I used to burn up the whole fuel until plane gets a dead stick with my high wing trainer, that was my old practice, but in here specially with P51 Mustang, I can't do that it's a pretty good risk. So I ain't gonna do that. How about %age of Nitro, does nitro wear out the engine's life span or not?
Nitro equates to heat in an engine, so it helps in breakin, so by that account yes it helps the longevity of the engine....but once you get higher than about a .15 %5-10 should be fine.....the smaller engines are often softer metals and only run for minutes, and often by the time it hits the ground its cooled down anyway..depends on whether its a racer or a floater...Rog
