Mike,
Just a note on wing area. Tower catalog says the figure I used i.e. 456 sq in. Their tech notes on the web site says 600 sq in!

By training and inclination I am an Engineer, my field is electrical. The electrical and mechanical engineers usually rag on each other quite a bit when collaborating on projects.

Usually in my field you can trust the printed data!! Grin - The salesman assured me in would work!

Thanks for posting your progress. I'm getting rather interested in this little bipe!

John
