i've done this break-in on a power racing 27, 2 sts d21b's, a nova t21bf and an rb s5l2g and all ran excelent. the power racing did get an air leak in the front bearing but it was a $75 on ebay so 3 gallons was a good life for it, i never fixed the bearing so the motor is in a drawer somewhere. the 2 sts's lasted about 5 gallons but the very common sts crank snap got them, still have great pinch and run great with new cranks. the nova was a beast, second best 3 port under $200 money can buy, sold it with my 8.5 a while back. the S5 was also a beast but it took me a while to get the rb tune right, even then it was still ripping and keeping up with or spanking any motor on the track, love those rb's. so from a $75 rtr motor to a sport lever italian rb this break in has worked for me. i got the idea from an article in xrc mag about how adam drake breaks in his motors this was, even the grp's.
