Then the 4* or the Tiger will be good... or a Super-Stick (almost any stick) relatively small step up from the traner so you don't have a huge problem dealing with the differences, and much better aerobatic capabilities.

The Tigers are heavier than the Four Stars... and handle wind a little better. The sticks can usually outmaneuver either the Four Star or the Tiger. (Ultra-Stick is a much larger step up iin maneuverability than the Super Stick...)

To move up toward scale warbirds... you want taildragger. (any of the above can be converted if not already taildragger) and you will want ot increase weight for some take-off and landing practice (but no aerobatics while ballasted) before going to the warbird. (after you are VERY comfortable with the aircraft you are making heavier.... and add weight to it SLOWLY)
