| F.J.H. *341 How has this come about? from Mx{John H Maddocks - Chief Proving Officer} Mx{John H Maddocks - Chief Proving Officer}17/T2/7.36 PHANTOM III SERVO The servo damping scheme as fitted to Phantom III gives considerably more damping than is necessary. The damping loading spring is much too highly rated, and in every case we are having to set this so that there is no load on the spring at all.
