hmm...how odd. My lil girl has had no problems handling jumps about 8ft in the air traveling for about a good 10ft. She's quadrupled just like the 1/8 truggies and she hasn't even so much as snorted.

I've never (knock on wood) bent a front or rear center drive shaft. I've broken arms, but that was due to bad landings or going darn near full tilt into the tires we have as barriers around the track.

Check your hinge pins and the little collar thingies (I know, I know...I'm so specific) that hold them in place on the camber bar (?). It could be that the collars are worn and have a little too much play in them.

This seems strange. The .5 is one of the most durable in my fleet.
