Product overview
The RCOK 400A -M is an electronic speed controller for UAV brushless motor propulsion from NanChang ChangKong Technology Co., Ltd (CKESC), a company in Jiangxi focused on industrial brushless motor control systems. The company began research and development in 2008 and has developed multiple industrial ESC models. This controller has a specified range of 6~14S and a listed current rating of 400A, although that rating does not distinguish continuous operation from peak current.
The RCOK 400A -M combines an industrial control program with adaptive operating parameters. Its stated control features include an algorithm intended to support motor starting in headwinds, fast throttle response, and resistance to phase loss during abrupt throttle changes, with the aim of reducing crash risk. The controller measures 128 × 64.6 × 46.5 mm and has a black aviation aluminum alloy enclosure. These dimensions describe the controller itself, while the material specification applies to its enclosure.
