Davo -
I used to have one but I sold it years ago and don't remember.

If nobody comes up with an answer you can put up a dimensioned sketch of the wing and I'll magically calculate the cg position using a piece of paper, pencil, and beer.

Which Ruby? Airtronics or the molded one from Soaring USA?

Howdy,
the Article I took this infor from seemed a bit short, I'll believe the 95mm, seems alot more resonable to me!
Thanks Paul!
