i have a thunder tiger 2000 trainer with an os .46, a raptor f22 with a small glow trainer, a p51 40 size with a .60nx evo. the fuel is almost $30 a gallon. for which most seems to exit the muffler. My next project is going to be a top flight p51 giant rtc and the os 55 gas looks real good once you get over the sticker shock. but will it have the power? and wont it pay for itself in fuel cost?
I have an OS LA .46 that runs fine on cheap 80/20 zero-nitro FAI fuel I mix myself. Most people are using far more nitro than the engines actually require. I'm just saying...
With the zero-nitro, I see about 30% better fuel economy than a 7% or 15% nitro mix.
