Brake mode provides backward function which is Suitable for training Note Forward Reverse with Brake mode uses Double Click method to make the car go backward When you move the throttle stick from forward zone to backward zone for the first time the ESC begins to brake the motor the motor speeds down but it is still running not completely stopped so the backward action is NOT happened now When the throttle stick is moved to the backward zone again The 2 click if the motor speed is slowed down to zero i e stopped the backward action will be occurred The Double Click method can prevent mistakenly reverse when the brake function is frequently used in steering By the way in the process of braking or reverse if the throttle stick is moved to forward zone the motor will regain forward running at once 3 2 Drag Brake Force Set the amount of drag brake applied at neutral throttle to simulate the slight braking effect of a neutral brushed motor while coasting 3 3 Low Voltage Cut Off The function is mainly to prevent the lithium battery pack from over discharging When using lithium battery pack please set the suitable value for low voltage protection as your like WARNING Never use the default value Non protection for lithium battery The ESC monitors the battery s voltage at any time if the voltage is lower than the threshold the output power will be cut off 3 4 Start Mode Also called Pun
