my rally shafts dont suffer to badly at all. biggest issue is that they snap fairly easily, where the hex pin goes, in a big crash or if a wheel clips something heavy n big at speed. oh - and i have the os.18 in my rally too. less resistance from smaller wheels and less leverage from shorter arms helps i guess. i still have the cup mod on the rally tho.

lots of fun with a .18 rally - try it man, mines a good bit faster than the local touring car gang.
