Wingscrew Quick Release for Banggood Skysurfer

Quick release mechanism for the Banggood/Aliexpress Skysurfer (Easystar Clone) 

Extra components: 
-the 2 wingscrews from the Skysurfer (or 3.5x70mm Bolt)
-2 compression springs with fully compressed length ≤ 5mm, outer diameter ≤ 6mm, fits over screw, extended lentgh ideally ~ 20 or more to pop screw out. Found mine in this set: https://www.hornbach.de/p/zug-und-druckfeder-set-200-tlg/5148741/

Assembly: 
Saw the screwhead side off the original screws, so you are left with a 70mm bolt
Glue the printed screwheads on (any side should work, maybe use the threaded side to cut into the hole for tighter tolerances)
Glue the spring base to the screwhead base (Only neccessary to retrieve the spring and not loose it)
Glue the screwholders to the wooden board on the plane, where the screwhead would normally sit

Usage:
Put the wings in
Insert the screw fully with a flathead screwdriver
Turn right 90°
Let go
