HI DOC, It doesn't sound like you would have much of a problem building any ones kit, with your experience. P.K. Guillows is in my home town so I am familiar with stick and tissue models. I feel with the manual dexterity required to build one, plus your scratch building experience, you shouldn't have any problem. The biggest difference is the money, and the amount of time that needs to be dedicated to complete a large bipe. I have built several BUSA kit and bought a lot of balsa from them over the years. When I have called them on the phone, to order, fix a problem on an order or a question about building a kit, a cheerful lady answers the phone, an she quickly fixed any problem with an order, with any questions about building a kit, the call was transferred to the "shop", and the guy that answered my question sounded like he designed the kits. When I'm done with my call, I always feel they were glad I called, not just some one inconveniencing their day! Great kits, plans, instruction manuals, and support second to none. Jim
