If you insist on going it alone just be prepared for some frustrating moments. I would suggesst finding one of the cheapest slowest flying planes to start. there is no doubt you will trash it eventually. Find a feild with plenty of un-obstructed view and play away!
Another suggestion is try to find a hobby shop that has a simulator on display. take advantage of experimentng on that as much as possible. they will let you continue to use so long as you are loyal to their store.
This is a wonderful, exciting and addicting hobby, i wish you the best!!
