ORIGINAL: badangle

bookerglad to hear of your success....if you remember I was thinking of getting same plane but went with ziroli stearman...but now I have to build it.can you tell me what the weight is and what kind of performance the 7-77 delivered?
badangle - I can't give you an exact weight as the wings are off for transporting to the field. I'm guessing around 24 lbs. but I'll weigh it when I go to fly it again.
The 7-77 had way more power than was needed to fly it scale. It ran just excellent - never missed a beat. When I was taxing out I let the idle get to low and the engine quit. It took only one flip of the prop to get it going again. A truly impressive engine.
