Some years ago I was with my grand son in Wal-Mart and he got me to buy an Air-Hogs delta wing. We couldn't get it to fly at all. It was completely uncontrollable. I took if apart and saved the hard ware. I have an old kit 30" span Wright Flyer glider. The kit is bamboo and tissue. I have thought about building the kit and installing the motors and receiver. The props are counter rotating and very the power to the sides for directional control and up and down. It might work.
