When using the Lynxmotion Quadrino Nano as a UAV flight controller (or another MultiWii based controller), the ESC’s (electronic speed controllers) used to drive the brushless motors need to be calibrated. This is to normalize the RPM output for a given input signal on all motors. ESC’s are not all equally made and reference points therefore need to be setup.
