RE: Should I drop a GP Cub 40 for a different plane?
Build the CUB, it will train you an a lot of the needed skills for a warbird. It will teach how handle a taildragger, and it will also help you learn to coodinate you aileron and rudder in the turns. It will be a good tool for learning to rudder at all times in a flight. When you build a "real" warbird, you will need all those skills and more.
