Mike's answer here is the first to really hint at the solution for speed. Horsepower is great for climb, but if you want to go fast, work on drag reduction. If you want to go even faster, work on weight reduction. When I first finished my KR, I was pretty disappointed in the performance. I c

I can give you an opinion from a guy who has been looking for the best of the best options and what I am seeing with N886MJ. First, Larry is right. In my opinion this design has been pushed to its limit. At this point most everything has been tried and the best options are being used. If you

Ken; Just cut a piece off and compare the outside color to the middle of the same piece, the sun would not have gotten to the inside of the foam. I would NOT be afraid of using the foam because again it is NOT intended to be structural only to hold the shape as a mold for the fiberglass. Parl
