The mounting system allows you to mount different cameras into the same location in your fixed wing UAV. I use a Skywalker X8 and have two sockets mounted at each end of the fuselage looking down. I use a Nikon Coolpix L22 for RGB images and a Fujifilm A180 for UV and NIR images. Either camera can be mounted in each socket depending on the flight configuration required. I often just fly with only one camera in the front and have the choice of quickly fitting either. Both camera mounts accomodate micro servos to activate the shutter release. These are in service and work well.
I have printed a couple of lense protectors/shades to allow fitting clear lense protectors from the bottom of the fuselage but I am not happy with them yet. I will post them when completed.
