This model is illustrated on the last pages of the 1999 set 10 manual, but the low quality of the photograph means the details are hidden. I have built it from the contents of the set and it seems to work well.
It is a futuristic propeller-driven car, with a rear wheel driven propeller which turns when the model is pushed along.
I feel these extra models in the manuals from the Calais factory, of which there are many, are very challenging to get right.
