HOBBYWING Skywalker just relesed this Powerful switch mode built-in BEC (the BEC voltage outputs from the S3 connector).The throttle range of each ESC can be calibrated to be suitable for different multi-rotor flying control systems transmitters. Maximum speed: 210000 RPM (2 poles motor), 70000 RPM (6 poles motor), 35000 RPM (12 poles motor). The only non OEM 4in one ESC on the market that I have seen. LIPO(2-4S)/NIMH(5-12 cells).
