Drag Brake – Drag Brake also known as coast brake or auto brake is braking power applied by the ESC anytime the ESC sees a valid neutral signal from the transmitter. The higher the value, the more drag brake is applied. You can adjust Drag Brake with the onboard QuickTune LED and button setup or via the HotWire. Onboard you have 0-13 steps of Drag Brake and through the HotWire you have 0-100.
You can also set up the Aux Drag Brake and adjust 1-10 steps of Drag Brake using a spare channel and three position switch on your radio. Very handy for Rock Crawling!
