The wings were modeled in SolidWorks Maker 2023. They were scaled to my height and mechanisms were designed to let them fold smoothly. I specified a linear actuator with enough torque to extend the wings and sourced carbon fiber tubes to reduce the overall mass. Feathers were cut out of foam using the laser cutter at my local makerspace and attached with zip ties and yarn.

The bill of materials for the wings are listed in the drawing to the left. The measurements are slightly out of date, but generally reflect what was built.

The clevis rod ends were glued into the inside of the carbon fiber tubes with marine 2 part epoxy. The shoulder bolts were stainless steel; I initially tried to use Nylon bolts but they proved to be not stiff enough and were bending under load.

The linear actuator ultimately used was a L16-100-150-12-S from Actuonix. This is a limit switched based actuator with a maximum load of 44lb. The motor was driven using a L298N motor driver and powered with a 4S RC battery. If you're reading this because you're looking to build this, I'd recommend evaluating the total mass of your wings and seeing if you can use a smaller gear ratio L16 (like the 1:63 variant of this actuator instead of the 1:150 I used) to try to get some more speed out of it. I wouldn't recommend the L12 series for this, and readers should consider L16, P16, or T16 from Actuonix.
