I have only broken in 2 new motors.
The Traxxas Revo method (see their website for details) involved driving it on the ground, and worked fine (I guess) as our engine is fine after about 2 gallons.
Our HPI 12SS has a carbide treated sleeve and they had a different break-in process, strictly based on temperature. It involved running it AT IDLE only, until up to heat, then stopping it, with piston down (VERY IMPORTANT!!) over and over and over again, for like three or four tanks. The engine is good but I only have maybe 2 quarts on it, at the most. It's a tough tune, btw.
