Spinner, 3-Blade, 51mm, Aluminum/Plastic, White
Aeronaut # 726121

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 significantly contributes to the overall performance and appearance of a model aircraft. Thanks to its precise manufacturing, this spinner ensures particularly accurate concentricity, which significantly reduces vibrations. This not only protects the motor and bearings but also improves the efficiency and flight characteristics of the entire model.

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

A particular advantage of this spinner lies in its high compatibility. The 12-millimeter bore, in conjunction with the included spacer rings, allows for 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 drive configurations, significantly simplifying both installation and switching between different setups.

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

In addition to mechanical precision, the spinner also offers aerodynamic advantages. Its streamlined shape reduces air resistance and improves airflow in the propeller area. This increases drive efficiency, which translates into better thrust, more stable flight characteristics, and overall higher performance.
