U441 and U953 flak tower.

The pictures are of the basic tower shell and decks that we make. The tower shell is 455mm long. This one was built by Ken Griffin in Florida. It was designed to fit our existing OTW Type 7 boats so that owners can have a new submarine just simply by fitting the new tower , with no need to alter the central deck.

The tower will also be available as an addition to the existing OTW kit.

New and Improved Pump Controller

We have retired our standard solid state pump controller and introduced a whole new and more flexible model using the Arduino programmable micro-controller. This makes installation and troubleshooting a lot easier for the model builder. There are 4 test lights which indicate the status of water level probes, ballast pump operation, power levels and receiver signal loss.

The unit is fully waterproof and is a direct replacement for earlier ballast tank control units. There’s no need to change the wiring.

The pump output is short circuit proof (in the event of a stalled motor, for instance) and the input receiver is optically isolated.

The new unit is much more user-friendlier as well as being as accurate and reliable as before.

1/48th scale pump yet.

CD case gives an idea of size.

Made for a 1/48th scale Astute submarine model somewhere in Quebec Canada but also good for the 1/48th scale Sea wolf or any large submarine.
