Really I'd skip the sim and just go to flying as long as you take it one step at a time (bouncing around on the ground) at first then move to flying. I'd suggest you wait and save up for a 36 though. it'll let you train in normal (fp (sort of)) then you can gradate you into 3D mode. trust me you'll be glad you did, just as long as you get a brushless system for it.
