i have run a little more than a gallon of fuel through my rc10gt with the ae 15 engine. is my engine going to kick over soon?

somone else just told me about three if your engine is tuned right.

Depends alot on how its tuned.

I would say 3-6 gallons, some .12 and .15 engines will go all the way to 8 gallons.

i've got my engine tuned really well, doesn't overheat, blows out lots of blue smoke, yet still has a kick of power, so i am expecting a long engine life then, would that be an accurate assumption?

even if you have it a little more richer than it should be, then you should be good

Yea what he said, just keep it rich.

this question comes up alot, and varies widely.

My OS .21RZ(VO1B) in one of my buggies lasted only 2 gallons, and i was running a lil on the rich side, although racing it.

My OS CV-R in one of my NTC3's is now on its 6th gallon with no signs of wear, and i race it also.

your .21 is under more strain and stress then yer .12 it sounds like.
