In the photo below you can see a rectangular opening on the upper center and a triangle that has been raised. The rectangle is a cutout for your FPV camera. When you set the Alta back in the case the 'front' points to the left so that the camera has clearance as the Alta sits in the case. The triangle, and you can see the dents, is where the boom with the video transmitter is mounted. If you transmitter extends below the bottom of the boom simply remove or carve a hole for the bottom so that you don't pinch and cables. The piece is not glued down and pops out with a little finesse.
