New BLHeli_S (BLHeli v.16) speed controllers with hardware PWM give higher throttle resolution and support much higher motor rpm-s when compared to standard BLHeli. This is faster BB2 version of the ESC.


BLHeli_S is new major version of "industry standard" BLHeli firmware specifically ported to STM BusyBee chip. It is a good old BLHeli in its all goodness just adds the hardware PWM and faster operation. BLHeli_S ESCs can still be configured with BLHeli Suite software and 1wire passthough from flight controllers.

  • Motor speed software limited to 500k eRPM
  • Damped light always enabled
  • Sync loss protection feature
