Throwing would make a short flight, but would ground take-off actually be able to get the plane (though only momentarily) into the air?The way I see it, takeoff is just like a person "throwing" an airplane, though now the airplane is doing that throwing by itself. If the airfoil is good, it should get the plane up into the air even just for a moment, running only on the thrust made by the takeoff, right? Or is that nonsense :P

And on the engine, is there some sort of relationship between model weight, for instance, and an appropriate engine + propeller?
