Multicopter feets for Alien 560 Folding Quad

thingiverse

Alien 560 Folding Quad human feets utilize four propellers attached to a central hub by rods that form a square structure. The arms, also called rotors or motors, are secured by mounting them perpendicular to each other on opposite sides of the centerboard frame allowing all the propellers to move freely without restriction when tilting in flight due to differential rotation creating lateral forces. This design configuration gives better maneuverability, agility and high thrust capabilities for transporting cargo.
