Designing planer boards is a hobby I am hooked on and wanted to share my ideas and developments.
Anyhow, I'm testing wings and tails on small custom molded foam planer boards. I had the foam bodies molded in China in 4 sizes. I am drilling the hole and cutting the slot and inserting different shape wings and tails in the slot. I cut the shapes out of a milk jug. The foam bodies I'm testing are 3" long.
This is a close up of P3 pulling a lure larger then itself. The wing kept the attack angle stable at speeds from 0.2 to 2.0 mph. The furl off the keel hits the wing harder the faster you go keeping it stable. Forgive me for struggling to explain how it works, I'm still trying to mechanically rationalize my observations and put them into words!
Here are P3 and P5 planing way out to the side with large lures.
