Brushless ESC with UBEC for Quadcopter Multi-axis Aircraft Release Aircraft Model1. The components are used to ensure the high quality of the ESC, in particular the excellent current resistance.2. Based on BLHeli program and optimized, the throttle linearity is excellent.3. It is optimized for multi-axis and supports launching aircraft and helicopters well.4. Direction selection is added to the programming element, supporting a special bidirectional mode.5. Many parameters of the speed controller can be set by (programming card) or remote control, and the default parameters can be restored by remote control or programming card.6. With low voltage protection, over temperature protection, multiple signal loss protection functions.7. For the warning function, the throttle is kept at the lowest throttle for a certain period of time, and the ESC will beep to recover the lost flight equipment.8. The throttle range can be set to be compatible with a variety of receivers, with a smooth and gentle feel to the speed control.
