Do it yourself if you like to tinker! Install Back-Bone’s custom, all aluminum Ribcage AIR mod kit on any GoPro Hero4 Silver or Black (not included). Your camera will then be able to take micro M12, CS-Mount or C-Mount lenses. Designed for small UAVs and GoPro stabilizers the Ribcage AIR was built specifically to fit the 3DR Solo gimbal! Our premium machined aluminum plates are 50% lighter than our standard Ribcage Hero4 Mod. Detailed step by step video instructions. Note: CS and C-Mount lenses are not recommended for use on Solo or any other small GoPro gimbal.

**Please note that this product is not necessarily for everybody. It requires you to take apart and re-assemble your camera which will void the manufacturer’s warranty. Back-bone has no control over the end user’s skill level and cannot be held responsible for accidental damage. We recommend that you view the installation video on our support page before you buy to make sure this is right for you. If you don’t feel comfortable performing the installation yourself we also offer Hero4 Silver and Black cameras that have already been modified and tested. Contact us to inquire about our installation services if you already own a compatible camera.

Designed from the ground up to be as light as possible, the new Ribcage AIR Mod Kit for for GoPro Hero4 is perfect for any aerial platform but we designed it specifically with the 3DR Solo in mind. Benefit to the max from 3DR’s unique camera control – only now with interchangeable lenses to get exactly the look you want. Many distortion free wide angle lenses are available. Use M12 lenses under 10 grams on the Solo or most other small GoPro handheld or aerial gimbals*. Use CS, C-mount or larger lenses on bigger aerial platforms and gimbals. You can even fly with some great vintage D-Mount and Bolex lenses.
All of the lens mounting rings are easily removable for filter replacement and sensor cleaning. Combine up to two custom filters in camera at the same time. You won’t need filters for all your different lenses anymore, just for the camera! Now you can use ND, cold mirror, NDVI and other custom wavelength filters with your M12 lenses, or lenses that have no filter threads on the front. Choose from our line of tried and tested high resolution lenses, or use your own. Browse through our library of high resolution lenses to find the right lens for your needs!
* M12 lenses under 10 grams recommended for Solo and other GoPro gimbals. Back-Bone’s ‘DEAD WEIGHT’ gimbal balancing kit for Solo recommended for best results and to reduce wear on the gimbal. CS and C-Mount lens types are too heavy for GoPro based gimbals. These are recommended only for larger platforms.

** CS and C-Mount lenses are too heavy for Solo or other GoPro gimbals, use them only with a larger aircraft or gimbal. Stick to M12 lenses 10 grams and under as a general rule for GoPro gimbals. Our ‘DEAD WEIGHT’ gimbal balancing kit for Solo is recommended.

Please note that the slim Hero4 waterproof housing is included as it comes with the original camera. For waterproof use we recommend picking up the extended backdoor for the case and to use our 7.5mm Low Profile lens with the standard M12 mount. You can cut a piece of foam to fill the small space behind the camera, or put in the protective plastic cap that comes with the camera; it just so happens to be exactly the right thickness. When using our 7.5mm M12 lens you can either remove the IR-cut filter or reconfigure the camera with the supplied rubber O-ring instead of the plastic spacer to achieve proper focus.
