I saw sea gull thermaling during the calm days and soaring during the gusty days. Sometimes they also thermal up near the cloud during the 30 mph gusty days. Not sure how they fly under that kind of extreme weather. Anybody know what kind of "airfoil" (root & tip), span, chord, and weight for these soaring experts. Just for a reference, here is a link to Birdworks' R/C Gull and their spec http://www.harborside.com/~birdworks/bwgull.htm Span - 41" Foil - E168 Loading - 10-14 oz/sq. ft Weight - 15 - 21 oz Area - 217 sq. in Looks like a hot sloper. Not sure how they thermal. H.S. RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
