Going back to your original question that you want something, preferably a warbird, but didn't have a lot of experience with the rudder. Unfortunately most every warbird is going to require use of the rudder in order to fly them. Just the nature of the beast with warbirds unfortunately. If you want something that's easy to fly like a 4-star but that you can practice your skills with the rudder you might want to think about a BTE Venture 60 from Bruce Tharpe Engineering. Bruce designed the original 4-Star 40 and 120, but they made the 4-Star 60 after he left Sig. He designed the Venture 60 as what he would have done and it is truly fantastic plane. It's a good building plane that flies great. You might want to take a look.
