Animatronic cosplay wings- moving four wings with one servo!

OK folks, this took forever to figure out how to build. This was an incredibly difficult project to figure out. The goal was to make four moving wings but also have it be light weight, low power, compact mechanism, etc. The original mechanism had eight servos, then six, then five, and now just one.

So here's a single servo mechanism moving four wings with a raising/folding motion and it's doing it on 4.8V

IF anyone is interested this mechanism is now for sale!
