Slender, flexible wings are vulnerable to flutter at excessive airspeeds, and a glider designer has to know when flutter will set in. The "never exceed" speed of an airplane is usually determined by steady-state loads on the airframe, but for fiberglass gliders, flutter is usually the limiting factor. -------------------- Ralph Jones LS-4a N49LS 6R Post Extras:       Pages: 1
