Abstract
Systems, devices, and methods including an unmanned aerial vehicle (UAV); one or more inner wing panels of the UAV; one or more outer wing panels of the UAV; at least one inboard propeller attached to at least one engine disposed on the one or more inner wing panels; at least one tip propeller attached to at least one engine disposed on the one or more outer wing panels; at least one microcontroller configured to: determine an angular position of the at least one inboard propeller; and send a signal to halt rotation of the at least one inboard propeller such that the at least one inboard propeller is held in an attitude that provides for clearance of the propeller blade to the ground upon landing.

A system comprising:
- at least one microcontroller in communication with at least one engine,
- wherein the at least one microcontroller is configured to:
- determine an angular position of at least one inboard propeller attached to the at least one engine;
- and
- send a signal to halt rotation of the at least one inboard propeller such that the at least one inboard propeller is held in an attitude that provides for clearance of a propeller blade to a ground upon landing.
A method comprising:
- determining, by at least one microcontroller in communication with at least one engine, an angular position of at least one inboard propeller connected to the at least one engine;
- and
- sending, by the at least one microcontroller, a signal to halt rotation of the at least one inboard propeller such that the at least one inboard propeller is held in an attitude that provides for clearance of a propeller blade to a ground upon landing.
A system comprising:
- at least one microcontroller in communication with at least one engine,
- wherein at least one inboard propeller is attached to the at least one engine, and wherein the at least one microcontroller is configured to:
- determine an angular position of the at least one inboard propeller;
- and
- send a signal to the at least one inboard propeller such that the at least one inboard propeller is held in an attitude that provides for clearance of a propeller blade to a surface.
