What the team has found, the steel outdrives work best when used with MIP CVD's in the front of the car. The MIP CVD's don't fit as tight in the hub bearings, and give a little bit of slop there. That helps take some of the chatter out as well. When using the POM outdrives, we suggest using the HB Ver 2 universals as they fit tighter in the bearings and the combinded amoutn of slop isn't too much. It seems to be the best combo for the POM outdrives.

As far as other questions about chatter, check to make sure you have at least version 2 HB universals or MIP CVD's. The ball joint and range of motion is greater on these, so they chatter significantly less. Also, there will always be some chatter with a spool, so a little bit isn't much to be worried about. Especially in an unloaded condition like turning the car upside down.

If you guys are still concerned about chatter, hot bodies has just recently released their DCJ driveshafts which have two universal joint in them, much like designs from Losi or Xray.
