Thanks Mark, Since the center spar is already done, nice work too, I was thinking that I would build the new 15% KR-2S wing without the foam spar extensions. This will mean that I will have a little less wing area but I don't see that as a problem.
The goal for this KR will be to build it as light and simple as possible, simple day VFR with just enough fuel for 3 hours, or so, of flying. Although I have been thinking about adding a small aux tank in the right wing stub that can be transferred to the main tank, even 4 gallons would add a little more air time for those intermediate range trips. I've spent a lot of time building freeflight models and R/C gliders so I understand how to build light. One way is to keep all of the glue joints tight and use only the right amount of adhesive. It's amazing how quickly the glues and excessively wide bond lines add weight to the finished product. Same for epoxy and cloth, use just enough to wet the cloth out and not a single drop more, epoxy is heavy! I'll be using a single center stick, nose gear and very simple avionic's. I'll will have to be careful with the ounces that I add in order to save a few pounds in the completed plane. Should I order the 2S plan supplement sheets. The firewall is complete and I'm going to use a 2180 and not a heavier motor so I don't know if there will be any useful info for me in the extra 2S drawings. Thanks ...

Is this true or > did I simply "misremember" something and it's no problem.< True, KR2S and KR2 WAFs are different, in that all rear WAFS are bent, rather than just half of them. But if you're building a KR2S wing, that'll work fine. Those WAFS are almost identical to RR's, just a lot less expensive! They are laser cut rather than stamped. And yes, Troy is using the new wing on his KR2, and is quite happy with it (see http://www.krnet.org/as504x/ ).
