Jim it sounds like were a lot alike on our maiden's, including the shaking. And I as well don't do it with someone else's plane. The first and only low and slow it almost stalled but maneged to throttle back up and go around. I as you like to do a few loop and roll's and straight away at an upward climb just to check trim's and thrust. It went much better than I expected. The plane has so much clear tape on it holding the covering I  was a little leary. Whom ever had it before me must have liked poking hole's. Was also a little worried the little 20cc would not be quite enough  but turned out to be plenty. Anyway's Thank's.
