The 4-pole, 3900kV sensorless brushless motor delivers more torque with greater efficiency, to meet the demands of today’s off-road vehicles.
-
The ESC’s high level of adjustability allows for fine tuning to enhance performance even more.
- Turns your 2WD RTR model into a serious racing machine!
- Includes a 120-day limited manufacturer’s warranty.
The Element 3900kV Brushless System is designed specifically for use with lightweight 1/10 scale 2WD off-roaders, including buggies, trucks and short course vehicles. The programmable ESC and powerful 4-pole motor mount easily; after installation a simple throttle setup is all you need to get going!
- 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.
- 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.
