I wouldn't quite suggest starting off with nitro fuel planes. They are fairly expensive, and you will need fuel and equipment, which seems a little too much just starting out. Also, it is indeed expensive to join AMA and the club, so I would stay with something around the electrics suggested.

Now I know it may seem that you that sims are good experience, but you do have to face the facts that the real world can be a big difference. Of course it does help and that will go towards your credit. Also, do realize that although it says ARF, it means you have to install: motor, servos, reciever, battery, most likely control surfaces, and if the plane it not already fully assembled, that as well. This involves a lot of work, and it can cost you if it is not done properly[:@]. Now, I'm sure you want to do all sorts of aerobatics, but you do have to make sure you can fly first you understand. I know that you may not like it, but I'm going to have to suggest a slow stick. They are just solid planes, easy to build and fly, however I have seen some great things out of them, so don't count them out of aerobatics(especially with brushless). There are just some times when you want to have a relaxed flight too[8D], so putting all of your money into an aggresive plane might not be the best idea. After all, you are supposed to have fun doing this. I don't want to sound all preachy, but thats what I think.
