Nick,


That will not work very well either...

Large engines are run on gasoline for a very good reason. Cost!


Using methanol fuel will, in theory, extract more power from the engine.

This, since methanol has, at stoichiometric ratios, 24% more energy than gasoline. But it is in theory, since methanol fuel is still burning when the descending piston unmasks the exhaust port and in the gasoline engine, the burn has been completed. So only a couple of hundred RPM will be gained.

Also, the connecting-rod needle bearings are designed to run with gasoline-soluble oil at very low percentages... With methanol soluble oil (castor or synthetic), even at the customary high percentages, their life will be very significantly abbreviated.

As to cost, glow-fuel with 5% nitro will cost 7 times as much per flight as gasoline... Not 7% more - 7 times more!
It will also be consumed at a rate 2.3 times as great, so the fuel tank needs to be much larger.
