Dan I noticed that Scott's fuselage (http://kr-builder.org/ScottCable/index.html) has diagonal braces on the top surface. My old KR2 plans do not show these diagonal members so I assume the original design relies on the turtledeck to close the "box" and provide torsional stiffness for the fuselage.
Are the diagonal braces shown on the later KR2 or KR2S drawings? If they are, can anyone advise if there was any incident that prompted RR to add them? I'm sure they are a good idea but wondering if I need to add them to my KR2. Thanks Phil Maley Perth Australia
