Your initial post to this KR educated list left many people shaking their heads due to some obvious lack of research on this aircraft. It was painfully obvious your enthusiasim overloaded the brain.
First of all, you said you would buy "kits" from RR. There are no such things. This is a plans built aircraft whose plans, including errors, are unchanged for 30 years other than the addition of the S model. Royalities would not be an issue, liability for an aircraft built by you would be. If you are going to use premolded parts, manufactured part, final builder fabrication or simply install are all going to affect the required documents YOU must file with the FAA to verify authoritatively your compliance with the 49% rule. This documentation is much more detailed than the builders logs required by a FAA designee upon final inspection. If you, as you say, are planning on installing GPS, long range fuel tanks, transponder and ox. systems you will be into systems and way past the 49% rule for kit manufacturers and building an airplane. This is just the head of the bubble. Your question concerning an alternate wing material could have been researched by a check of the archives or a search on the internet for "fiberglass wing alternative". One of the most obvious to any builder would be to fabricate molds and vac. bag your own skins. You will find some people have used wood as an outer surface. Your questions concerning ox and instrumentation, while nice, are pie in the sky issues with the KR. Portable ox. system? Just put a bracket somewhere, like a fire ext. holder, and snap in the bottle. Better not be aft of the rear spar though. Nice questions, but simply answers if you study the airplane a little bit. Once again, I'm not flaming you but a small amount of research would have revealed too you the labor intensive nature of this airplane. Most people approach this airplane because of it's relatively inexpensive final price. This price can be varied enormously by individual builders. This airplane can be built by someone with practical common sense using tools most builders have in their shops. You will find most KR builders will not buy something they can easily construct in their garage. There are very, very, very few parts in this aircraft that cannot be fabricated in this manner. While you may get lucky and pull this off, it just appeared you put the cart before the horse and did not do your homework before speaking up in class. I am not saying it can't be done but you better come up with a business plan that will take you from A to Z. Like many people have said, "If you have money to burn, get into aviation".
