Spinner, 3-Blade, 70mm, Aluminum/Plastic, White
Aeronaut # 726151

The high-quality 3-blade spinner for model aircraft was specially developed for demanding model pilots who value precision, smooth running, and optimal aerodynamics. As a central component in the propulsion system, the spinner contributes significantly to the overall performance and appearance of a model aircraft. Thanks to its exact manufacturing, this spinner ensures particularly precise concentricity, which significantly reduces vibrations. This not only protects the motor and bearings but also improves the efficiency and flight behavior of the entire model.

The base plate is made of robust aluminum and offers an ideal combination of stability and low weight. It ensures a secure and centered mounting of the propeller, even at higher speeds. The construction is complemented by a light yet durable spinner cap made of white ABS plastic. This material impresses with its dimensional stability and impact resistance, while also contributing to a balanced center of gravity. The simple, white surface also provides a versatile look that is excellent for both scale models and sporty aircraft.

A particular advantage of this spinner is its high compatibility. The 12-millimeter base bore, in conjunction with the supplied spacer rings, allows flexible adaptation to various motor shafts. This means the spinner can be easily used with shafts of 5, 6, 7, 8, and 10 millimeters in diameter. This versatility makes it an ideal solution for different models and propulsion configurations and greatly facilitates both installation and switching between different setups.

The spinner is specially designed for rigid 3-blade propellers and allows for a precise and secure mounting. The precise tuning of all components achieves optimal power transmission while minimizing unwanted imbalances. This leads to smoother running, lower noise development, and overall improved power delivery in flight.

In addition to mechanical precision, the spinner also offers aerodynamic advantages. Its aerodynamically optimized shape reduces air resistance and improves airflow in the propeller area. This increases the efficiency of the propulsion system, which is reflected in better thrust, more stable flight characteristics, and overall higher performance.
