DU-BRO Drone & Quadcopter Prop Balancer – Precision Prop Balancing System

The DU-BRO Drone / Quadcopter Prop Balancer & Shafts make it easy to balance your drone props for smoother flights and clearer video. Properly balanced props reduce vibration, improve motor life, and help your drone fly more stable. Whether you fly a camera drone, a racing quad, or a small hobby multirotor, this tool helps you get better performance.

The balancer uses aluminum wheels that spin with almost no friction, so even tiny imbalances are easy to see. It also includes simple instructions, making it easy for both beginners and experienced pilots to use.

Because different drones use different prop hubs, DU-BRO offers several CNC-machined aluminum balancing shafts. These shafts come in threaded and friction-fit styles, so you can choose the one that matches your drone’s prop design. Some DJI drones use special quick-release hubs, so DU-BRO created friction-fit shafts that slide securely into these props without causing damage.

All shafts work with the DU-BRO #499 or #3396 Tru-Spin Prop Balancer, both known for their smooth, precise action.
