I had a Goldberg Wild Stick 40 a few years back. I flew it so much I think I wore it out. Anyway, it had flaps. I would have fun with it by climbing high (as we say, three mistakes high - ) and deploying the flaps and pulling full up elevator at the same time. The plane would do a loop in just about it's own length. Fun to watch. I never used them while landing.. that plane never needed them. It would float in and land with almost no airspeed.. ok..ok.. it had some airspeed..
