The SR-1 Quad Plane


The SR-1 Quad Plane is a complete Unmanned Aerial System (UAS) solution optimized for long range monitoring and large area mapping missions.  The SR-1 combines the hover and Vertical Takeoff and Landing (VTOL) capabilities of a multicopter with the fast and efficient forward flight capabilities of an airplane into one practical platform.  It carries a downward-facing photo camera and a dome video camera, and has a large payload capacity to allow for a variety of on-board instrumentation options.
