Hsi issue

[Joe Larussa]

I have a King HSI with a Stec 60 autopilot.

The Hsi is oscillating back and forth three degrees. I have overhauled the Hsi and the remote gyro. The slave switch is a little funky. Could that possibly be the problem?

Just curious how much the overhauls cost. Ours is out right now for the same.

To overhaul the gyro is 1200.00 bones

Good to know, I thought it would run a whole lot more than that (assuming no major problems found).

I have not seen this so I don't know for sure but it sure makes sense that the slave function could do that if it had an intermittent connection. But you would need to talk to an avionics guy. There is also an indicator by the Slave switch with an adjustment knob - if the indicator is also moving around with the HSI that would sure seem to cinch it as the problem but absence of it wouldn't rule out it either.

I can finally put this to bed. Turns out that there was loose pin connection in the remote gyro that was grounding out. Was difficult to find but its now fixed!
