Will the DTM SP 40T spur gear fit on the DRR?

should work, i run the abc 44t spur in mine. the abc spurs are much better because they have 12 diff balls in them instead of only 8 that are in the drr stock spur. you will notice a much smoother diff.

Sweet I have both cars as of the other day when I won one off ebay.. I got a used DTM SP for 65.00 canadian including shipping.. I need all the electronics for it though:( The DTM will be my main car (the one I'll take to the local micro rs4 track!) after I get some experience from tuning and tweaking the DRR..

Nice! that the spurs gears can be interchanged.. I have only seen a 42 tooth spur for the DRR.. Quite a few pinion gears though:)

A 44 tooth spur! nice.. I bet it is pretty snappy! I know the dtm sp has a really nice diff in it.. how does drr diff compare? Can we get carbide balls for these things?
I remember when racing offroad electric cars that lapping the thrust washers would always free up and smooth out the differentials quite well.. Anyone tried this yet with the DTM or DRR?
