Features: SKYWALKER V2 series brushless electric speed controller with UBEC, high-performance 32-bit ArmM0 main control chip, operating at a frequency of up to 96MHz, supports a speed of up to 300000rpm (2-pole motor), high reliability. The addition of synchronous rectification drive efficiency optimization technology in electric control provides faster and more linear throttle response, strong flight stability and flexibility, lower electric control temperature rise, high driver efficiency, and long endurance. Equipped with reverse thrust braking and linear reversed thrust brake function, it can effectively reduce the glide distance and simulate real super short-distance landing. It has multiple protections such as input voltage abnormality protection, low-voltage battery protection, overheating protection, throttle signal loss protection, etc., which effectively extends the life of the electric regulator and ensures safety and reliability. Equipped with search modes, when the aircraft falls into a complex environment and is difficult to find, it can be found by using the specific prompt sound emitted by the electrically adjustable drive motor. In addition, the simple parameter setting makes it more convenient to use. It can be widely used in areas such as flight control systems for unmanned aerial vehicles, drive systems for aircraft models, motor control systems for electric vehicles, etc., providing users with stable and reliable power.
