I just upgraded my son's Grave Digger to Traxxas TQ 2.4ghz radio system. I have everything setup. I had to reverse the steering servo. The problem is that you have to move the trigger forward twice to get braking/reverse. I'm sure it is a programming issue, but I'm not having any luck figuring it out. I have searched the forums, but I can't seem to find anything. Any help would be appreciated, thanks!
