getting close to ordering the empennage...
... and I was wondering what the determining factors are for going with electric trim or manual trim. I am thinking I want the electric trim but if that means I can't have something else "really cool" then I want to know that up front so I can make an informed decision. I did a forum search and found a lot of discussion on weight / failure potential / spar hole room / ease of installation / slop, etc. I know everything is a trade off - I just want to make an informed decision and to know that the $325/electric trim is worth it.

Jim, just informing you that $325 in gas will cover half of the CONUS in your RV. The leaner (read "less cool") you go on your built the more country you see. Unless you are building a show plane... then it's a different story.

Completely understand what you are saying Vlad and the $325 is definitely a trade-off. I won't be building a show plane - so for you, you are saying the money is the determining factor in itself? Thanks for the input as well as all the inspirational trips you post about!!

I got the electric trim for one simple, basic reason: I like being able to trim the aircraft without taking a hand off the controls. I did my private in a DA-20 with electric trim on the stick, and got used to that. Now I'm usually flying an Archer with manual trim; it's not any kind of horrid inconvenience, mind you, but I do miss just being able to move my thumb to get the plane trimmed instead of reaching down between the seats.
And really, in the grand scheme of the entire build, $325 is pretty small potatoes. At the end of the day, only you can decide what plane you want and what it's worth.

Thanks Philip - Currently I fly a 172 and the trim wheel is on the column below the panel - so I don't think the manual would bother me - I was just thinking of going for the electric for ease of installation. I guess I just wanted confirmation that if I went with electric trim, I wouldn't be excluding myself from some other option that I don't yet know about. In general, I want to build a light-ish plane, 180hp, cs prop, medium glass panel (meaning not a full blown glass panel), because I hear the lighter the better.

Electric trim is great
I have electric trim on my RV-8 with trim buttons on the top of the stick. I love it because I like to keep the plane in trim all the time. Without moving my hand from the stick, I can constantly trim off any control pressures. That way, I am always controlling the stick with thumb and index finger and it is always in trim.
I fly a couple of other types of planes without electric trim and find myself frequently pushing on the top of the stick in an effort to change elevator trim.
Finally, I know of nothing that you would give up by installing electric trim. I think that it is well worth the cost.
Good luck with your project. The RV-8 is a wonderful plane; you are going to love it!

Thanks For the input Dan! It's all about what you get used to, huh?  Glad it is not an either/or scenario with the trim - and I am really looking forward to starting this journey!!

Is there anyone out there that has the manual trim in their RV-8? If so, how and where are the trim wheels configured, lacation in the cockpit, etc? If there are threads out there on this, please post. Thanks! ~J~

John,
The elevator control is a vernier type control that is located on the lower left side of the panel (I believe). The aileron trim is a little slide lever that is located on the left cockpit sidewall.
