bought the summit in august 2011 driven it maybe 10 hours at the most before left steering servo stopped working. i replaced it with a new one that traxxas sent me and have driven it no more than 3 hours since. then i was using it again yesterday when it was steering very slowly and when i turned left it wouldnt turn all the way left, but it was still turning all the way to the right. i looked and both servos were both the same temperature but still quite hot to touch. both batteries were fully charged, diffs were unlocked. has anyone had this problem before or does anyone know what may be causing this problem? id appreciate any help.
