Dude 10s is crazy I had a 8s setup in a Jammin CRT and it was very hard on the diffs my rear ring gears lasted 5-6 charges. I would try Xray diffs I hear they are the best. If you run 10s and make your truck as light as you can. I would suggest 2 5s 4500 30c flightpowers. I have more fun with 5s or 6s setups than I did with my 8s setup it was an expensive lesson to learn. Good luck.
