I thought the 4.1 came supplied with the gear diff!!!!-a quick look around some searches and it looks like the RTR 4.1 does come with the gear diff and the FT version doesnt.So does that suggest that AE reckons the ball diff is better?Certainly some reports say the gear diff is definately better indoors on carpet-can anyone comment on its use outdoors on grass?cheers PC.
