First of all this thread is now more like watching a ping pong game, each 'side' getting points.
Let's face it one rule does not fit all. At least care is required whatever one attempts. For a lighter example of flying off too early look at how the Rans S4 behaves.
(I'm told the Aeronca Champ has similar characteristics)
It will fly off too soon if not held down & become almost unsteerable in the air, especially in any cross wind component. Best i.e safe way was always to hold it on the deck till a reasonable healthy speed was judged, then the usual ground effect to consider before climbing out. I realise it's not a mighty 182, but neither were the twins someone mentioned in for much the same reason - just to show you guys not to be so didactic.
