Mmmm… Geoff and me were talking about this idea in another thread, but better move the discussion here, as it looks other people have though a lot more on how to build this…
Some of our thoughs follow:
Rigid wings are allowed in RG65’s, but their whole lateral area is to be counted as sail area. The 12mm diameter rule applies to the mast when it’s not counted as part of the sail area… If I use a 30mm chord wing-mast, and count it’s area towards total sail area, then it’s not illegal… Just read about this!
Not a bad idea at all! May be tricky to get it to move freely around the mast when wind is pressing the sail… worth a second though. Oh, 12mm. dia is the maximum allowed. Typical RG65,s masts are 6mm dia.
Today you can buy a stiff 6mm dia. carbon fiber tube. I’ve never seen a different shape. A non rotating 12mm chord airfoil was what I was thinking of in the first place…
