Traplet publish a plan but I think it's a much simplified version. I gather that Scoonie Hobbies do – or did – a moulded hull and superstructure. Again, the word "moulded" doesn't imply much in the way of scale fidelity. As for the Premier offering, two grand for a static model of it wouldn't be the most popular purchase of the year in this household!
Ah, me – back to bash a bit more balsa.
