Hi Lyle, The original box with most parts is out in my garage! I'll go out there tomorrow to take a peek to see if any plans were enclosed! Don sent the kit to me many years ago, 1991 or '92, and I never did get up enough enthusiasm to get after it! I do know that Don cut his own cores can't say if they were cored out or not though. I did fly his original up on the mountain in Reading, PA and it pulled like a horse! I am not a very big guy and can't remember if the ship had adjustable lead outs installed. Will check and see.
