I am stock at them moment -I went through one rear diff cup when the next one goes I'll swap to an aluminum one.

I have the linkage on a dead servo - so I can manually flip between two speeds - I put two steel idlers in. I run a robinson racing slipper with steel spur on 24/65.

Based on what I've seen now the 9XL will be plenty fast and a little cooler - I've just put 2 x 25mm fans on the motor too.

Cheers
