So sorry to hear. I have built 3 of Bill's Enterprise-Pro kits. They are great flapless, profile models. I first met him at Huntersville and visited with him there on several occasions. At the contest last October, he assisted me when I flew my first ever full PA pattern. He seemed really proud that my first PA patterns were flown with his kitted model. This is a great loss and I send my heartfelt condolences to the family.
