The latest model proved to have a few different challenges. A publisher wanted a model plan that would be able to be built from the plan or by using a "wood pack" containing precut parts. As the publication was not to be just targetted at people who build model boats, something with wide appeal was needed.
In the end a destroyer was selected which might not have been the obvious choice to make. But, the destroyer is a type of warship that is easily recognised by people and it also fitted in with the theme of the publication. Also, the model was not based on a specific vessel but could be modified to represent any of the single funnel types built for the Royal Navy during WW2. This might attract people with personal/family associations with any of these vessels.
The resulting model is about 35 inches (89 cm) long with an operating weight of 5/6 pounds (2 kg). Knowing that some people (through ignorance or bad advice) would overpower their model, the prototype was fitted with an RE540 motor and six cell battery pack. Using a two bladed racing type propeller, the model is much too fast no matter what your definition of "scale speeds" might be, but it was safe. Using a finer pitch three bladed propeller produced a lower but still exciting top speed that most people ought to be happy with (well, assuming they can avoid hitting things).
As I said, it was a challenge, the hardest thing was ensuring that the parts for laser cutting would fit together correctly, but the final result looks the part of a dashing wartime destroyer.
