Actually, the Super Three had a shorter wing span, 90 feet v. 96. Ours had 1820-80 engines, 1475 hp. The rudder was a joke. Yes, it was taller but had no throw. The USMC had a hard 10 knot crosswind limitation, all that extra surface caught the wind and you had nothing to straighten the plane out with.
I've heard of putting R2000s on a Three but never flown one.
