Everyone is different in how much time it takes to learn the basic flight skills. I imagine those of us that are in clubs with instructors would learn faster than those who are self taught.

There is an amazing heli pilot at our field. He started in the 80's or early 90's, but had a tough time mastering the skills. He started flying planes in the mid 90's, and got back into helis in the late 90's. Now he is totally amazing at flying a helicopter - a real pro. He said learning to fly planes helped him a ton with the helis. Maybe this will help you out, too

If you're not going to get an instructor, definitely get a simulator. FMS is free at www.rc-sim.de . It's a bit crude, but it teaches your thumbs the right movements. Clearview is a bit better, and is maybe $40 or so.

If you are going to fly with an instructor you don't need/want any sensors on your plane. I just say this because I've heard so many people say to remove them or turn them off if you can, though I have no personal experience with them. With an instructor, they can bail you out of a situation, tell you what happened, and give you back control. The sensors might be working against you without you knowing, therefore not teaching you as well.

Good luck!
