I run realflight sim and still have not masterred hoverring. Keep in mind, it has been a year!!!!! I fly planes and have NO problems there. Heli's are a world of their own. Even real heli pilots crash them many of times.
Best bet would be to buy a SMALL electric and get that one masterred first.
My .60 class raptor cost about 1,200 and I still havent flown it!!!! Not until I master the sim. And even then, I am going to a professional flight instructor around here and paying the 200$ to learn how to fly the real deal. Good thing is, they are his helis that you learn on.
