ORIGINAL: Whirligig The problem has been resolved! The Airtronics 94091 servos installed by the previous owner were replaced with Hitec HS65HB and the swashplate is now in perfect phase. The replacement took serveral hours because of the Y-arrangement of the servos but it was well worth it. Evidently the Airtronics servos are better off on a park flyer. The Hitec are more precise. Just a dash of subtrim was needed for the pitch but the others were perfectly zeroed. I can now fly the Poseidon head-in confidently. Whirligig
