Well converts I tried my 50/50 gasl/methanol with a regular flywheel magneto ignition Ryobi 31 on an APC 18x6W prop and I could see an increase in my rpms vs regular gasoline (8500 vs 8000) a gain of 400-500 rpms and my fuel economy is comparable with gasoline maybe 10% less but the gain in rpms and the smoothness on the transition response was all worthed , so I can conclude that any converted engine would bennefit from this mixture, I've noticed that different engines behave different with the fuel mixture as far as glow conversion is concern some may need nitro others don't and that because of the timing characteristics or the compresion ratios that each type of engines posses, so I woul suggest that one should try the mixture and see what results one gets and on what ever engine it was done, I am going to try and increase the compresion on my ryobi so I can run it on glow without nitro or battery power hooked at all times. Till then Happy flying and landings from your buddy down in Baja.
