seting up a buggy

[snail speed]

Having acquired a losi 22. What im wanting to no is about seting up the car. Is there a guide for buggys. Or does the same princpuls from a touring car apply. Its mainly damping. Shock pistons and oil im wanting to no about. Thick oil with big holes in piston vs thin oil and small holes. On the losi forums there was talk about ball diffs vs gear and how one is rubish with its slipy. The purpose of what the diffs do is the same but why the handeling difference
