I have the hpi big bores and hellfire shock mounts http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXLZV2&P=M on my rig, and the last time out I bent the heck out of my mounting screws. Completely killed the rear end ones. Gonna be interesting to get them out. What type and length of bolt are you guys using with this set up? I would like a bolt long enough to put a lock nut on the end of it to hold everything in place. Any info on this set up would be greatly appreciated. Thank you.
