how are bl t-maxxes?

[Gustav]

you can just make a motor mount and use the t-maxx tranny as it is,i fail to see why not,if you leave the tranny as it is you'd have to keep the mechanical brake(no bad thing) due to the one-way bearing in there.

If you don't want to fabricate anything then just drop an e-maxx transmission in there,should drop right in(e-maxx and t-maxx chassis rails are the same part so.....) .
The t-maxx has a shorter front drive shaft i think due to the brakes so you'll need a front drive shaft too if you go with an e-maxx transmission.Also e-maxx transmission outdrives are a different size too,6mm vs 5mm for the t-maxx.
