No fool like an old fool that thinks about a Flying fool. I’ve never used the several different heat shrink cover material. It’s become really popular​​​​​ and many suppliers have several different brands. In my old ways I’ve used Silk to cover all my wings. Even in RC. Which I put up about two years ago. Took my RC stuff to a swap meet and never sold anything. I had nothing in electric, and that’s what was selling. So it goes in 24, and the times are a changing! Often wonder if guys are having any buyers on the old kits like the Flying fool, S-1 Ringmaster, or the Super Ringmaster? AJ.
