CH ignitions has an adapter for glow plugs and making one yourself is also easy if you can find the 1/4-32 tap
the nice part is that you don't need the massive amounts of oil found in regular glow fuel, 5% oil should be just fine. nitro can also be a very low percentage or maybe even 0%. the engine will use about twice the amount of fuel for a given amount of running time but depending on how cheap you find the methanol and oil you might find it comes out about the same as gas. over here with the high price of gas (taxes[
]) and the cheap price of bulk methanol (sold as a lacquer thinner) it costs me the same either way...another solution is to simply dilute your standard glow fuel with methanol
as for props i would say something like 14x8 or 15x6
