A software engineer who builds drones and uses 3D printing has constructed a single-motor drone inside a bedroom and recorded its flight. Joshua Bird posted a video on YouTube describing the build and explaining how the design maintains stability without a second motor or propeller. The drone uses a hinged propeller and a custom flight controller that adjusts the motor’s rotation speed in under 0.2 milliseconds to counteract torque and control movement. Instead of relying on a swash plate or additional rotor, the system balances reaction forces by accelerating and decelerating the motor rapidly. This approach reduces mechanical complexity and weight compared to conventional multi-rotor designs. The project demonstrates an alternative method for achieving flight control in small unmanned aerial vehicles using precise electronic response rather than mechanical steering.
