This is a FPV mount for the FMS PA-18 1300mm RC plane.
The mount can replace the original foam part and also works with the spring loaded snap axle for a tight and secure fit.
It is made for the DJI Air Unit Lite with the Nebula Pro camera.
However it will most likely also work with any 19mm FPV camera and 20mm by 20mm VTX mounting holes. Only the VTX antenna mount might not fit if not used with the Air Unit Lite.
