Another point on this interesting discussion;

We are not talking about identical airplanes here, so we really need to take that into account.. My early Avid Flyer weighed 400 lbs empty and would safely climb out at 45 mph at a 47 degree angle with no issues at all since the stall speed was 22 mph. But it (like Kitfox 1 -3 Models) had a completely different airfoil than later Kitfoxes. That airfoil will fly (and stall) much slower, and land much shorter than the newer airfoil design. So in this discussion it is almost like talking about two completely different aircraft.

By comparison, I climb out in my Model 4 Kitfox amphib at 65 to 70 mph. I can climb at 45 mph, but it doesn't feel right and makes me a bit uneasy since my stall in that configuration is approaching the 40 mph range. So I avoid using techniques like that.

And even though we need to consider the huge variety in our airplanes, this has been a very good discussion that could prove beneficial to all of us.
