ESC Physics – This screen allows you to configure (dead rail only) any physics parameters you wish to apply to the ESC output on the receiver. Normally, the input from the PT or bluetooth is passed directly to the servo 0 (ESC) output. By adjusting these parameters you can add acceleration, deceleration and braking to the output. For braking, the Protothrottle brake mode must be set to ‘pulse’. You can experiment with the PT rate for this but generally setting the rate to 0.2 seconds is recommended. Note that the Android App does not support pulse braking, only the real PT can use this feature.
