Might have found me a source for a single gallon of FAI fuel for my poor old Webra 40. Best part is, it'll be an imperial gallon of roughly five liters instead of four quarts for sixteen bucks.
My local club has made arrangements with Magnum Fuels for discount rates on imperial gallons. I'm getting the usual 15% nitro/18% oil stuff with a separate order for 0% nitro/20% oil FAI if they'll send some as part of the total order.
If Magnum will ship a single gallon of the FAI, I can have fun with a vintage model with a vintage engine and it'll free up my modern Magnum XL .46 for use in a Great Planes Ultimate Biplane I'm working on.
Fingers are crossed; this may be the best sixteen bucks I've spent in a long time.
