I would read up on the nitro articles here on this forum. This will help you a lot in breaking it in and getting it tuned properly. Before running your Revo I recommend going through everything. Make sure all screws are tight and all screws going into metal have Loctite. I personally get a whole new stainless steel screw set(I use RC Srewz)and replace all factory screws with them. I tear apart the whole truck. Pack the diffs with diff lube, lube the transmission, check the oil in the shocks(I usually replace the shock fluids with a higher one since I generally like a stiffer suspension)and if there are any parts I want to upgrade first I would do it. Normally I start with the servo, skidplates and RPM arms. You don't have to go to this extent but I do recommend checking at least for any leaks from your diffs and shocks. Make sure all rotating parts are rotating freely and nothing is binding and go through everything that has a screw, nut or anything that is critical. You don't want anything breaking while you're breaking in the motor.
