Features: SKYWALKER V2 series brushless electric speed controller with UBEC, high performances 32-bit ArmM0 main control chip, operating at a frequency of up to 96MHz, supporting a speed up to 300000rpm (2-stage motor), high reliability. The addition of synchronous rectification drive efficiency optimization technology in electric control brings faster and more linear throttle response, strong flight stability and flexibility, lower electric control temperature rise, high driver efficiency, and long endurances. Equipped with reverse thrust braking and linear reverse thrust braking functions, it can effectively reduce the sliding distance and simulate real super short distance landing. It has multiple protections such as input voltage abnormality protections, battery low voltage protections, overheating protections, throttle signal loss protections, etc., effectively extending the service life of the electric regulator and ensuring 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 parameters setting makes it more convenient to use. It can be widely used in fields such as unmanned aerials vehicle flight control system, aircraft model drive system, electric vehicle motor control system, etc., providing users with stable and reliable power output.
