G-2 sim. Then put it into practice with the real plane. Took about 20 hours on the sim than about 20 hours on the real plane and more practice. Now I am down tail touching with the best of them. First I started with a Hovering cobra. Did not keep track of time in a low hover engine died plane crashed. Then I went to a Sudokoi. With a little practice I had it down with that plane as well. Then to a Funtana. Engine died in a low hover. I do not know why it died but the plane now is being repaired with a new
ZDZ 40 engine. By far the easiest plane I learned on was the Hovering cobra.
