These airfoil templates were drawn up at a time when many of us had spars built and in place, but were questioning the RAF48 when better airfoils existed. We were fortunate to have an airfoil expert design an airfoil especially for the KR2S for us. And a "selling point", from the safety point of view (and to short-circuit the naysayers), was to use the existing spars. It may not have been the perfect solution, but lengthening the horizontal stab and using a more effective airfoil for the tail surfaces improved even more on the longer KR2S. If you'd like to draw up another set of templates, along with a new spar design to match it, I'll happily add them to the "new airfoil" site as a fourth alternative for "new construction". In the meantime, those of us who've built wings per the original templates and put hundreds of hours on them will probably stick with what we have...
