We have an Horizon Hobby Inductrix 200 quadcopter which comes with a fairly low quality FPV camera.

We replaced the original FPV camera with a Horizon Mini with a cloverleaf mounted in the center top. It has a channel button on the top and a channel display on the rear, as well as a top-rear power line.

I couldn't find a drop-in replacement swivel case with openings for these items so I made my own.
