Installed a new to me Trio EZ Altitude hold on my RV9 along with the gold standard servo for pitch. My intent is to gain altitude hold to supplement my Trio EZ pilot roll and GPS track wing leveler control which had been in service and worked well since 2008.
The Trio Altitude Hold control device can be installed "blind" and I chose to install ( with correct orientation ) on to the forward side of the panel that's forward of the instrument panel. (that places it about 12 inches forward of the instrument panel) It has both velocity and and static ports to connect to use all the features of this EZ model.
It works as it should BUT it drops out VERY often I believe due to " excessive Gs". That is a electronic feature in the head that provides some protection. My issue is that mild bumps in normal flying will knock the altitude hold off. In perfectly calm air it will remain in and works fine. Most days its off every 5 minutes.
My question is : is it possible that where Ive got the control head mounted is not acceptable due to being to forward of CG. And it's like riding in the back seat of a long school Bus! The G forces are \amplified and it take the hold out on excessive Gs
I see some who have chosen to mount the head to the rear of the baggage bulkhead where the pitch servo is mounted. A location where the ride may be a bit better . Maybe I need to relocate mine??
Interested in hearing comments of users of Trio EZ Altitude hold units , where you mounted the head unit and what experience you have had with that stand alone device. Thanks for any comments you may have.
