High power 4-in-1 ESC for micro brushless racers with 20x20 mount holes. Supports 2-4S operation.


Sunrise ESCs are known for the reliability long before the BLHeli was mainstream. The new BB2 based BLH_S ESCs are no exception.

This ESC is for you if you'd like to experience what the latest hardware and software has to offer in terms of flight characteristics and performance. 32khz motor update rate together with 8khz gyro and PID operation = ultra crisp and smooth operation. The ESC is easily one of the lightest 4S solutions currently on market - the majority of the weight is saved from the cables, but also the weight of the PCB and components per single ESC is at the lower side of ESCs currently available.
