TRIM PUMPS: Six flexible impeller pumps of the windscreen variety, were used to pump water into and out of the vessel, and to distribute the onboard water to four tanks in the hulls such as to achieve level running.

A number of channels of the radio controls were needed operate the pumping system.  In fact, so many it would mean a very expensive radio setup.  To avoid this 6 channel and 3 channel Futaba sets were fused together to form a nine channel set.

Amerang of Worthing, the distributors of HiTec radio controls in this country, heard o four plight and in consideration of our tight budget, supplied the sets at a special price.

FLOTATION: 

The same laws of physics apply to the scale model as to the full size boat. This is useful for a number of reasons. It is possible to develop a boat and try radical ideas that a boat yard could not afford in real life. In other words you can experiment for a fraction of the cost, by testing small. In fact a small wooden test tank was constructed to allow the model to be trimmed before moving to open water.

BUDGET: It was decided not to use fancy materials to save cost. The budget for the model and a display stand was set at £3,000. This sounds a lot, but in fact the price of radio gear and other modeling equipment saw a chunk of the budget disappear immediately. Fortunately, our friendly local model shop always gave a discount (thanks Dave). The importers of our Hitec radio equipment also gave a substantial discount (thanks Amerang). As did Hunter Systems (thanks Graham).
