Hi Gord, I've read your post and I don't have a clue what you are talking about. What were the counter weights floating in? Were they just slinging round and round? Do they have any relavance to modern day giant R/C engines? Please enlighten us.

It has always amazed me at the engineering and manufacturing that brought the massive aircraft industry into full production in such a short time to produce aircraft to support the WWII effort. We must never forget the highly intellegent people who did this.
