If you're not too far off the beaten track in Australia you should be able to buy Ether. Di Ethyl Ether, Solvent Grade is the right stuff. This is available legally through the control line and free flight communities.

A basic side port engine should run at least on the old three to one mix. Equal parts of Ether, Kero and Castor oil. Medicinal grade is ok.
A good general mix for all but the most basic engines is 20-25% Castor oil, 30% Ether and the rest hardware store kerosene. To this most of us add 10-20 ml of Amsoil Cetane booster. This is available quite cheaply as well.

Castor oil is readily available although some use mineral oil. I have no experience with it but others seem to like it.

There are no secret recipies.

Hope that helps. Ray
