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 drive efficiency, and long endurance. Equipped with reverse thrust braking and linear reversed thrust braking function, it can effectively reduce the sliding distance and simulate real super short-distance landing. It has multiple protections such as input voltage abnormality protection, low-voltage battery protection, over-temperature protection, throttle signal loss protection, etc., which effectively extend the service life of the electric regulator and ensure safety and reliability. Equipped with search modes, when the aircraft lands in 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 fields 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.
