Thanks Dafni,
Its still a work in progress but I'm getting there. I took the truck to the track yesterday but we didn't have enough trucks to race. The truck handles well with the center diff and transmission. The added hardware increased the weight of the truck ~12 oz. I still need to dial in the shocks for the extra weight though.
Here are some pics of the almost finished truck. I say almost because I have no brakes yet :eek:
As always, I'm looking at my options for a better solution. I may use the center diff from the ofna pirate10. It's the same size as the revo f/r diff so I will loose some weight and lower the tranny height a bit.
