My RV-6A was built in 2008 and purchased from the builder.
It has electric pitch and roll trim. I consider the electric pitch trim essential because of the poor ergonimics of the manual pitch trim. i would be happy with the spring biased roll trim.
It has an altitude hold pitch servo. I only engage it when it's rimmed in level flight, so no need for auto trim.
It also has a coupled roll trim that is very handy. I'm quite happy with this relatively older technology.
