Balancing arm for the Chinese gimbal (Xiaomi, GoPro)

The arm allows you to balance the sports camera (like Xiaomi or GoPro) in a simple, cheap, Chinese gimbal.
Tested with 2 axial gimbal, but it can work with a 3 axial model.

After balancing, the gimbal becomes more stable and consumes noticeably less power.

Perfect and tested for Xiaomi Mijia Camera Mini and GoPro Hero 4 Black.
