Align 425mm Carbon Fiber Flybarless Blue Blades - GAUI X4 II / NX4

●Use for Trex 500 EFL / Trex 500 Pro DFC / Trex 500L Dominator. Can be used for Trex 500E / Trex 500E Pro / Trex 500 ESP , GAUI X4 II / NX4

●The 425 carbon fiber blue main blades are designed specifically for extreme 3D flying, featuring both high agility and excellent stability characteristics. The blades have brand new airfoil design, coupled with new painted graphics. In addition, the blade rigidity has been increased for better anti-torsion characteristics during flight. The new airfoil design effectively minimizes turbulence at the blade tips, reducing blade noise and power loss, while adding efficiency.
