KR> New airfoil on old style spars question
I installed my aileron bellcranks per plans with a little change in the pulleys to fix the angle difference with the wing incidence. You can see my installation at mykitlog.com/vr6chris Chris Pryce
KR> New airfoil on old style spars question
This topic brings me to a question I hadnt thought of. I have a kr2 plans built boat stage with outer spars made and all the wafs attached. Does the new style airfoil match the spars positions? What changes would be needed to the shape of the spars of any (shaved down, chamfered etc) ? Also as it appears (iirc) , my boat has the rigging out to the bellcranks on the rear center spar ends so it looks from these messages that those will be too "thick" and have to be redone. I have not yet purchased skins yet. Basically, what can I expect to do moving forward to accomodate what I have with the new airfoil? And if I choose to make the wings the "old way" what kind of labor hours and cost is usually expended and would that make it easir to build the new airfoil onto the original spar position and dimensions? Sorry for long winded question but I think you can see what Im trying to determine here...

Has anyone tried that with no success? Larry Flesner

Go check the airfoil templates at http://www.krnet.org/as504x/templates.html and compare the spar thicknesses shown in the templates to your existing spars. Adding material is easy, and there is likely some room for some removal but I'm not about to sign up for figuring out how much. The goal was to fit perfectly on the KR2S. I will confess to not having checked the KR2, which has different sweep than the KR2S. Mark Langford ML at N56ML.com http://www.n56ml.com
