NetHeads, Bernie Wunder heeded the call, and sent me a list of Spruce for the KR2 that he got from Wicks. You might need to check against differences in the S if you're going to build an S, but the only place I can think would be different would be the length of the vertical stabilizer and rudder (maybe), although there may be others. Anyway, it's at http://www.krnet.org/kr2woodkit.jpg .
