Building the (scratch) Uff Da (part 4)

The previously Unnamed Flexwing Flyer has now been christened the Uff Da. I got three fins shaped to what I’m defining as acceptable and glued them down on a 14″ piece of T-5. The Estes fin fixture’s designed for flat 3/32″ and 1/8″ fins, not shaped 1/16″ fins, so I did it the old fashioned…
