Seagull Decathalon completed!! First flights done, experienced guy flew first flight snap rolled the bejesus out of this bird, my flights were less spectacular, but great flying plane, looking forward to learning on it. Have Irvine .61 2stroke. Only mods I have to make is to open the cowl a bit in the back, the bird just got too hot, and rebuild the fuel tank holder to fit some foam and lift it up in the air frame a bit to facilitate fuel flow to engine. Engine was either too hot or I was foaming the fuel. Really like this plane!
