Does anybody have an install manual to sell or share for the S-Tec Remote Gyro P/N 6444 and Fluxgate P/N 6446? Essco doesn’t have it and I can’t get an answer from S-Tec. Thanks, Don

S-Tec sold that compass system to PSI http://www.pacificsouthwestinstruments.com/
From an avionics guy point of view, It is a horrible system and requires overhauls more frequently than say a kcs55 or NSD system. You might consider the solid state SG102 replacement for the KG102 that has just come from Sandel.
If you have this unit and it hasnt run in a few years or been overhauled recently what you will find is that the gyro will hunt around alot back and forth upon startup not able to find a stablized heading becuase the grease on the gymbals in the remote gyro has turned to sludge. The operating of the bearings in the unit actually makes heat that will "melt" the sludge and allow the unit to make it into a normal operating mode.... but obviously this is no good. S-Tec started using a different grease in the gyro right before they sold the line to PSI. The gyro should be ready to go from a cold start within 30 seconds really and if it is hunting wildly and takes longer than that, your remote gyro really needs a repair or overhaul.
If you still need the drawings I can see what I can dig up at work.

After receiving Charlie’s email, I looked into the Sandel SG102 and I agree that any AHRS system would probably be better than a conventional, motor-driven gyro. Any thoughts out there on what AHRS are currently available for certified aircraft and which unit would provide the best bang for the buck?
