You didnot have to be in the milatary to lern to do a roll as Hoss has dicribed it. When I got my privet back in the early 50's we learned ti that way in a PT-22 it was a bugger to do at frist, but once you got it it was easy. Then when I was into rc learning to use the thumbs was a bit tugh but you get over it, thke off's and flying was always the easer but landings you realy have to practice
