The SRS-Sentinel_XQ42 is almost identical to the XQ41 however in this build the IR camera is mounted underneath the Thermal camera to allow it to point down more. The tri blade rotors have been substituted here for 11" bi blades at 5.5 pitch to allow for a longer, more efficient hover hang time.

After so many successful flights using Waypoints and "Return to Home" with a connected Mission Planner laptop, the design team concluded that the IR camera should be better positioned for "Security Camera" angles rather than as a flying instrument.
