Tonight I clipped the edge of a pipe that had come apart right at the end of the straight. It sheared my a arm off and busted my shock tower. Now my servo bounces back and forth as if it can't find center. It still works fine and if it has some resistance like wheels on the ground it doesn't do it, just on the stand. Is this something I can fix or does it need service? Its a jr9100s I use the avid steering and aluminum servo arm so is this going to keep busting my servos? I know the losi buggy has no saver at all and the locked steering is pretty common, but I'd rather not replace a $140 servo more than once every few years!
