Will a 2012 CTLSi AP autotrim?

So whenever I fly with my AP on I constantly have to trim nose up / down. I try to trim the plane as best as I can before engaging. Is this common? I would have thought the AP would automatically trim for pitch. Is it only for Roll and Yaw? I had thought it was a 3 Axis system. Sorry if I sound arrogant, still new to so much of this and trying to learn!

Thanks everyone

The AP should be 2 axis, pitch and roll. The third axis is yaw, and I have yet to see a CT with yaw control. It should be capable of holding altitude.

Tom, it holds alititude or seems to but its constantly (every maybe 10-15min) asking me to retrim for pitch.

I have the Dynon... The system does alert “trim up” or “trim down” but only in the early stage of the AP selection.  Once in a while, it will alert for a change but only in a goofy wind situation.  I have flown with the  AP in hours-long stretches with no Alerts... after the initial alerted trim.

Your AP should not have to "hunt" for trim if you are flying at a steady speed.  If you change speed or throttle setting you might need additional trim until things stabilize, but once in a stable speed/attitude, you should not need any trim changes.  There may be a sensitivity setting that needs to be tweaked.
