Do you leave it in place or install it/remove it every time? I'm asking because it seems (with no experience at all) that the changing of temps would have it come loose frequently. I don't want to damage the camera or scratch any interior finishes ... I don't plan on moving it often (if ever) and I know if I don't have to fuss with mounting it every flight I'll use it more often.
I have used it exactly once so I'm not a good data point yet. I do plan to take it off each time though. I didn't explore many other mounting options as this was just a quick solution that seemed to work.
Using a suction mount, I can mount a GoPro Hero 6 and a fan to keep it cool. Both are plugged in to my dual USB power socket. The suction mount has been in place for more than a year, has not fallen off once, baked in the sun and nocanopy deformation is visible. A twin camera mount lets me have either two cameras (like the GoPro Hero 6 and full 360 video GoPro Fusion) or a camera and the fan. I keep all cameras encased in a white latex cover to help reflect the light from our dear sun.
Here's a closer pic of the backside when I used a different source of power prior to the socket shown above. It shows the audio cable which carries audio from the GMA-245 intercom (I prefer the direct connection rather than via Bluetooth) and the twisted pair that carriers power to the dual USB socket.
