Puttin this thing together and this is my first ARF. Does the fuel tank only need 2 lines (pressure and feed) or do i have to install my own vent? Fired up the os 61fx for the first time and when i went to fill it thru the exhaust pressure hose, it shot right thru and out the carb line (both were disconnected btw) on an empty tank. what am i doing wrong? i know the air in the tank has to bleed its way out but the only way i can think of fueling this every time is taking off the spinner, prop and cowl, and pointing the nose straight up. seems like a lotta work to refuel(as compared to my nexstar) do all enclosed cowl planes fuel this way? this is the stock tank that came with it (with 2 lines) and my nexstar has 3 lines. They should make these things a little clearer to noobs like me! PLEASE HELP! Thanks guys-
