In a general aspect, a handheld controller device includes a housing and a trigger assembly. The housing is configured to be held in the hands of a user. The trigger assembly includes a pair of triggers extending outward from a side of the handheld controller device and configured to move along respective trigger paths. The trigger assembly also includes a guide and coupling assemblies. The guide assembly is disposed inside the housing and includes, for each trigger, a channel that extends at least partially along the trigger path of the trigger. The coupling assembly is disposed inside the housing and is connected to the pair of triggers. The coupling assembly is configured to transfer motion between the pair of triggers such that, when one trigger moves towards the housing along its respective trigger path, the coupling assembly moves the other trigger away from the housing along its trigger path.

There is provided a composite air vehicle system including: a first air vehicle capable of independent aerodynamic flight; a second air vehicle capable of independent aerodynamic flight; and at least one connector element configured for reversibly interconnecting the first air vehicle and the second air vehicle in tandem arrangement to provide a composite air vehicle capable of aerodynamic flight. The composite air vehicle system is configured for enabling at least in-flight separation of composite air vehicle into the first air vehicle and second air vehicle, and for enabling each one of the first air vehicle and said second air vehicle to operate independently of one another.

In some examples, an apparatus comprises a surface and at least one flange extending from the surface. The fitting is operable to rotate from a first angular position to a second angular position based on contact between the at least one flange and a fastener and a torque applied to the fastener. In the first angular position, a gap separates the at least one flange from a barrier. In the second angular position, the at least one flange prevents rotation of the fastener based on contact between the barrier and the at least one flange. In some embodiments, the at least one flange comprises a plurality of flanges.

An unmanned vehicle including a body and a frame structure extending from the body and supporting a plurality of propeller assemblies, each propeller assembly including at least one propeller and a corresponding motor with the motor housed in a watertight housing or coated and made corrosion resistant. The propellers comprise a first subset of propellers of the propeller assemblies and a second subset of propellers of the propeller assemblies which rotate in a plane positioned below a plane in which the first subset of propellers rotate, wherein said first and second subset of propellers are configured for independent operation of one another as the vehicle transitions from an air medium to a water medium.

Implementations of an unmanned aerial vehicle (UAV) provided with detachable motor arms are provided. In this way, the UAV may be conveniently stored and transported, rapidly assembled in the field, and repaired in the event of a crash. Also, the motor arms are configured to separate from the fuselage of the UAV upon crashing into the ground and/or another object. In this way, damage to the motors arms and/or the fuselage of the UAV may be minimized or prevented. An example UAV comprises a fuselage having two motor arms detachably secured thereto, each motor arm is detachably secured to the fuselage by two mechanical connectors (or fuses) and comprises a tube having a rotary wing propulsion system on each end thereof. The mechanical connectors securing each motor arm to the fuselage of the UAV are configured to facilitate the separation of the motor arm from the fuselage during a crash.

An example method of manufacturing a wing includes providing a wing frame. The wing frame includes a primary spar, a drag spar, a plurality of transverse frame elements having at least one spar joiner, and a plurality of mounting elements. The primary spar is coupled to the drag spar via the at least one spar joiner. The method further includes placing the wing frame into a mold, wherein the mold defines a shape of the wing. The method also includes injecting the mold with an air-filled matrix material, such that the air-filled matrix material substantially encases the wing frame and fills the defined shape of the wing, and such that the plurality of transverse frame elements provide torsional rigidity to the wing.
