The US Navy Ocean Fleet Tug „Powhatan Class“ is now available in 1:144 scale. The kit is RC ready to be operated through twin propellers, working rudders and a bow thruster. The parts are derived from the 1:200 scale model but are adapted to 1:144 scale with adapted wall sizes etc.
My larger size GillJet drive (azimuth thruster / pump jet / invisible Schottel drive) is available for larger RC boats, using a 20mm impeller drive that can rotate 360 degrees vertically to provide both propulsion and control: http://shpws.me/Rbxm
The model can be equipped for radio control (RC) via four channels: two 16mm props directly driven via N20 motors each in kort nozzles, twin rudders and a bow thruster. Additional function can be added. Parts needed to build a static display model are included, too. A display stand will be available shortly.
To complete the Thetis class model (Klasse 420, German navy submarine hunter, later Greek navy gunboat), I added a set of static propellers for those who do not want to build an RC model but a model for static display: http://shpws.me/QJ8v
