Hobbyking sells a kit to relocate the lense on a mobius cam and it comes with a new frame too, so basically it makes it the shape of a gopro. That way it can be mounted in any gimbal. It was still lighter than a gopro too.
I broke down and bought a gopro 3 black for the better video quality along with fpv at the same time and compatibility with the walkera g2d plastic. I'm happy but my wallet isnt...lol
Great find dtitus! I love solutions to unanswered questions...
It's not all that expensive and looks pretty neat. As an added bonus for us tinkerers you'd get to take something apart and put it back together again. THAT'S a fringe benefit!

Congrats on the GoPro! I'll tell ya, you really can't hardly beat those Plastic G2D Walkera's for the price!
