The XP series aircraft ESCs produced by Shenzhen Xingyun Technology Co., Ltd. adopt high-speed and small-sized MCU with powerful functions. They have low-voltage protection, overheating protection, loss of throttle signal protection, motor start protection, and power-on self-test. The start is smooth, and there is no obvious impact and tail swing when starting the helicopter. It has good starting performance, good throttle linearity and fast throttle response. Very good low-speed performance. The 4-second super soft start function for helicopters. The maximum supported speed is 240,000 rpm (2 poles), 80,000 rpm (6 poles) and 40,000 rpm (12 poles). MCU and BEC use different voltage regulators, which are independent of each other and improve anti-interference ability. Built-in linear BEC. The multiple parameters of the speed controller can be set by the programming card or remote control. The programming card uses a liquid crystal display, which is convenient and intuitive. The low voltage protection threshold and starting power can be quantitatively and precisely set through the programming card. The throttle travel can be set to be compatible with different receivers. Three throttle curves are available. Motor reverse can be set.
