All After watching Burt Rutan catch the X-prize I got the building bug once again. Mounted my horizontal stabilizer today and moving on to the vertical fin and rudder. I have a couple of questions on the spar size differences and the bevel on the aft vertical fin spar. According to the plans for the -2S, the aft vertical spar, aft edge measurement is 1 1/2 inch across and the fwd of the edge rudder spar is 1 3/4 inch across. Am I measuring something wrong? Why would the measurement be a 1/4 inch difference? I would think the measurement would get smaller as you move aft.
I forgot to mention is that my KR is not the standard KR-2S. It is 10 inches longer, 4 inches wider, and straight sides. This will change the measurements from the standard KR-2S. My aft spar of the aft vertical fin is 1/8 inch wider at the beveled edge at the base where the fuselage sides will be epoxied onto the spar. Could I make the airfoil template to meet the spar width? Finally, does the bevel, that is required on the aft spar on the vertical fin so the fuselage plywood will glue flat, go or continue all the way up the spar? I think I know the answer but I want to make sure I don't mess something up. Thanks John Esch KR-2SSW Independence, OR (7S5)
