Abstract: A motor assembly that includes a motor having a motor casing, a rotatable shaft extending from said motor casing to a shaft length and a hub coupled to said rotatable shaft, the hub having a circumferential skid surface disposed immediately proximal to the motor casing and having a channel configured to seat a propeller, when a propeller is present, wherein a bending moment applied to the shaft through the hub results in the circumferential skid surface contacting said motor casing.

Abstract: A system, method, and apparatus for remotely controlled or even autonomous drone positioning control includes a drone, positioning control subsystem, subcontroller, positional or inertial sensor, processor, image sensor, and ground control device, and is configured to i) ascertain a geographical area having a geofence, ii) track at least one subject and an associated physical or digital marker within the geographical area, iii) recognize and process at least one marker geofence, iv) execute at least one positioning plan data set having at least one positioning path, and v) fly the drone per the data sets and paths without crossing a geofence or colliding with any obstacle. The present invention may also be configured to execute one or more commands that cause the drone to switch its position or path relative to priority or sequence-oriented commands, or to move the drone within a certain distance from the marker.
