I have 2000 plus hours on my RV8 with the electric trim on aeleron and
elevater. I installed a 4 position top hat switch on the top of the
control stick for easy operation. The only mod was to install a speed
reducer on the elevator trim motor. It was an easy install. The speed
reducer is necessaary on the elevator inorder to fine tune elevator
cruise position. The aeleron trim allows me to use all of the fuel from
each tank at one time on long trips . It is nice to know exactly when a
tank is out on a long trip. I did not use tabs for the trim. I cut
sections from the trailing edge and made new pieces that are hinged as a
part of the aeleron /eleator. Nothing sticks out.
It takes time to do this, but i found it well worth the effort.

Subject: elevator trim, manual vs electric
I am doing final assembly on a 6A. I've never had the trim cable fully
installed before and am running into various problems that have me
reconsidering things.
The manual trim has the advantage that it is not electric - no wiring,
no dependence on the electrical system. I also like the very positive
connection from my hand to the trim tab. But, (I'm guessing here) the
electric looks like it's a lot easier to install. It's probably also a
lot lighter. Though, I've heard lots of stories about the servo's
running away.
Have any of you converted from manual trim to electric? Is the
electric easier to install/live with?
