Ed, does this work mainly with 2-strokes? I have mostly 4 strokes in my fleet and would love to convert them to gas but without having to add the weight of ignition. I do have a ST S75 that I think I will try your mixture with. Here's a question, seeing how the ethanol in gas is bad for our little motors. What about using Coleman white fuel? It seems to be a growing trend as it is 100% unleaded fuel. It is a little more expensive than pump gas, yet less than half the price of nitro.

Coleman fuel is just high grade, no impurities unleaded. If you are going the ignition route and running gas it probably is the way to go for quality, ease and smell. I don't want to sacrifice any weight. Therefore use glow engines with no ignition on the E85 type fuel. About 300 rpm performance loss is all and the cost per gallon with oil is $7.00 or less. With the correct tuning and the right plug I see no kneed for ignigition and battery weight. The dedicated gassers are also heavy for the power they produce. Whe you see the idle speeds and transitions of the big Tigres and Moki's I have it will convince you that ignitions are not needed with this set up.
I am working on a video, but don't want to publish it until the spreadsheets of data are all done to show the supporting info to the actual video. The oil mixtures, etc. are based on temperature of 15% nitro Cool Power fuel and used the right amount of oil to match those temperatures and protection. When I'm satified with the numbers being accurate and the video is finished as well I will publish it here in this thread.
Motors I will be using in the test range from: S2000 Super Tigre, 1.8 Moki, 1.00 NX Evolution, S-90K Super Tigre, FP40 O.S. Max, FP25 O.S. MAX, Saito 150 to name a few. I will run them on 18-20% oil mixture depending on the motor. O.S. F glow plug. Will take head and exhaust temperatures with the Cool Power and the E85 and use tach readings with various props. If anyone can think of something else they want to see in this testing by all means ask and if it is worth doing I will include them.
