I am just getting started on a 7 empennage and would like to know if I
need to be aware of any special planning if I will be installing an
autopilot? I have no idea of how and where the autopilot servos are
installed? Any help from the more experienced would be much
appreciated.

Ken,
There is nothing special you need to do on the empennage to prepare for an
autopilot. Some point during wing construction is a good time to start that
process and at least lay the groundwork. It is easier to install your roll
servo in the wing before the wing is closed, but even if you defer that
choice, you can retrofit a servo into the wing or fuse later, but with a
higher degree of difficulty.

KC -
I think you'll find the TruTrak pitch servo installation typical of all the
autopilots that you'll be considering. Here's a link that showing that
installation:
http://www.trutrakflightsystems.com/documents/RV-679PitchInstall.pdf It's
just aft of the F-706 (baggage) bulkhead. You won't get to that until
you're working on the fuselage kit.
Build on!

Not the autopilot, but the trim, concerns the empennage. Electric or manual
elevator trim is different there.

KC: IN THE RV-7 THE AUTOPILOT ELEVATOR SERVO MOUNTS BEHIND THE ELEVATOR BELLCRANK ASSEMBLY BACK BEHIND THE BAGGAGE COMPARTMENT AND CONNECTS TO THE BELLCRANK VIA A SHORT PUSH/PULL ROD. IT LITERALLY MOVES THE ELEVATOR PUSH ROD BACK AND FORTH - THEREBY MOVING THE ELEVATOR UP/DOWN. THERE IS NOTHING YOU NEED TO BE CONCERNED ABOUT OR MAKE PROVISIONS FOR WHILE ASSEMBLING THE TAIL COMPONENENTS. YOU'VE PROBABLY BEEN THINKING ABOUT THE ELEVATOR TRIM TAB AND MAYBE THE TRIM TAB IS MOVED BY THE AUTO PILOT. THAT IS NOT THE CASE.

Ken,
I installed TruTrak servo brackets in my RV-7A while building.
There's nothing to worry about with the empennage. One servo goes in
the wings and the other one in the fuselage, as others have pointed
out. So there's nothing to worry about until you're about finished
with your wings. One aileron bellcrank bracket is replaced with the
one designed to hold the servo in the wing. You can see how I did it here:
http://www.europa.com/~swayze/RV-7A/Wings/20080908.html
And here's how I installed the bracket for the pitch servo in the fuselage:
http://www.europa.com/~swayze/RV-7A/Fuselage/20090620.html
Good luck with your project.
