Best way to break in a nitro rc car?

Hey all I've just purchased a nitro rc buggy and need to break it in, what are the best and easiest ways to do it? Cheers.

It all depends on how big the engine is. Your average .18-.21 run a couple of tanks with no load, ie. tires off the ground, and at a rich setting. After that your O.K. to run it but not full throttle for to long, and don't lean it out all at once. take another three tank, leaning it out a little more with each tank. By five tanks you should be able to haul a__.. Didn't it come with a manual?
