I trained 3 newbies last month who had bought the higher priced quadcopters. Once I trained them to fly on my LT-40 (no stabilization gizmos), they said their quadcopters were much too boring in comparison. One said he will continue using his, but only for aerial photography purposes. One other newbie I trained did indeed have a trainer with the stabilization feature. He almost gave up the hobby when he crashed into things and after several repairs, he got disorientated and it flew away, as of yet, never to be found. BTW, in my experience training folks who tried to teach themselves, loved to bang the sticks around since they didn't have anyone to explain how to properly move the control levers.
