Overlander Brushless Speed Controller 40A XQ Programmable ESC (2-4s)

This series of products are developed for none-hall direct current brushless motors.They have excellent commonality,not only can be used for fixed-wing aircrafts but also for helicopters.The products have perfect function, specially 4 seconds very soft start performance which is very suitable for helicopters and the brake performance is very suitable for folding propeller aircrafts.Several parameters can be set through program card or transmitter.

Here are some highlight features of the XQ 40A Brushless ESC

Accepts up to 4 Cell Lithium Batteries

* Equipped with high-speed, small-sized, multifunctional MCU.
* Full protection feature including low-voltage protection, over-heat protection, signal lost protection, safe power on protection, and self-check functions.
* 4 seconds very soft start performance which is very suitable for helicopters.
* Excellent startup performance, great throttle linear and quick throttle response, excellent low-speed performance.
* Max speed: 240,000 RPM (2 poles), 80,000 RPM (6 poles), 40,000 RPM (12 poles).
* Individual power circuit for MCU and BEC to improve anti-interference capability.
* The parameters of ESC can be configured via program card or transmitter.
* Built-in linear BEC
* The low-voltage threshold and start-up power can be programmed quantized and precisely by program card.
* Throttle range can be configured to be compatible with different receivers.
* Three throttle curve options make helicopter control more flexible.
* Motor reverse rotation available.
