I don't know if this is old news but I came across these OS Glow G5 Gas Plug: GGT15 that supposed to run gasoline/oil fuel. They are not cheap ($18 per plug from Tower). They say you can't use them with nitro fuel. Anyone try these yet?
I wonder if you run a high rpm/low pitch set up it could work and really cut the cost of fuel. Also, would cut down on the amount of fuel needed per flight (like half what is needed with low nitro fuel). Interesting cause this would reduce flying weight and CG shift.
