Hobbywing 30901001 XRotor 40A ESC - Multirotor Control Unit  [HW-30901001]

Precision ESC Tuning for Multirotor Builds

The Hobbywing XRotor 40A ESC, model number 30901001, is tuned to raise flight control and throttle precision on 550/650 class multirotors. It uses a dedicated firmware profile to give crisper throttle response compared to many community firmwares. The unit ships with practical defaults and only timing left adjustable, simplifying setup for both newcomers and experienced pilots.

Clean Signal Transmission

The twisted-pair throttle signal cable helps cut interference during signal transfer, improving flight stability. This ESC accepts throttle signal frequencies up to 621Hz, making it compatible with a wide range of flight controllers and receiver setups.

Robust Power Stage

Built with quality MOSFETs, the XRotor 40A delivers very low internal resistance while supporting sustained current draw. That combination reduces heat and helps protect other electronics in prolonged flights.

A solid choice for hobbyists who want dependable ESC performance and efficiency on medium-sized multirotor frames.
