A must for making rock solid, stable video  

The DU-BRO Drone/Quadcopter prop balancer's aluminum wheels turn virtually friction free for precision accuracy. The Du-Bro Tru-Spin Prop Balancer will balance drone props of all sizes and weights.  Each balancer comes complete with easy to follow assembly and prop balancing instructions. A truly precision instrument built for the modeler who expects the very best.

Specially designed balancing shaft with left and right hand threads. For Drone/Quadcopter Props. Balancing shaft is made of CNC machined aircraft aluminum for a precision balance.  

Some very popular drone models such as the DJI Phantom 4 include unique prop hub that will not work with traditional balancers. DU-BRO has a solution for these props with our centerless ground Friction-Fit prop balancing shafts that works with the popular #499 or #3396 Tru-Spin Prop Balancer.

Made in USA

DU-BRO Drone prop shafts are sold separately and you need to purchase either a #499 or #3396 which have the balancer included to use your shaft.  To see what drone models work with the specific shafts, see below.
