Summary Simple mount adapter to attach an MD80 spy cam to an MJX X400 quadcopter. The design should allow an "ear bud" stalk to be used as a pin, I used philips screw drivers to splay the ends of the pin and a soldering iron to make a notch so it can't fall out. The idea is that the camera should pivot under its own weight after take off. https://www.youtube.com/watch?v=AAXnhmKaazA&feature= The mount screws into the same fastening locations as the C400x cameras that are normally used with the MJX X400. I did also remove the internal battery from the MD80 and fashion a connector that connects it directly to the C4005 power source, but it turns out the voltage drop when under power is enough to cause the MD80 to powerdown, so I don't recommend wasting your time trying this, I did not test the C4002 socket to see if it might have better performance.

The pin is normally a tight fit in the camera itself.
