Abstract: A radio-controlled (RC) aircraft has a wing lock and disconnect mechanism. The RC aircraft has a structural member and a wing that disconnects from a fuselage. The RC aircraft has a lock mechanism, a wing structural member recess, a fuselage structural member recess, a lock recess, and an aperture. The lock mechanism couples to the wing and is adapted to fit within the lock recess of the fuselage. The wing structural member receives the structural member. The fuselage structural members recess corresponds to the wing structural member recess. The lock recess receives the lock mechanism. The wing disconnects from the fuselage by unlocking the lock mechanism. The structural member fits within the wing structural member recess and the fuselage structural member recess.

Abstract: Example embodiments include an aerial vehicle configured to establish a geo-fence. In particular, an aerial vehicle may include an inertial measurement unit, a GPS sensor, and vehicle controller circuitry that works together to establish a geo-fence based on an initial location. In an example embodiment, the aerial vehicle may establish a rectangular geo-fence and a wind direction based on received angular data, acceleration data, and location data. The rectangular geo-fence may include a minimum fence height, a maximum fence height, a fence length, and a fence width.

Abstract: Remote control aircraft may benefit from airframes with components that are easy to connect and disconnect. For example, during repair, storage, or transport, it is beneficial to disconnect a wing from a fuselage of a remote controlled aircraft. Systems and methods for connecting and disconnecting airframe components are described herein. For example, a snap-fit mechanism is used in some instances to provide a solid connection during operation or flight, and also to quickly and easily disconnect components at various times, such as during repair, storage, or transport. The snap-fit mechanism allows for a quick disconnect without the use of tools and without causing any loose parts.
