Hi,
yes, in 1967 I built a 32 inch version, scaled from the original magazine article. It was fitted with a cabin I drew from plans of the Vosper Ferocity and a Bofors gun on the foredeck. I used it regularly for over ten years before giving it to a friend who burnt it - shame.
Hull was 1/16 ply sheets steamed to shape on 1/8 frames. Cabin 1/32 ply for curves with 1/16 for the flat surfaces. A strong and stable boat that took a lot of abuse with no damage. Originally powered by an ED Racer 2.46 diesel, with home made reed radio, then a K&B 35 glow engine with a Sanwa digital radio and finally an OS 40 FSR, a really powerful engine for its time.
I still have my original drawing and think of building a new one for electric power. It was one of my best ever models. Recommended!
