Does someone know, or is able to measure the diameter of the diff main gear (52T) for the Ultima RB5/6.
Want to know if it fits in my 3Racing Cactus, the original diff is a bit dodgy.
Bought a diff gear from the Durango (it looks very much like the original Cactus one), 52T as well. But for some reason that gear is about 1mm larger than the original so it doesn't fit in the gearbox.

This has to be the slowest reply of all time ;)
But yes, I'm interested.
