Hey Hobbiest,
You took the thoughts right out of my head. I have begun to work with carbon fiber on a limited basis and I agree that at least for the basic frame structure it would be unbelievablely stiff if done correctly. I make a carbon fiber/balsa gunstock that weighs in at a heafty 20 oz that you can't twist or bend with your hands.
If you decide to do one le me know as I have some contacts that might be of interest to you.
Mike
