Mabey you should take the transmission apart and see for damage. Or mabey the servo is not moving far enough to engage it. I had a problem with my Warhead EVOs reverse gear, forward worked but reverse didnt. Or mabey the cluch shoes are messed up some how. I wouldnt give her to much gas in reverse or you strip the reverse gear. (I know from experience)


My rigs: Warhead EVO, Nitro Evader ST, Evader ST and a Raze
