Dhal22,
All you have to look for is FAI fuel. That is composed of straight Castor and Methonal only.

0% nitro, 20% castor fuel is "FAI" fuel. I think that Cooper Fuels sells it, and maybe some of the other manufacturers as well. Problem is, some of these other manufacturers, like Morgan for instance, call their 0% nitro fuel FAI even though it does not contain 20% castor, so be carefull what you buy. FAI fuel would be easy to make yourself. Just add 1 quart (32 oz) of AA castor oil, available at most hobby shops, to a gallon of methanol.

There are a number of fuel manufacturers in America that make true FAI fuel (Sig, Powermaster, Fox etc) or something very similar but as hauckf said, Morgan definitely isn't one of them even though they call it FAI fuel, avoid it like the plague . The problem is that most shops won't have it because of the limited demand. Mixing it yourself is by far the best way to go once you've found a supplier for both the methanol and castor.

David,
We make 20% castor/ 0% and 5% nitro fuel. We don't sell much of it due to low demand. I will be at the Perry Georgia show the end of Feb in the McGill building. If you want, I can bring a couple cases down especially for you.

For break-in, most everyone in USA can buy everything locally...

HEET gas line anti-freeze is pure methanol and can be bought by the 12oz bottle.

Castor can be bought at the hobby shop, look for SIG Castor Oil.

If you are going to just use it for break-in, medicinal castor oil can be used, however some suggest not using it because it is not grade AA and will cause carbon build up over extended use.


(1) 12oz bottle of HEET to 2.4oz of Castor = 80/20 fuel.

Calculator: 12 x 20% = 2.4

jetpack,

As they say "do the math". Adding 2.4 oz to 12 oz methanol is not 20% castor because now you have 14.4 oz total.

Proper math is 20% of total. Since 80% will be the 12 oz methanol then the total will be 12 divided by 0.80 which is 15 oz total. The other 3 oz are castor. Your mix would be 16.7%.

Easiest way to get 20% is one gallon of methanol plus a quart of castor. Simple. Finding the methanol is the hard part.

20% castor can be mixed in the following ways..
4 teaspoons of methanol and 1 teaspoon of castor..
4 eggcups of methanol and 1 eggcup of castor...
4 pints of methanol and 1 pint of castor...
4 tankers...............................................................................

Badger your right!

That's a big OOP's on my part...hope nobody blew up a new motor!

I should have thought better. I used to even do percentages as part of my job at one time...how it slips away...Thank you for the correction!

Downunder has the right train of thought also - a 4:1 mix. Much simpler for us with simpler minds.

Did I get the ingredients right?

Methanol is usually easy to get depending on where you are.

When I lived in California, I used a speed shop in a major town and bought methanol by the gallon and brought my own jug. I ordered the oils from Sig.

Now living in the Yukon everything freezes up here including your car. I buy Methanol at the industrial supply by the gallon.

I would definatly mix my own. I have also been able to keep mixed fuel good for a very long time by not allowing air to touch the fuel for very long. After mixing I pump propane thru the mix and also use the gas to propel the mix when filling the fuel tank as well. The propane displaces the moist air which can put water in your fuel. I use a 3litre pop bottle for the fuel and propane torch with the head cut off and a mini regulator for the pressure. I have had 3 cups of fuel remain good for over 5 years with this method. Plus side is no noisy pumps when filling your plane
