I have a cheap ASP .46 that runs great on FAI fuel I brew myself. If you dig around a bit you can find castor online for under $30/gallon delivered and if you're using 100% castor oil you can mix the fuel at only 12% oil content and that is sufficient. Most speed shops sell Methanol for around $40-45 for a 5 gallon container. If that doesn't work, you can always use HEET antifreeze which is just methanol...not too cheap but you can still mix your own for less than what you pay in the hobby shop. Plus, when you skip the nitro you gain a little bit of efficiency.

Just mix by volume. For example, one part of nitromethane, two parts of oil and 7 parts of methanol would give you fuel that is 10% nitro and 20% oil. The "part" is whatever measuring device you want to use. One cup nitromethane, two cups oil and 7 cups methanol would give you 10 cups of fuel that is 10% nitro and 20% oil.

Hobby People is a Calif. company and they have a sale for every holiday. That's when you buy the fuel. Just pull up the web site for the store close to you. Sign up so you get the info in the mail in advance. Last sale I think the 20% fuel was $20.00 and the 15% was $15.00. Put your money aside and buy as much fuel as you can on there next good sale. I'm still burning fuel from last year.

It won't work in a glow engine. Ethanol is a completely different chemical with different ignition and burn characteristics. And the gasoline won't play nice with our seals and o rings. OS came out with an ethanol burning engine a few years ago just about the time E85 was getting popular. I think they were banking on ethanol becoming cheap or plentiful or methanol becoming scarce. It flopped big time because it just wasn't needed.
