RE: Extreme Flight 87" Yak 54 - Build & Fly
I would venture to guess you can get 30 minutes of normal flying out of the 20oz tank and the DA50. It sounds rediculous but i had the same setup in my Double vision and i could fly it until i was tired of it and then land and there would still be half a tank of fuel, then hand the transmitter to someone else and let them fly it until they were bored. You could easily get away with a 16oz tank if you wanted to. I had the stock muffler so don't know if the 1060 pipe will change the fuel consumption at all but i can't imagine it would be much!
