Actually Bob built three F-86 Sabre Jets. The one Clint is reprising was the first one, and I watched Bob fly it at every local contest in 1969, and at the Nats. He won every meet he entered that year with the F-86, and he called his shot before the contest year began. He declared even before he flew the Sabre for the first time that he was going to win the Nats that year. Amazing!
Bob followed up with a larger version of the Sabre that was built around a Shark 45 wing. It had a Fox 59 for power and it did not live up to Bob's expectations, but he still finished fourth at the Nats with that ship.
Bob's third Sabre was built around 1972, and it was again a 35-size ship. When Bob took that plane to Flushing Meadow park to test fly it, Gene Schaffer was also there testing his third Stunt Machine. Gene's was having a lot of trouble getting the Stunt Machine to trim properly and - as he was prone to do - just started a wingover on one flight and decided to just not pull out. The Stunt Machine hit the asphalt dead vertical at speed and the engine was catapulted into the air. It landed right on Bob's new Sabre! Fortunately there was minimal damage, but Bob was furious. He had to make a new flap for that plane, and I don't recall seeing it fly at any contests after that. It may have, as my memory is a bit fuzzy after 51 years... I do remember that the third Sabre was just flawless in build quality and finish; just like all of Bob's airplanes!
