Default RE: Plank design info requested.

Thought I would show you my plank wing for thermal flying. It is an my enlarged and updated version of David Jones's Raven 2M. My Raven 2K is 100" span ( 48" center section with 24" tips). uses a BW050209 airfoil and is wood with 1/2" carbon tube spars. It was a good flyer till it rekitted itself on launch last fall. A new 120" version ( 48" center section with 36" tips) is on the board and will fly next spring.
