60mph over the threshold. Stick full back? The trim spring was strong, so I think I goofed on the stick back bit...
Almost certainly too fast, I'd say, but it's obviously dependent on weight and the accuracy of your ASI. More like 50mph over the hedge. The experts will do it slower.
Trim it for the approach and you should easily be able to overcome trim forces to flare. Eat your spinach!
Like I say, the fellows at Supercub.org are the ones to talk to.
