Check your pitch servo installation blueprint again under Note 5.The bridal cable tension should be 15 +/- 2 lbs. If it is set to 10, it will certainly hunt in altitude hold.Servo bridal tension is extremely critical in all S-Tec systems because the servos move very slowly, so any slack in the bridal will cause hunting.Also, the altitude transducer static line must be connected into the aircraft static system, not open to cockpit air. The System 50 is like the 30 in that it cannot operate in altitude hold mode only because as soon as you engage the system,it automatically goes into STB (wing leveler) mode.
