Adaptor body and square drive bendix shaft to accept a Wunderlich-style flex shaft.
Works on VX-1 and VX-2 rotor heads.
I am working on the assembly now, and, as predicted, the parts fit on the 1st try every time. A VERY enjoyable experience so far. No corner has been cut, and the attention to detail is 2nd to none! Thank You! I cannot wait to fly my Gyro Technic! - Jon Louis (Mankato, MN)
