The Rapi-Dos is our highest performance speed wing designed for pilots who seek the ultimate in speed and swoop performance. It has the widest glide performance range of any wing we have ever flown, and handles incredibly steep angles as well as it does flatter-trimmed flight for transporting to different sections of your line, or accessing a distant LZ.
