The Xstream glider is the world’s first application of IWA (Internal Wing Aircraft) technology. Each purchase helps to fund on-going research and development of a real man-carrying IWA. This glider soars through air and water in a unique way:  when it’s launched, air (or water) is directed along the fuselage, over the coanda and is entrained into the duct. The internal wing, or the bottom of the duct, accelerates the flow, creating enhanced lift. A power launcher is included for extra distance.
