Ok folks I hope am posting in the right forum.

I am just completed my first slash 4x4 build and I have a problem.

For some reason my car will not go in reverse. I am using a new Traxxas 2.4ghz tx and rx and the car goes fine forward but will not go in reverse. What do you suggest? bad motor/esc/servo? please help

Almost forgot - I am running the vxl-3s bl esc and 3500kv motor setup
Thanks for your help
