Rivabo propellers for model ships are assembled from various brass components, which are soldered by hand. Koch Metalworks b.v. have been producing the Rivabo propellers in their current form since 1984 according to strict quality requirements.
The propellers with diameters up to 75 mm are soldered with argentous tin and machine polished. Propellers with a diameter of 80 mm and above are soldered with silver and individually polished to give a high-gloss finish.
Rivabo propellers are ideal for both dynamic and static model ships. The combined action of the blade angle and the blade shape produces a high performance, while retaining the semi-classical character.
