Crt conversion

[lincpimp]

Next project!

So I found a smoking deal on a used crt rtr with some pro hopups. Going to use a neuenergy 6s 3900 20c battery with a kb 45 8xl and a quark 125b.

Now my question is about gearing. The crt comes with buggy ratio diffs (43/13) and a 62t steel spur. Now I also have a pair of hb truggy diff gear sets, 43/10 ratio. I would also like to use a kyosho 46t plastic spur, as my pinion selection for the 6mm KB shaft are all not hardened.

So I was wondering if the hb gears will fit on the jammin diff cups and internals? I know they will fit the hyper series stuff, and the jammin parts appear to be identical. I do have enough parts to make up complete diffs with kyosho cups and hb gears/internals.

I will have to make the motor mount for the KB, and would like to finalize my gearing before I do that.
