Product Description

**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. Many of our dealers also offer installation services.

No more quarters and tape! Built specifically for the 3DR Solo gimbal, the DEAD WEIGHT balancing kit for Solo allows you to easily counterbalance lenses, filters and accessories mounted to your stock GoPro or Ribcage AIR modified cameras. Ultra dense metals were chosen for the counterweights to pack the most punch in a tiny size. Almost 2x heavier than lead! Our easy to use snap-on mounting system clips easily onto the back of your Solo gimbal. You can then snap our custom weights into any of the 10 clip positions. Just position the weights until your camera is balanced vertically and then slide the entire assembly left or right to balance it horizontally. A balanced gimbal means more efficient operation, less stress on the motors and of course butter smooth video.
