This may have already been posted about somewhere here in the 356 section. I am assuming these were from 356.

This is a YouTube channel about odd aircraft (a very ood channel). This US Navy weapons system that was never built was using a remote controlled, twin, counter-rotation helicopter to launch Mk-48 torpedos. This video right around the 6 minute mark states they were using 72 hp Porsche motors.

Interesting!
