I assume the camera system comes with an stc. It probably affects a lot of things but those could be characterized and provided with stc. I assume this camera system costs well into six figures so some test pilot time to provide info wouldnt be impossible to budget for.That got me even more curious. After digging around I found this: https://www.soloy.com/uploads/9/0/6/9/90692509/s2060a-wing-mount-camera-pohs.r2.uncontrolled.pdf
-Max airspeed limited to 140kts (small loss from 151-161kts)
-Flaps limited to 20 degrees (limited from 30-40)
-Requires aileron trim tabs to be installed
-(Edit) Oh and autopilot not permitted during IFR. I suppose that's not a terrible "problem" as your camera's not going to be much good during IFR anyway
Emergency procedures are not affected.
Edit:
Now that I've read the link, it definitely comes with an stc.
