Folks
I am getting started on my cockpit module and as I want to install an auto-pilot, I am planning to buy and install the servos whilst everything is easily accessible. My thinking at the moment is to buy Trio servos as these seem to be well supported by the various EFIS manufacturers. I have a couple of questions: firstly, are Trio as good as their web site says they are? And secondly, there is an option on the Trio to have auto trim adjustment – is this worth having and is it approved by the LAA as part of the auto-pilot mod?
Cheers
Rick

I have the Trio (wing leveller) and think its great - easy to fit as an after thought and no weight penalties over the turn coordinator I took out. Links to my Skymap 3c.
The company has made good progress with its equipment in a short time and when I have met the owners at Sun'n'Fun they seem to know the business well. My opinion only.
Can't answer the second part but Ian Rickard possibly can (Mods rep for the Club).

Yes Trio has a good reputation.
Only the roll autopilot mod (SM 10507) was approved by the LAA directly. The Roll Autopilot became Europa Mod 75 and I documented the Altitude hold as Europa Mod 76. Mod 76 does not cover the auto trim feature of the Trio.
Mike Parkin is, I believe, experimenting with the auto trim but I have not heard what progress he has made. Francis Donaldson has some reservations regarding autopilots and electric pitch (see this months LA article). As my aircraft uses the TruTrak servos, I cannot do the work on this directly. If someone is making progress I will be happy to feed this back into the Europa mods.

Hi Rick,
I have both roll and pitch servos connected to my Dynon D10A. Working very strong for an unbeatable price (750$ X2) if you have a Dynon EFIS.
No autotrim, but indication if you need to trim up or down. Really nice!
Just a button on the stick to enable (and disable) both servos to maintain heading and altitude. If you have an AP74 (specific autopilot user interface), you have dedicated controls to set the altitude/heading bugs and needed horizontal mode (heading or track or course following the GPS flight plan). Even without it, using the menu is pretty OK.
The installation is similar to the one with Trutrak servos without the hassle of their D connector that is preventing installation in a monowheel.
Jacques.
