Adaptor body and square drive bendix shaft to accept a Wunderlich-style flex shaft.
Works on VX-1 and VX-2 rotor heads.
Building the GT-VX1 was a great experience, everything fits as it should. Whenever I land somewhere, everybody comes to look, and the attention to detail gives this gyro a beautiful professional look. Flying my Gyro Technic is even better! It is very maneuverable and smooth. My confidence level is extremely high when flying this Gyro. - Brent Bruns N628Y (St. Joseph MN)
