Typically, you want to only add enough reflex to remove the airfoil's natural camber. This is only 1 to 2 percent on most slope foils. There are some foils, such as the RG15, which many feel don't benefit from reflexing at all. So, try a 1/16 of an inch, but examine the results closely before you become a believer. Cambering will typically slow the plane and increase lift. Though it's difficult to know if you've really made much improvement it often will somewhat. Again use a small amount. Again, I'd guess only a 1/16". Bill Swingle [EMAIL PROTECTED] Janesville, CA RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
