That's excellent, and I agree that minimal upgrading would be awesome, but I'm going to be focusing strictly on making an M12x0.5 conversion due to keeping things universal on my end. The way I intend to do it, it's not so much a challenge to make it work as it will be to make it work and be light and reasonably small for AV uses. My goal is to make a version of the camera that covers all the things I do already, but also covers my latest love affair with RC flight. I feel that I can make it happen and still keep things reasonable for that, but I know there will be hurdles. I'm definitely going to be brushing up on my plastic milling skills for starters, lol. I think this is going to be fun, and hopefully it will be my best work ever. :-)
That said, I do want to look deeper into what you found, because there's great potential there for a superlight yet improved version of the camera.
Edit: I forgot to mention - it looks like I may be able to use a single lipo cell ripped from a damaged E-Sky Big Lama 800mAH 3S pack in my mod. The cells measure just right for the case I intend to use, and would make a pretty interesting upgrade from the 250mAH stock cell.
