Sorry but I need to add one more comment. Anyone who claims to know "Everything" about anything is quite simply lying. I would be a little bit careful about two things here, one about taking advice from professionals in a hobby shop who have a vested interest in what to sell you and two about anyone who knows everything there is to know - be very careful of such people. My point was that you should visit the local flying field and find somebody who will take the time out to actually teach you. Then follow that person's advice about everything.
