I can appreciate your problem, Elvir. That's why I got into gas for the bigger airplanes! Just getting into pattern, and a good friend and some others got me in on a deal to buy glow fuel in bulk, so I mix 15% and 30% and it comes out to about $8.50 per gallon. Even so, gasoline is about $3 per gallon and gasloine engines use about 1/2 the fuel as same displacement glow, as I'm sure you are painfully aware.[]

At present my only gasser is a 27% H9 Extra (with Brillelli 46 cc), but if I stay with pattern -- as I likely will bcause of its discipline -- I may get an airplane that is compatible with the zdZ 40.

60% nitro for boat?? good luck!!![X(]
