Hi all. 8178 suggested I might start a thread on a Kaos I'm building from that old set of CAD plans drawn by Gerry Yarrish that are floating around on the web.

First, I need to say that I have scaled the drawing to a 42" span to suit an available engine (I actually don't own a single .60 anymore). So if this is Classic Pattern sacrilege I'm sorry. In that case, this thread may not even belong in this forum. Anyway, I want a Kaos, and until I can afford to splurge on a new engine I have to build for what I have lying around.

Since I don't have an original set of Bridi/RCM plans I don't know how much these CAD plans differ from the original. I can say that they are the definition of simplicity. All of the wood dimensions scaled perfectly to common sizes except for the spars which came out a bit funny at 3/8 x 3/16 for the mains and 3/16 x /3/32 for the rear ones.

Here is a pic of the plan as it comes and one of the parts - and there aren't very many.
