- Signal frequency： 20-500Hz
- Output PWM frequency： 18KHz
- Firmware： BLheli firmware/ BLHeli Bootloader
- Specially for Multi-copter, throttle respond fast;
- Suit for throttle, which can compatible well with motor;
- The maximum refresh frequency up to 500Hz throttle signal, compatible with all flight controls;
- Use new process ultra-low resistance MOSFET with miniaturization, and all flashes are N MOS with high withstanding current;
- The copper thickness of PCB is particularly thicken, low heating, specially for small aircraft.
