SpinBlades 2-blade semi-symmetrical, 325mm long, # 1842325

The semi-symmetrical blades are now the third generation of this product line and have been continuously improved. For example, the desire for even more stable flight characteristics has been implemented without changing the familiar gliding flight feeling of our semi-symmetrical blades. New manufacturing methods allowed the profile to be further optimized and the transition at the leading edge to be adapted to the airflow. This leads to a further increase in efficiency.
These aerodynamic changes have further increased flight times. These rotor blades are particularly recommended for beginners, advanced pilots who do not want to fly 3D, or scale pilots who want to reduce their system speed. The combination of the defined flex behavior of the rotor blade, the load-bearing profile, and the extremely far outside blade center of gravity allows the system speed to be significantly reduced, which reduces stress on the entire system. This reduces wear and increases flight time.
The usual wobbling or unstable flight behavior with these blades only occurs at a significantly lower speed than with conventional blades. Of course, these blades are also no longer drilled at the blade root. The bore for the bolt of the blade grip is realized by the mold. This has the advantage that the surrounding fibers are no longer destroyed, which ensures significantly higher strength with the same material usage. To highlight the high-quality materials without losing the unmistakable SpinBlades look, we use visible carbon fiber elements and high-gloss white in the design. Of course, these blades are also finely balanced as usual (tolerance 0.05g).

These 325mm blades are ideally suited for a Gaui X3, Trex 450, MiniTitan, Blade 450X or similar helicopters of this size (450 class).
