I have two E4 cars that I run
One in Stock 27T silver can which has had no problems
One in Mod 4.5 Brushless 5 or 6 cell. This car has snapped 7 UJ's in 3 meetings
Anyone have a quick fix to stop this happening?

After a year off racing electric I have found these cars very easy to drive with top results gained running the cars out of the box. Lots of rear end grip with excellent handling.
