smaller values make the controller enter forward or brake/reverse with a smaller movement of the throttle trigger for finer control.
  • Cut-Off Voltage - sets the voltage at which the ESC removes power from the motor in order to maintain the battery at a safe minimum voltage (LiPo), or to keep the radio system working reliably (NiCd/NiMH).
  • Motor Timing - allows for lowering or raising the timing advance to the motor to reduce or increase amp draw, run time, motor/battery temperature and top speed and punch.

    *ESC can be programmed manually, with the Castle Field Programming Card or through the Castle Link Software interface. (sold separately)"
