The company [Chance Vought] pilots had been flying it up to this point, and a few senior Navy pilots had made brief hops in it. The pilot who flew it just before I took it on was D.C. ‘Whisk’ Caldwell. The F7U-1 had one of the first hydraulic flight-control systems. To build feel into it, they had built a heart-shaped cam with a roller on it on the bottom of the control stick. Caldwell took off in the plane one day, and the throw on the stick somehow sent the roller over the edge of one of the lobes on the heart-shaped cam. Caldwell was immediately faced with a partial
control reversal. When he pulled back on the stick, the airplane went down, and when he pushed forward on it, the airplane climbed. Lateral control was normal. So, he flew around for a few minutes while the base crash crew scrambled and debated whether he should eject or not. He thought, ‘I think I’ll take a little time and see if I can fly this. I think I can land the airplane.’ Sure enough, he landed successfully and rolled in. He got out of the airplane, walked straight into the hangar, sat down at his desk without even taking off his helmet and wrote his resignation from the Navy and quit right there! That’s when I inherited the project.
â€¦[O]n almost every flight, we lost the hydraulic boost and ended up flying on the mechanical backup system. It took 11 seconds to engage the mechanical system, and you can’t imagine how long that seemed. We had constant hydraulic problems. I probably had 370 hours in the F7U-1 and I can’t ever remember once writing ‘OK’ for the hydraulics on the yellow post-flight evaluation sheet. Something was always wrong. The Vought engineers practically rebuilt the Dash-One. They were wizards at coming up with fixes, but the Cutlass sure taxed them.
Not all was doom and gloom. In the hands of a careful, skilled pilot, like Whitey or the late Wally Schirra, the Cutlass could perform masterfully. Schirra has said that no other aircraft could turn or match his roll-rate in an F7U-3 at altitude. With a pressurized cockpit, that altitude could be as high as 50,000 ft and as a weapons delivery platform, it was relatively stable in delivery mode. Unfortunately its range was horrendous – with a combat radius of around 150 nm it just wasn’t going to go very far with conventional ordnance, much less with the big and heavy first generation tactical nukes. In Vought tradition, it was a good gun platform, with the singular exception of the location of the muzzles under the cockpit created a good bit of flash which took the Cutlass out of the night fight. Around the ship, the Jekyll-Hyde nature continued. With fistfuls of drag, the Cutlass was relatively stable around the pattern with high levels of power utilized to control altitude. Unfortunately, the early models had atrocious over-the-nose visibility, which raised adrenaline levels with the â€œcut signal from the LSOs:
“When we went to the [USS] Midway (CV-41), an old straight-deck carrier, to do the first carrier landings, we discovered that the problem was worse than we had thought. On the first landing, when I got in close, I didn’t realize that I was skidding the airplane to keep the LSO in sight. He was almost abeam of me when he gave me the cut signal. When I took the cut and looked forward over the nose, I couldn’t see any part of that carrier-nothing, not even the stacks- just water. I knew I had been cut late and I did what I had schooled myself never to do: I dipped the nose because I thought, I’m really going up the deck! I’ll miss the barricade and go into the pack [of parked airplanes] up front!’ Well, instead, I snagged the number-one wire. The minute I dipped that nose, the airplane fell straight down. I barely made the flight deck! The tail hit eight feet from the ramp and scared the LSO to deathâ€¦We continued on with the trials, making landings 15 feet off centerline, left and right. On the last landing, the LSO was so nervous that when he gave me the cut, my landing gear was 33 feet above the flight deck! We had pictures to prove it. Not being able to see the deck, I just let it drop from there. I waited and waited to touch down, and just as I started to worry, blam, the airplane hit the deck, and it sounded as though
somebody had taken a big flat board and clobbered the wings with it. The fuselage broke behind the cockpit and you could see daylight at the midpoint, but it didn’t collapse on the deck and break off completely. That ended the project, but we still hadn’t reached the yield on the nosewheel!
Along with the re-design to accommodate the engines, the cockpit was redesigned as well to afford better visibility over the nose. Still, there remained enough problems with the aircraft that the navy eventually brought the program to a halt and by 30 Nov 1957, the last Cutlass departed from squadron service. Over the course of its brief life, the Cutlass claimed 4 test pilot’s and 21 fleet aviator’s lives and while deployed with several squadrons, never saw any combat. Yet what Vought learned in the process helped form the quintessential single-seat gunfighter, the F8U Crusader.
