I myself have been self taught. I would highly recommend these points-

1. Again, get a simulator and cheap controller. I bought my first sim at clearviewrc.com for 39.99. I picked up a cheap USB controller for 23.99. I also have FSOne, which is much more realistic, but the thing you are going for on a sim is orientation and hand eye coordination.
2. I would highly recommend the Hobbyzone Supercub, Supercub LP or Mini Supercub. I moved from sim to Supercub with little problems. (in addition, a new wing is 10 bucks)
3. Find lots of room...big field with a very smooth surface or road to takeoff or land on. You can hand launch most electrics, but I find it more entertaining to takeoff and land realistically.
4. When ready for a nitro or gasser, dont jump the gun. Keep flying the electric. You need alot of stick time before you move up to the nitro or gas planes. To me, they are easier to fly than some of the aggrevating electrics, but they cost alot more to rebuild/repair.
5. Patience, Patience and forums. A good beginning is to keep on these forums. You will find a tremendous amount of invaluable information on these forums. Most questions are answered by experienced and/or professional folks who have been where you are.

I have had no time with an instructor, and have been flying nitro for about a year, year and a half. I have had my mishaps, but I dont think any more than anyone else does. Lost one nitro trainer due to not thinking ahead. I was paying no attention to the large pine tree ahead of the plane...I have been flying my other trainer for a while now and have had no mishaps. Many people have learned this way, and you can to....it just requires alot of patience...

Good luck and keep us posted!!!
