Hello Everyone,

I have searched far and wide for the Cri Cri MC15 airfoil coordinates without success. Can anyone tell me where to find them or provide them for me?

According to the Incomplete Guide to Airfoil Usage , the MC10 uses a "Wortmann 21.7% mod". Doesn't seem to mention the MC15.

Hello Greg,
There once was a Yahoo Group dedicated to the Cri Cri drawings. You might try there, although I seem to remember some animosity from another group. I do have a complete set of original Cri Cri drawings that I can sell. I just need to figure out how to do that legally with M. Coloban.

Hi Greg

From the CRICRI MC 15 plans. The second image shows nose radius.

Isn't there a foil shape for that fancy flap?

Looks like there's. CAD model of the MC15 on Grab CAD. NO IDEA IF IT'S

A wing with an approx 20" chord and approx 4" thick. I know the Cri-Cri is tiny, but I hadn't seen the actual dimensions before.
I also didn't realize the wing was so thick ( 21.7%).
Thanks much.

I think the thick wing may work well with the flaps (flaperons?) too.

Hmmm.

Chord is about 18.9 inches. Wing thickness roughly 4.125 inches.

Flap adds maybe 5.75 inches - in projected chord at 0 degrees.
