The importance and value of precisely balanced props:
Balanced props on multi rotors are very important for two reasons.  Out of balance props are hard on the motors and make them work harder.  Also, out of balance props induce vibrations in the airframe that manifest themselves through the airframe down to camera equipment such as the GoPro® camera.  This causes instability and a “jello” effect in the final image capture.  If you are a videographer and/or photographer using the DJI Phantom for image capture, propellers balanced with the Speedy™ Prop Balancer are a “must have” in your tool box.

There are two main criteria to accurately balancing propellers - an accurately machined Prop Rod and a mechanically accurate Balance Base.

The Prop Rod is made from a rod of aircraft grade aluminum that is precision threaded on a $150,000 CNC lathe to a tolerance of .0005” (1/2 thousandths!)  On the CNC lathe the rod is held in place with a friction collet to protect the extra smooth surface of the rod. The left hand thread for the black nosed CCW props is indicated by the 3mm shallow channel milled near the end of the threads and is easily visible. 


The Prop Balancer Unit is produced on a $40,000 laser CNC laser cutting system from 1/8” thick acrylic for both the base and the vertical pillars.  The key to the design of the base is that all surfaces are “square with the world” with both pillars being precisely aligned with the base at 90º and the two support rods front and back being precisely parallel to the base.  This design utilizes only two contact points on precision steel .047” rods unlike the DU-BRO and other devices that can depend on up to eight contact points and can possibly introduce undesirable variables due to friction at each contact point.  The Speedy® Prop Balancer eliminates the “hesitation” in rotation in other devices rather than the smooth silky movements with the Speedy™ Prop Balancer.
