6-Blade Brass Ship Propellers – smooth, low-cavitation, authentic

The 6-blade brass ship propellers at Ship Models Shop are designed for models that demand smooth operation and cavitation control. They are ideal for submarines, aircraft carrier replicas, and other large functional models operating under heavy load.

Advantages

• Low cavitation – six blades distribute pressure evenly, minimizing bubble formation

• Exceptionally smooth running – stable thrust with less vibration

• Reliable under load – consistent performance even in demanding conditions

• Durable & scale-accurate – brass ensures long life and realistic looks

Technical Features

• Material: brass

• Blades: 6, often skewed for added smoothness

• Sizes: typically 40–70 mm diameter

• Thread: usually M4, available in right- and left-hand versions

• Applications: models sensitive to cavitation or high hydrodynamic load

Buying Guide

1. Model type: submarines, aircraft carriers, and large-scale models benefit most

2. Diameter: choose according to hull size and motor output

3. Pitch: adjust to motor torque and RPM

4. Thread & rotation: ensure exact shaft fit; use counter-rotating props for twin drives

Conclusion

6-blade brass propellers combine low cavitation, smooth running, and authentic scale appearance – making them the top choice for advanced RC submarines, carriers, and large functional vessels.
