Ok, thx for the tips, after pushing the throttle, then trim forward, then throttle back and trim back the left track works, however the right track does nothing. Unscrewed the top. ( I cant believe they put the screws in such an annoying spot in the back), Tried it again, the left part of the box is moving, however the right side does nothing when you try it, although you get the sound.

The DMD lights go green when you go forward and red when you go back, any suggestions before I go testing for a short?

thx
