To all that have requested the foamie airfoils. I'm not releasing the coordinates for 12 months in deference to Pat Bowman, as I designed the airfoil specifically for his toy. Sorry about that. Ask me next October if you are still interested. Joe PS Flew my very own JW for the first time last Friday in good Santa Anas at Parker. My guess for the wind was at least 35 mph. It will flutter, but at somewhere around 150 mph or so. It is just TE flutter, not whole wing flutter, so it is easily solvable with stiffer control surfaces. Played with mass balancing, which worked for as long as the brass tubes stayed attached. I'm gonna make a better mounting system this week for really strong conditions. Amazing toy, especially for a foamie. RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
