Yes, boy did that thread cause some problems someplace else. An interesting plane, that flew well, but it's engines made outdated. It would have been interesting to see fly with Jet engines but in reality, everything about it would have been needed to be redesigned, as the planes forte was how slow it could fly, not something looked for in a fighter.
The Vought XF5U seemed like a better incarnation of this beast. It was a pig though and vibrated so badly, it was never flown. Same Gearbox problems. Modern materials and computer related aerodynamic studied have produced aircraft that are lifting bodies. It was kind of ahead of it's time. It also had propellers, which were being phased out of most new aircraft for the role intended.
It's good that these guys restored this plane, a piece of history. If it could be made to carry six people or so, and with a different prop arrangement, an STOL aircraft like that we be great to fly and better for General Aviation, but it will never happen. The Piper Warrior I flew carried 4 people, went faster, and with only one engine, and easier construction, again you can see why craft like these were destined to failure.
