KDE Direct carbon fiber propeller blades are constructed of true carbon fibre 3K materials and now available for commercial and industrial applications.  All propellers are dynamically balanced and provided in matched pairs, so simply install the blades and go fly - no need for secondary balancing

Includes:

• Three (3) KDE Direct Propeller Blades, 27.5" x 8.9, Triple-Edition (CW matched set)
• Three (3) KDE Direct Propeller Blades, 27.5" x 8.9, Triple-Edition (CCW matched set)
• Two (2) triple blades folding hubs

Weight:
43.2 g/blade (design is FEA optimized for maximum strength and minimum weight)

Note: propeller blades are dynamically balanced matched pairs, for smooth and vibration-free flight operation.  Blades cannot be intermixed between pairs - make sure to keep organized as matched blades to prevent balance related concerns.  If a single blade is damaged during operation, make sure to replace the propeller blade pair (CW or CCW)
