Electronic Speed Controllers

Hobby King 20A ESC 3A UBEC

The electronic speed controllers take the direct current from the battery and generate a three phase power supply for the brushless motors. There are four speed controllers one for each motor. They have an input signal from the flight controller which is used to set the level of output, which controls the speed of the motor.

These each have to be calibrated to your throttle signal to ensure each motors behaves the same. There are also a set of parameters that can be programmed by a programming card.
