My point exactly. Electric Pattern is very affordable however. Also, you can still do glow for under $10 / gallon if you buy 55 gallon drums. At 16 to 20 oz a flight, it works out to about a buck a flight. Fuel costs aren't really the big cost issue though. If you can afford the support system for hauling multiple 40% airplanes, more power to you. I never got past using a minivan for my 40% stuff, so I always had that chance that I would be at a contest with nothing to fly if I had an equiment failure. It never happened, but it always bugged me that I could not bring a backup.
