UAV Coaxial Copter Uses Unique Drive Mechanism

Coaxial vs Conventional Helicopter & Tilt-prop VTOL Aircraft Designs

Knowledge | Curiosity | Discovery on Instagram: "This video captures a unique and powerful sight: a small, red helicopter operating on a grassy field, distinctly featuring a coaxial rotor system. Unlike traditional helicopters that use a single main rotor and a tail rotor to counter torque, this design uses two main rotors spinning in opposite directions on the same mast, eliminating the need for a tail rotor.
