I don't mean to be rude, but you've got over 800 posts here. You know how this place works by now, do a search.

A trainer is an airplane you use to learn how to fly with...They are slower, easier to fly, and usually very simple. It makes learning go much faster...

See if you can find the local flying field in your area and take a trip out there. Then you can see them for yourself and see how it all works...Seems like once the car guys try airplanes, they NEVER go back!
