I fly my favorite electric, Stinger Pylon racer (140 Mph) its good practice for the eyes ,since it is so small and fast. Also my Jepe F-16 electric, and the Alpha Warbirds from Hobby Lobby are great for formation flying. Believe or not I like to go out and Throw my XP-4 Discus Hand Launch Glider and catch a few thermals and spec it out. Jack.
