The Hacker X-Pro series consists of sensorless speed controllers specifically developed for brushless motors. All versions deliver high, stable performance while staying compact and lightweight. The switching BEC is set to 5.5 V and can operate 2–6 servos.
Starting with the X-7-Pro, you can program the speed controllers using the separately available USB Interface V2, found under the Accessories tab. Alternatively, you can program every X-Pro speed controller via the transmitter.
Thanks to their adjustable operating modes, X-Pro speed controllers suit all types of model aircraft applications, including powered aircraft, electric gliders, and helicopters.
