Guys,
Bill Hinnant was my father he designed the F5. I went with my dad to many contest growing up and the plane flew perfectly. I think the fuse might have been originally sheeted but he later created a mold and made glass versions. They were all very true and very fast.
Dad was a mechanical/aeronautical engineer who helped design the B-52’s wings and many other projects.
Thanks again for posting his images.
