Just to set the record straight, someone suggested a Great Planes Corsair. Great Planes actually makes 2 entirely different Corsairs, one an ARF and the other a kit. I'm sure the person who made the suggestion was refering to the kit, which is a relatively tame warbird. The ARF version tho, is NOT for the beginner (or for the experienced, in my opinion). It has a much higher wing loading, even higher than the larger Top Flight 60 size Corsairs.
But, my first pick would be the Sig 4*40, which was I learned to fly with.
