30A SimonK Brushless ESC with BEC

About this product

An ESC is what lets a flight controller actually steer a brushless motor, and this 30A unit is the standard match for A2212 and 2212 series motors on 3S and 4S packs. The SimonK firmware gives it the fast throttle response multirotors need, so the aircraft corrects itself quickly instead of wallowing.

The built-in 5V 2A BEC can power your flight controller and receiver directly, which saves a separate regulator on simple builds. Input leads are pre-tinned and the three motor leads come with 3.5mm bullet connectors already fitted.

Calibrate all four ESCs together through your transmitter before the first flight - the beep sequence on power-up tells you cell count and arming status. A programming card or throttle-stick menu lets you change brake, timing and low-voltage cutoff.
