, it may be worth looking at information around model
s by the late Ray Malmstrom. He was an ace when it came to designing unorthodox model
s and another source would be the Plans Handboook. I remember this in the mid 1960s and there was plenty to choose from as they had a special section on such. This included anything from hydroplanes, prop driven racing cars and hydrofoils etc.
Another source could be the Eagle Annual from around the same period. Though the Eagle was a comic, the Annual did have articles around the latest technology of the day. Even if you could not obtain the Annual itself I am sure there would be archives on the internet.
Hope you have success with your venture, it sounds exciting.
