RE: next plane
Sorry Toothman, but I have to agree with Squeekalong as well. Let me try to give you a little perspective on what he is trying to tell you.
You have an arf that you assemble the pieces. Think of it as a bicycle, not too hard to handle
The suggested 4Stars, Eagle and Tiger II would be like driving a Ford Focus or Pontiac G6, not to difficult and not to powerful for a beginner
Now lets look at the warbirds you listed, think NASCAR to Indy cars. Only someone with lots of experience can handle them and one wrong move can total them.
What you might do is build a couple of 4 Stars, Eagle's or TigerII's. Set one up with tricycle gear per the instructions and later build one with a tail wheel to learn how to handle a tail dragger since a tail dragger handles a lot different on the ground
