All of our models??, Sorry my name is Robert Godfrey, Son of the late Bob Godfrey and President of Precision Aviation Design. I had worked with my father from the early 80's untill he passed a couple of years ago. I have been designing models from about '95. I did the 10% verification from the late 80's on for all of our models including the present designs. Also I see that I mispelled our websites address its,
www.bobflies.com there is a write up on dad on the main page that has some of the history you are talking about. We still produce models here in Florida and I take care or my Mother here also. All of the present production models will fly Pattern or 3D without any C.G. change by design.
Thanks,
Robert
