I remember when my instructor took up my second plane for the first time quite a few years ago. I had it setup perfectly. Ailerons, elevators, rudder, all in perfect alignment. That thing should have flown perfectly straight right off the deck. Should have. But it didn't. As soon as the plane broke ground it was all over the place. The instructor, a very good experienced pilot, was do'in the dance as it went this way, then that way, up, down. He was all over the place. And that was all in about the first 2 seconds. I did not have the kind of reflexes yet to save a situation like that. It would have been a smoking hole at the end of the runway. Once he got it level and straight, he trimmed it just a little here and there to fly straight and easy.

Get an instructor.
