So first I mounted the motor in it's cage and got it mounted in the proper place on the firewall, (so I can see what firewall space is left for the battery drawer).
This motor looks pretty big/heavy, am I a candidate for the tail mounted servo?
(what does your power plant weigh with prop)?
Here are some pics
I would mount the rudder servo in the servo bay under the wing to start with and see how it balances when it is ready to fly. If you need more weight in the tail it is very easy to move it back. To install it in the tail, you need to cut the covering where the servo mounts. If you mount it in the tail first and find out latter you need to move it back forward, you will have a hole to patch where the servo was.
I don't know anything about the motor you are using, but it sounds like a lot of prop for your set up. I have a 12 cell set up on mine and I'm running a 20 X 10 APC 2 blade electric prop on mine. Mine has been clocked at 114mph and has been logged to 2800' strait up. Mine weighs 16lbs ready to fly. 3200W
