This is a custom designed, 2-part adjustable camera mounting plate for the popular Vortex Racing Quad by Immersion RC. It mounts to the upper plate using the 4 standard anti-vibration rubber balls that came with the frame, replacing the standard carbon fiber flat mount. The center articulation is completed with a standard M3 screw and nut that you provide -- Nylon screw and nut recommended for lighter weight and better survivability.
Parts are shipped with tight fitting so that you can adjust them with light sanding for your preferred fit. This part will only fit in the Vortex 285
Camera angle is easily adjustable in the field depending on your flight style. I use a small velcro patch and strap to secure the camera to the mount, providing a light weight and strong attachment.
This design is strongly influenced by the one described at
this post in my blog.
