APC propellers have been popular for years and are developed based on the latest findings and manufactured using state-of-the-art machines. They are significantly quieter than comparable propellers due to their unique blade shape and can achieve very high efficiencies with proper tuning. A wide range of different sizes and pitches is available for optimal adaptation. Recent developments include the APC Slow and Electric Props, which are even lighter and specifically designed for the needs of electric models and their Reynolds number range. These propellers come with adapters for standard shaft diameters. LP08041SF.
