DESC210 Kit Diff Issue

[iang454]

Hi Guy's

My son raced at RHR this weekend and used a brand new DESC210 (kit) in MM4 configuration during the 3 finals.
In the last final it threw a drive shaft and got a DNF.
After looking a few chaps said is it the kit ball diff?
They then said it wasn't the first time they had seen that.

Any idea's?

The other chassis was in RM3 spec with an RTR Gear Diff and we've raced it for 6 months with no issues.

Both cars were set up with the same cambers - toes - ride heights etc

The Ball diff does measure 3 mm total width smaller than the gear diff.

Cheers Ian
