The punch control feature on the DX3S is for nitro cars to improve throttle response. Do not use with electric. Set the radio back to 0% punch control and make sure you have no expo set on the throttle side (I use a little positive expo to soften the brakes around neutral) Use punch control of the Mamba if it has to much torque. (I use 5-10% on my 4wds,40-50% for 2wd)


As i always say if something doesn't work dig the instructions out of the garbage and read em.
