One of the best flying airplanes I've ever had was the top flite Tauri designed by Ed Kazmirski. Kited by top flite in 1964. A club member let me fly his one time . I was new to the hobby then with little experience and couldn't believe how smooth it flew. I get the plans and built myself one. Scaled it up a little . It's considered a trainer but is very capable of doing a lot of maneuvers.
