EMAX Formula Series 45A 2-5S BLHeli_32 ESC (DShot1200)

The EMAX Formula Series 45A is a single BLHeli_32 ESC, the first of EMAX's Formula32 line, for multirotors that run one ESC per motor on 2–5S LiPo. Its narrow 13.7 mm body sits neatly on the arms of racing and freestyle frames, and the 45 A rating leaves headroom for high-current motor and prop combinations.

• BLHeli_32 firmware with DShot signalling up to DShot1200
