Don't know if anyone will ever look at this, considering how old these posts are, but thought I'd clear a few things for anyone who might.

As far as I know the original plane is in Caldwell. It was damaged in a 1988 crash and was later donated to eventually be put on permanent display, but was never repaired. This was primarily because Gilbert was never able to oversee the reconstruction and he was the only person with intimate knowledge of the plane.

The crash was the result of a faulty rubber belt which powered the single prop. The belt was made from a batch of rubber that never should have passed quality control and it basically disintegrated after 2 hours of use, causing a sudden and complete loss of power. Because he was flying low to the ground and near stall speed when it happened, there was no time to react and the plane was blown into the side a hill near the town of Star, ID. The resulting crash broke Gilbert's lower spine and caused permanent paralysis from the waist down as well as additional ongoing health problems.

The previous landing in the Snake River, if I remember correctly, was due to a problem with a new muffler that had just been fitted, which he was testing for use with the plane. It was a controlled crash landing immediately after take off that resulted in very little physical damage to the plane, no injuries, and was completely unrelated to the later crash.

After the later crash which resulted in Gilbert's paralysis, the whole project was indefinitely put on hold. Due to the injuries sustained he was not able to continue to pursue it as a primarily one-man project and there was no one else to step in and take over. At the time he had a 2 man version of the plane about 50% finished. The single-spot wing was only built as a proof of concept design, and the two man model was the version that was supposed to go into production. His physical limitations as well as a drawn-out lawsuit with Gates Rubber, who had produced the faulty belt, ultimately resulted in the demise of the project.

There never was fire that destroyed anything. Eventually it became too costly to maintain the lease on the two buildings in Nampa (there was a shop/hangar in addition to the quonset hut that he originally worked out of), and the airport had plans for development that involved using the ground. The second, partially completed plane, was ultimately cut into pieces and hauled to the landfill after sitting untouched in his building at the Nampa Airport for several years.

Gilbert died in 2007. He did not have cancer, but passed away from complications resulting from health problems stemming from the 1988 crash.
