Subject: | TruTrak Autopilot |
Hi colleagues,
I posted it on the TruTrak forum a week ago without any feedback.
So I give it a try here assuming that here is considerable experience with
TruTrak autopilot's available.
So I have a Digiflight II VS since a couple of years but tried it first on
my first flight two Weeks ago.
Engaging it during flight resulted in immediately descent - and yes the
descent rate was 0 on the display.
I tried it again on the ground and recognised that even on ground, not
moving the AP tried to move up or down (I do not remember presently).
Up to now I do not know what I made wrong but am sure that one of you
discovered something similar or has a good advise.
Thanks in advance

Peter,
The FAQs on the TruTrak website offer the following:
When engaged, my autopilot dives or climbs randomly
This is most likely caused by a pitch servo that is running in the wrong
direction. Check this on the ground by engaging the autopilot in alt hold
mode, then move the tail of the aircraft up and down. The elevator should
move to counteract your movements; i.e. if you push down on the tail, the
elevator should move down as well. If you have an AP with the vertical speed
select feature, you can simply command a climb or descent. The stick should
move accordingly. If it is opposite, refer to the installation manual for
your AP for pitch servo reversal directions.
Bill
