My brother has the old Kyosho 40 size AT-6. The full scale had the reputation of tip-stalling at low speed and the Kyosho model absolutely loves to slam a wingtip into the ground if it gets too slow on approach or if it doesn’t have a lot of speed when taking off.
Fly your new four star for a while. It really will prepare you for the next step which could be a warbird.
I have a Great Planes 40 size Corsair. It is a kit so it takes a while to get it going. I started the kit and my brother finished it. It is far from being a scale model but it does look like a Corsair from a distance. We were afraid of it before the first flight. It does not have bad stall characteristics but it does need to land pretty fast. The Great Planes 40 size P-51 is another kit that is reported to be a sport plane that looks like a warbird. Either of these planes could be a good first warbird before getting into bigger models with a lot of scale details.
You could even look at the rules for RC aerobatics and practice the maneuvers with the four star.

Even if you have no plans to compete you will be putting the plane in lots of situations that you will have to recover from.
