Abstract
A propulsion unit includes a motor rotor, a clip-in base mount, a clip-in rotor cap, propeller mounts, and propeller blades. The motor rotor spins about a central rotational axis. The clip-in base mount is disposed on the motor rotor. The clip-in rotor cap is shaped to mate with and detachably clip into the clip-in base mount. The propeller mounts are attached to the clip-in rotor cap. The propeller blades each have a proximal base and a distal tip. The proximal base of each propeller blade mounts to a corresponding one of the propeller mounts.
