An HVAC line set duct system includes a line set duct with a channel clip. The duct houses an HVAC line set and includes a channel connector for slidably securing the channel clips along the length of the line set duct. The channel clips have collars that engage tie wraps that in turn secure the HVAC line set to the line set duct. The channel clips are installed onto the line set channel connector by exerting a force perpendicular to the length of the line set duct so that the channel clips snap onto the channel connector and slide along the channel connector.

Multi-wing hovering and gliding flapping Micro Air Vehicles ('MAV') are disclosed. The MAV can have independent wing control to provide enhance energy efficiency and high maneuverability. Power to each wing can be controlled separately by varying the amplitude of the wing flapping, the frequency of the wing flapping, or both. The flapping frequency can be controlled such that it is at or near the natural frequency of the wings for improved energy efficiency. The wings can be controlled by a gear train, coil-magnet arrangement or many other actuation systems that enable variable frequency flapping, variable amplitude flapping, or a combination of both. The gear train mechanism provides gyroscopic stability during flight. The wing flapping can include a rotation, or feathering motion, for improved efficiency. The wings can be transitioned between flapping flight and fixed wing flight to enable gliding and hovering in a single configuration.
