Another project that I've been working on at the same time as the Universal Camera mount is a naturally complementing upgrade for the Phantom 2; foldable leg extensions. I've found a backpack for myself that fits the Phantom 2 perfectly, but the height of the stock legs isn't enough for my experiments, so I had to think laterally about producing legs that were both longer, and more compact in my backpack. After a few failed prototypes, including none that I have installed, I managed to arrive at a very simple design, that allows the stock compass to be fitted, for the feet to adjust to the surface of the ground they land on and for the hips to be stiff and simple.

I've been dropping the prototypes from ~1.5 meters with a 1.25kg weight and the last, less robust version lost 3 legs. My hope is that the one that is currently printing will survive the fall ... and it should be noted that the PLA I am using in test prints is significantly more brittle than the Nylon plastic that Shapeways sells! Let me know if you have any thoughts or feature requests for this product.
