Going it alone when learning to fly RC is indeed possible. Myself and plenty of others have done it. However, I bought a simulator, and had 6 years of RC helicopter experience by the time I got into planes. Planes like the Hobbyzone Champ, Super Cub, Firebird Stratos and the Ares Gamma 370, along with the simulator and plenty of practice, all made it possible for me to fly more advanced planes in about 6 months. Flying an RC aircraft is a pretty difficult thing to do, more so if you don't take baby steps and try to fly a plane like the bomber you described. That is no beginner plane. I agree that probably the easiest way to learn is with a club instructor, but if you do insist on goin it alone, then try the planes I listed and you should be able to learn on your own. It will be painful, but it can be done.
