Thanks guys!
Tomorrow I will buy a second hand, complete revo. I will sell all the nitro stuff and start making an overal design. I can check if the savage suspension is an option.
Wich center diff should I choose? The diff from the OFNA Ultra LX Comp is 17 dollar on ebay. With hardened spur. I found the right ofna spur gear on the official site. partnumber: 30110. The plastic spur is around 6 dollars.
