The 4* are an easy fly but have to be slowed to almost a standstill to get it to stop flying. This makes it a lousy low wing trainer if your next plane is going to be a warbird. I know its not on your narrowed list but maybe take a look at a Carl Goldberg Tiger 2. The landing is a more positive approach. Its glide path is more solid and predictable and it comes so that you can set it up as either a trike gear or tail dragger. You can start as a trike and then switch to tail dragger once you get used to how it flys. [8D]
