The “7-Blade Brass Ship Propellers” category at Ship Models Shop offers propellers designed for silent running and efficient thrust delivery. With seven blades, the flow is smoother, vibration is minimized, and noise is reduced. This makes them an excellent choice not only for scale surface vessels but also especially for RC submarines, where stealth and smooth operation are essential.
Ultra-quiet operation – minimized noise, ideal for submarine use
Stable thrust – smooth propulsion above and below the surface
Efficient flow – reduced turbulence, improved energy efficiency
Durable & authentic – brass construction for longevity and scale realism
Precision design – stable running under demanding conditions
Material: brass
Blade count: 7, precision-engineered for smoothness
Size range: approx. 30–60 mm for different scales
Thread: e.g. M3, M4 – fits common shafts
Rotation: right-hand standard; left-hand available upon request
Model type: submarines and scale models benefit the most from 7-blade design
Diameter: select according to hull size and motor performance
Pitch: adjust for thrust vs speed balance
Thread & fit: ensure proper shaft match for vibration-free running
7-blade brass propellers combine quiet performance, efficient propulsion, and a scale-accurate look. They are particularly well-suited for RC submarines, where smooth, silent running is crucial.
