This is a set of Align 550 3G Carbon Fiber Blades. Align's 550 3G main blades are designed specifically for extreme 3D flying, featuring both high agility and excellent stability characteristics. The blades have a redesigned airfoil and painted graphics. Additionally, the blades rigidity has been increased for better anti-torsion characteristics during flight. The airfoil design effectively minimizes turbulence at the blade tips, reducing blade noise and power loss.
