Staudacher, I'm from Charles City, IA so it was only 1 1/2 hr drive up there. My dad and I had the Big Hots, Somethin' Extra, and a JR Venture CP. We were sitting right next to the guy with the Funtana. I guess I thought both tanks work gas because he was flying at least 15 min. at a time. Well I guess he was never wide open except for power outs when hovering.
