How useful is auto-trim?

Are there major pitch changes with flap deployment?



The reason for the questions is that I have MGL Odyssey EFIS panels and 

their servos .... and they just came out with their SP-10 auto-trim module.

After flying for while I "automatically trim" when the flaps come down. I don't even think about it, at this point.

For a long flight, auto trim is really nice. Not required, but really nice.

I believe Garmin's new servos wire into the existing trim motors and will 

auto-trim when autopilot is on.

I have the Trio Pro with autotrim, and it's a 'nice to have'.  It lets the autopilot fly the climb, level out, speed up, and it does the trimming. Same on an approach, with slowing down and flap deployment.

Also I use it manually, when hand flying, to make fine adjustments, since the trim speed is airspeed sensitive.

Auto-trim is *awesome*.  I have it on the RV-8 with the TruTrak AP and it works fantastic.  On the RV-6 with the Dynon, I do NOT have it and miss it like crazy.  The Dynon is always crying about "Trim up", "Trim down".  Waa waa waa.  Get's annoying.  



Invest in the auto-trim.  You won't regret it.

Yes, Garmin's new servos have auto-trim built in. Easy, clean install.

I think auto trim is great.  I installed it after about a hundred hours and found it greatly reduced workload, especially during instrument approaches.  It's one less thing to think about, especially since I never really found the TT trim annunciator to be all that intuitive.  That cascading bar-graph thingy tricks me about half the time...

Dynon just announced today their new auto-trim module, along with a 

whole slew of new features! No more "nagging nanny" about trim anyway.



Unfortunately, this means a lot of rewiring to retrofit. ugh.

But the auto trim is just one of many features of their new auto pilot control panel, so that feature is virtually free and not required.
