Tony and all, I appreciate a good thread drift! You never know what you'll learn. That is a neat tidbit about the speedboats making some chop to free the flying boats, and I feel for the guy with t ...

The two speed fans on the Rainbow were driven off the propeller hub, but I've never found any photographs of diagrams of the mechanism. I believe the fans were made of a plastic material. There are fl ...
