RE: On my first flight I...
You want to 'prove' that people can train themselves? This sounds pretty much self-serving. You want to try to justify your activities without an instructor to us? Sort of preaching to the choir.
If you read other posts, and I can gurantee you that there are literally hundreds of them, about people trying to train themselves to fly RC, you will find the answer to your question.
If you insist on trying to learn to fly RC yourself, without an instructor, well, knock yourself out. Have a ball. Make sure you have a high limit on your plastic, though. Then, once you are convinced that you probably made a mistake, get yourself a good trainer, or rebuild the one you wrecked three or four times, and get in touch with an instructor and go for it.
I don't quite understand the reluctance to get an instructor. I believe the cost is minimal (how about free..) so it can't be the expense. Could it be bravado? Ego? Hmmm?
It's already been proven that a very small percentage of people that try to teach themselves are successful. Why try to change the numbers that prove the point already?
