Abstract
Various embodiments of an unmanned aerial vehicle are disclosed. In some embodiments, the UAV includes a motor assembly rotatable about a rotation axis and a propeller hub assembly removably engageable with the motor assembly. The propeller hub assembly includes a retainer configured and dimensioned for engagement with the motor assembly such that rotation of the motor assembly causes corresponding rotation of the propeller hub assembly. The retainer includes a pair of deflectable arms resiliently repositionable between a first position and a second position, for engagement and disengagement with the motor assembly, respectively. The arms are movable inwardly towards the rotation axis from the first position to the second position upon application of an external force and movable outwardly away from the rotation axis from the second position to the first position upon removal of the external force.
