Fwiw, I totally agree with what Chuck just said. I'm not against guys learning on their own, and I that plenty have in the past.

But I also do a lot of flight instruction, and from what I've seen the vast majority of students I've worked with would never have managed to learn on their own. Not all, I have had a few "natural" students who only needed a couple of lessens and were off in no time. But they are the rare minority.

Also, the aircraft selected for a trainer, second, and even third airplane can make a huge difference in learning by yourself, while with an instructor, the aircraft is a much less important element, and the choice of a second and third airplane matters even less as far as exact model goes.

There's not a glow trainer on the market that I'd recommend to anyone flying by themselves, fwiw. If nothing else, every one of them can have problems due to being mass-produced products. With out help, you'll never know if it's your or the plane.
