The original prototype all-metal UltraCruiser ultralight designed, built, and flown by Morry Hummel was flown to AirVenture from central New York state by its new owner Kirk Mills. It was his first long cross-country flight. The engine is a two-cylinder 1/2 Volkswagen that gives the FAR 103 legal ultralight a range of nearly 150 miles. He had planned to have some flying companions but ended up going solo.
The challenges were significant for a relatively new pilot. The engine crankcase cracked just two weeks before the flight and had to be shipped off for repair. During the trip he had to make a couple of precautionary landings in open fields because of bad weather. Most landings were at airports, and the fuel most often used was 100LL avgas. He carried an aviation handheld radio and a GPS. Kirk said the people he met along the way were incredibly friendly and helpful.
The flight was plagued by worrisome erratic fluctuations in the engine oil pressure that were traced to a sticking check valve in the oil system. He had a ground support vehicle for the flight to Oshkosh but will be returning home to New York unsupported. His friends thought he was crazy for trying it, but he believed he could do it because a long cross-country flight is just a lot of short flights strung together.
