I just picked up a used savage flux hp and i'm fairly new to this hobby. I can't get it to go in reverse, any idea what the problem might be? I tried braking and holding the trigger in the reverse position and also letting the trigger return to neutral and then moving it to the reverse position. The truck seems to be in great condition, other than that, it runs great and steers great. Hopefully i'm just overlooking something and don't have a major problem. I need reverse until i learn to control this thing better!!
