Did I read that correctly? The aircraft stalls at a SLOWER airspeed with stall strips? I thought stall strips were there to induce a stall in that portion of the wing. When used near the root of the wing they force the stall while you still have aileron effectiveness -- like "washout", decreases the likelyhood of a wing dropping -- and cause turbulent airflow to strike the tail producing a buffet to warn of an incipient stall. How could inducing a stall earlier (faster) at the root of the wing do anything but RAISE the stall speed? Are these stall strips or vortex generators? ------------------- Paul Davis Lancair Legacy builder pdavis@bmc.com Phone 713-918-1550 ------------------- Fallaces sunt rerum species The appearances of things are deceptive
