These instructions enable you to see what is involved in building a working radio controlled model of the Offshore Support Vessel Viking Neptun at a scale of 1/144 from the stl files available for purchase from here https://www.cgtrader.com/3d-print-models/hobby-diy/robotics/radio-controlled-offshore-support-vessel-viking-neptun-ship-boat . At this scale the model is 1000mm long and 240mm wide. The files include a working bowthruster for added realism.

The original ship was built in Norway in 2014 and is presently used as a Cable layer, and this model includes a representation of that cable laying equipment.

The model is printed in about 100 parts using a filament printer throughout. The buildplate size needs to be 300mm square.

The completed model works very well as a radio controlled model with a good stable performance on the water even in windy conditions, with sharp turning circle. The included bowthruster which is simple to build adds interest and realism to the model.
