I learned to fly without a sim--Bought one for my son as a present to suppliment some of his shoot um up computer games--He used it with his electric Zaggi and learned to fly in a short time--My landings got sorry-not crash sorry -just eratic-overshots-prop busting-etc--Got on his sim for 30 minutes and next day landings improved--Now use sim for airobatics-invertered-rolls-etc---Great learning tool--If your flying has a problem you can't seem to click--Try a sim to straighten it out--Oodles
