Black Belt 205 Main rotor blade for e.g. T-Rex 250, Gaui 200

In our new blade series, the Black Belts, our years of experience, scientifically proven wind tunnel results and pilot preferences have been taken into account and implemented. The profile of the blade corresponds to today's upscale engine performance standards.

The blade is adapted to the rotational speed of the rotor at every point. This results in a significant increase in efficiency (up to 30% according to wind tunnel data), which is noticeable in better response to cyclic inputs, smoother stopping behavior and much faster acceleration.

Additionally, these blades are no longer drilled at the blade connection: The hole for the blade mounting bolt is implemented through the mold, which means the fiber is no longer destroyed. This ensures significantly higher strength with the same amount of material. By using a new type of carbon fiber, which ensures better fiber coverage, the strength has been increased once again.

For safety reasons, the number of Kevlar fibers previously used has been multiplied in order to keep pace with the trend toward ever higher speeds. The advantage of Kevlar is clearly that this fiber bonds completely with the resin. This is not ensured with conventional materials such as wire, since the wire is always a foreign body within the fiber composite.

In the design, attention was paid to the best possible attitude recognition in all weather conditions, but without losing the distinctive SpinBlades look. This was realized by a combination of visible carbon fiber and highly brilliant white fields.

Furthermore, as with all of our blades, a strong focus was placed on balancing, ensuring a tolerance of less than 0.05g.

These blades fit perfectly on a Gaui Hurrican 200, TRex 250 or similar helicopters of this size.
