Trim it for the approach and you should easily be able to overcome trim forces to flare.
Once I get the hand of finding the trimmer by feel alone...!! There was at least 1 approach where I gave up and just because I needed my hand on the throttle instead of fumbling around for the trimmer.
60mph didn't feel too fast - we didn't float for too long. The instructor and I are both starting our diets tomorrow.
And the runway has a bit of a slope so you need enough speed to round out to a climbing attitude. Still, the instructor was fairly new to Cubbing so he might have had me approaching a bit faster than needed.
Thanks for the supercub.org link!
