If getting a instructor is not easy for you to do, than a sim is the way to go. I taught my 7yr old on
RF5 and he can fly and somewhat land my slowstik. What i think this can help with is mastering
the old left/right going away, coming at you turning thing, help making it become reflex instead of thinking about
it. Though the sim will never replace the shakey hands,fast heartbeat and tingle in the nads on the first few flights,
it will help master some basic skills in how a rc aircraft react to inputs from the pilot. Nothing can replace a real instructor
but the sim will help get you there to, just dont get caught up in wanting fly a p-51 as you first plane...slow and low wing
loading is your friend.
