I have pretty much decided to someday build an electric Klemm. Full scale span is 13 m, length 7 m (varies with engine). At 1/6 scale it's 85.3" long, 13.4" root chord, 51" long, and about 923 sq in area. At 1/5 it's 102.4 span, 16.1 root chord, 61.3 long and about 1330 area. (Rough dimensions all).

Here's a first version Klemm model I found on the internet (think it was a German builder) to whet your appetite.
