What's better than two rotors, one wing, and two control surfaces? Four rotors, two wings, and 3 control surfaces. So, after modifying the Twin Twirl for foam board the Quadratwirl was the next logical step, and should be a fun combat plane for Flite Fest 2022.

Parts list:
- foam board (of course)
- Power Pack C motor or larger and an appropriate ESC
- 3 9 gram servos
- landing gear wire for rotors
- wheel collars for rotors
- brass or steel tube for rotors (to reduce friction)
- 3d printed parts (PLA should be fine)
- string or dowels for wing struts
- bbq skewers for elevator struts and rotor pylons
- for the double thickness wings, glue together with high strength spray glue and seal the edge with hot glue
- for the rear wing have the paper sides of the hinges facing each other for more strength
- follow the method in Flite Test's Twin Twirl build video for gluing the rotor blades (around 5:32)
