A propulsion mechanism for an unmanned aerial vehicle (UAV) is disclosed. The propulsion mechanism includes one or more blades configured for rotation by a motor and a hub configured for coupling to the motor. The hub includes a spring plate assembly. The spring plate assembly includes a hub plate that includes a mating portion, a pressure plate that includes a keyhole that receives the mating portion of the hub plate to couple the hub plate to the pressure plate, and a biasing member configured to be disposed along a shaft of the motor between the motor and the pressure plate. The one or more blades are coupled to the hub between the hub plate and the pressure plate. Additionally, the biasing member is configured to increase friction between the one or more blades and hub plate.
