I am nearing completion of the cockpit module and am considering adding a
Nav-Aid autopilot. Has anyone installed one? Will the servo fit on the seat
back above the pitch cross tube without interfering or getting bashed when
the spars are inserted?
Any details on installation would be most welcome, particularly how it is
connected to the aileron control system.
On an allied subject, Bob Berube advised me that the self aligning bearings
(EUR009) for the pitch cross tube are greaseless. I used the dry graphite
available at auto stores to good effect before installation. However, I found
that the bolts used to mount CS09 to the seat back were so close to the bend
that they caused the bracket to introduce an end load when the bolts were
tightened despite the fact that the seat back was quite flat in this area.
This end load caused noticible friction in the pitch axis. Bedding the CS09's
in flox cured this and reduced the pitch friction (seat module only) to
negligible.
Thanks in advance for any AP advice.
