He tells me he learned the art of free flight aviation with the Strat-O-Bats in Seattle, WA. After being away from that hobby for more than twenty years he downloaded the free Squirrel instruction sheet and made this model.
This model so happens to have the world record flight of 1:14 (one minute and fourteen seconds).
Well that’s what I believe. Donald has the record (from the following video) and I’m assuming it’s the same model in the video.
