Bucky’s motors are very long, in some cases, and require a prop shaft stop. The advantage is an exceptionally long motor run (in some cases over 2 minutes).

The “Code” denotes a family of models that use the same motor. For instance, the Cleveland Gull and the Korda Open Road ( G**) use the same motor.

No attempt is made to indicate torque when fully wound due to batch capability and individual winding techniques. Thermals,  Gene Wallock
