No, all KDE Direct Propeller Blades come dynamically-balanced and provided in matched-pairs or sets, so simply install the blades and go fly - no need for secondary balancing or other headaches. Self-balancing can potentially damage the propeller blade and/or weaken the structure, leading to an unsafe operation and/or making it unusable in flight operations.
How do I keep the Propeller Blades organized as balanced pairs/sets?
The Propeller Blade product comes with a custom, KDE Direct decal sheet contained within the packaging. The decals are self-adhesive, so select a different color for each propeller pair/set to keep them organized. Best to perform this upon initial receipt of the Propeller Blades, matching the pairs/sets as provided in the original product packaging from our production facility.
If I crash, can I still use the Propeller Blade?
Unfortunately, no. Any damage to the propeller blade, such as surface imperfections or internal cracks outside the view of the human eye caused from crash impact, can lead to unsafe flying. If a single-blade is damaged during operation, make sure to replace the propeller blade pair or set (CW or CCW).
Can I save extra propellers if I crash and use them later?
Unfortunately, no. All KDE Direct Propeller Blades are dynamically balanced at our production facility, so each set is perfectly matched for smooth and vibration-free operation. The use of a static-balancing propeller stand is non-ideal, as both static and dynamic balancing methods are needed to produce a high-quality Propeller Blade. At KDE Direct, specialized CNC equipment is used in manufacturing for this detailed operation.
