Has anyone mounted a Mobius (or similar camera) lens thru the switchband of their AV bay, and also managed to get the lens pointed downward? I'm trying to do that on a 54mm rocket with a 1" wide switchband.
On another note I have considered making these parts available for sale if there is enough interest.
I have done this on both of my high power rockets. I made forms for creating a FG/CF aerodynamic shroud for the camera lens, the form is also used to help glass the shroud to the tube. This ends up with an extremely strong setup, my first rocket came in ballistic and buried the camera 4ft down and there was zero damage to the shroud or camera. The first rocket was a little more complex, it was a 54mm with ttw canards that the camera had to fit around. There are some small holes drilled for access to the camera buttons and light which works but can be a pain. The camera was also rotated 90 degrees from the typical orientation and tilted away from the rocket slightly, this allowed me to use the wide angle to capture the airframe and flame at the very bottom of the frame while still seeing all the way to the horizon. The result can be seen here:

My second rocket is a 4" rocket with the camera mounted near the nose. This build had a lot more room to have a much simpler bolt in sled and the camera is powered off of my av bay with a tiny 5v regulator through the UBS port. By setting up the camera to turn on when it receives external power and start recording on power up (available on the authentic 808 cameras) I can be sure that as long as my av bay is beeping my camera is recording. By powering it externally this also solve the problem of the junky batteries, on one of my early flights of my first rocket I failed to get a recording because a bad battery only had enough power to record the first 5 minutes waiting on the pad. The results of that camera setup can be seen here:

Thanks for the reply. Do you know of any threads or any other source of info for building and using mirrors/periscopes to do this? I found one thread on here from 2006 but it's mostly about where to buy the mirrors.Have you thought about making a periscope for it? Making first surface mirrors isn't difficult, and you can keep the camera completely inside the AV bay.

I have been doing camera holes through both avbay and airframe for some time now. It requires some degree of precision, but not too bad. Also since the material to peer through is effectively thicker, making it more difficult to get a full frame of view outside the rocket. Still, it gives me decent footage and hardly impacts performance.

I have a 3d printer and am willing to collaborate with anyone to come up with a solution. I have a mobuis camera with an extension cable. I have been planning on removing the camera electronics from the case and integrating the board on my av bay sled and printing a mount for the CCD/lens that attaches to the switch band.
