Biela carbon fiber propellers are made exclusively from high-quality raw materials. Particularly precise shapes and expert manufacturing enable very accurate balancing, resulting in an exceptional running culture of the motor. The front side is white with red blade tips, while the back side is black, as is often the case with original aircraft. Therefore, they are very true to scale! Semi-scale props have been specifically designed for certain aircraft models and give the model the final touch for a perfect appearance. The "Sport" series has been developed specifically for the needs of aerobatics and offers approximately 10% better efficiency while simultaneously reducing noise levels.
