High performance microprocessor, best compatibility with all kinds of motors, highest driving efficiency.

Anti-spark circuit eliminates sparks when the battery pack is connecting with the ESC.

Three types of start mode: Normal / Soft / Very-Soft, compatible with aircraft and helicopter.

Smooth, linear, quick and precise throttle response.

Multiple protection features: Low-voltage cut-off protection / Over-heat protection / Throttle signal loss protection.

The throttle signal is transfered through optical/electrical coupled system to avoid electromagnetic interference.

Perfect governor mode for helicopter.

Wide-opened heat-sink has the best heat dissipation effect.

The firmware of the ESC can be updated through the built-in USB adapter in the

Programmable by transmitter
