Flieger - the Funtana 90 is a slow plane in the sense that you do not fly it that fast. I fly at about 40% max on level flight. When I go vertical its 100% throttle and prop hangs are at about 55% throttle. Tank is the standard one ... I think about 14 oz. Fuel is Cool Power 30% heli. I did run a TT120 2C also and I could get about 8 mins flight at about 125 ml, not sure how much in oz. That is on my 1/4 scale LASER 200.
