I got into the hobby in 1970 and have been hooked ever since. I learned very quickly and a year later began giving flight training. I started teaching using a buddy box, but my students were banging the sticks around, so I reached over and put my thumb and forefinger underneath the student's thumb on top of the aileron/elevator stick. That ended the stick banging and I could easily monitor what his thumb was doing, and I could easily correct him, not allowing him to make any mistakes. My only purpose is to get more people into the hobby/sport.
