The Cub I saw used belonged to Gene Zerkel at AK Aircraft Sales. I hung around there a fair bit and was curious why there were hundreds of pieces of yarn taped to the Cub and why they were swapping tires. I spoke with Mr. Nixon a few times about the flights. I don’t recall VGs being part of the tests. I recall they chose it because it conformed to the type certificate with no mods. It was all about tires, and his conclusion was that while big tires affected CG, they did not cause moose stalls. It seemed to me that the tundra tire worksheet came out after that, but I don’t know if it was the result of those test flights.
I’ll have to check, but as I recall, he flew two or three Cubs, one of which had VG kit. yes, problem was finding an unmolested Cub in Alaska. And, yes, the purpose was to document that tires weren’t causing Cubs to fall out of the sky.
