Your asking about equipment that that you really are not anywhere close to needing. Get one of those package trainer deals like an Alpha and learn how to fly. As your knowledge of the hobby increases these questions will answer themselves. You have a very steep learning curve ahead of you which if you are lucky, you may figure out how to fly a trainer by the end of the summer if you start now. Go join your local club, find somebody to train you and buy what they recommend as a first plane combo. If it survives, you can sell it to somebody else and move up. Helicopter's are a long way off and I'd worry about them after you have figured out how to fly the left stick as well as the right. This RC thing takes years of hard work to get any good at, and who knows you may quit after you splatter your first plane.
