Yeah..you have to take away the airframe drag, and also remember that as soon as the plane moves forward, the static thrust will go down, as it is no longer static.
Was the 9lb figure from measurement ot Thrust HP?? If Thrust HP...then about 6 1/2lbs would be my guess. Sounds about what you were getting.
