I’ve been filming my flights for some time. Originally, I attached a camera to a suction mount but it fell shortly after I started the engine. I tried it on another flight with the same result. I realized that even if I replaced the suction mount, I’d always being worrying about it falling. So I turned to the clamp mounts. Here are the ones I use:
The SafeRacer clamp is inexpensive and relatively versatile.
I often use this clamp with an iPhone 5, which requires an adapter: http://www.rakuten.com/SR/SearchResults.aspx?mfgid=391307
The Mini Cardellini with Noga Arm aka Israeli Arm is the Cadillac of clamps.
