report next column fairuess should say other manufacturers Toledo excellent exciting products make helicopter flying enjoyable since wasnt didnt get information about will however report helicopter improvements hear about future columns Professor Chris Atkeson Georgia Tech working Flying Swashplate Professor Atkeson interested developing Unmanned Aerial Vehicle UAV can flown computer Although have experimented several designs now interested getting three-rotor-system four-rotor-system vehicle air built structure wood because wood relatively inexpensive easy work Three Schluter Champion helicopters used point triangle collective pitch used both collective cyclic functions proved rather easy using CCPM mixing function Futaba radio flight stability continues problem must solved order achieve precision controlled maneuvering flight Champions point center triangle makes easy control yaw using aileron function helicopter until better defined Champions continues have tail rotor added
