RE: Who says flying is difficult?
As for the thread as a whole, sure there are some that can learn on G-2 and then learn on their own, but putting up a general statement that flying is easy and people should try it on their own is just plain wreckless. People can get hurt very easy with this hobby.
If there is an instructor close, by all means use his expertise to learn the hobby and don't chance hurting someone or wrecking your plane on the first flight. Sure some people can do it, but if you can get help, why risk it?
