Hi, it's just because I received my summit 1/16 about a week ago and there is evidently a problem with the driveshafts who are always broken. I would like to put aluminum or steel driveshafts so they wont break anymore. I would like to know if the ones made by traxxas for the 1/16 e revo (TRA 7151 X) would fit the summit, if not, are they universal? Where can I found a kit so they won't always be broken? Thanks!!!!
