i was doing backflips off my quarterpipe and i was doing them fine until the fifth time my revo ran out of gas in mid air. Its the worst luck. anyways my whole electronics is busted up probably from all the snow. so can anyone tell me or send a link to where i can get a new opti drive and throttle sevos? Also when the revo nose dived from 15 feet it was fine but once i started driving it there was this click clack noise like there was a pebble rolling around somwhere. hmm i should take more care of the revo but i dont want to baby it, just want to bash around and have fun.
