The North American B-25. After the T-6, the B-25 seemed huge—but much easier to fly. You didn’t do aerobatics in it of course, and the tri-cycle undercarriage made landings far easier than in the T-6. It was a good aircraft for formation flying and for flying in weather conditions. One hazard in later models was a carburetor super-sensitive to carburetor icing. I can recall telling one copilot not to worry about doing anything but keeping his eye on the carburetor temperature gauge during climb-out and on approach to landings.
