Here are the interior shots Tom Riddle Requested. I had mentioned to him in another e-mail exchange that I chose not to use the mounting plate because I like to inspect servos before each day of flying, and removing/re-installing the plate was an extra field assembly step I didn't want to perform each day. So here's my solution, which allows me to do a quick check of everything inside before flying.

It's tough to capture in pictures, once it's assembled. I attached the Rx to a Ply plate installed vertically, just behind the fuel tank. Pics 1 and 2 show the plate (I pulled the tank a little forward so that the plate is easier to see. The receiver is mounted on the opposite side of the plate (only the zip ties are visible in this picture), so that it is underneath the throttle servo. The vertical ply plate is mounted to the servo tray with 2 4-40 bolts and blind nuts. I also use a rubber band to keep the aileron extensions near the top of the plate, so it's easy to hook up the lower-wing ailerons when I assemble the plane. I mounted the batteries to the side of the rudder servo. I have 2 1600 mah NiMH batteries, with one mounted below the servo tray, and the other below the servo tray, with 1/4" foam on each side of the servo tray to absorb vibration. This setup allows CG to be set exactly as specified in the manual, and the plane slowed down nicely for landing, with no nose-heavy feel (I've only had one flight on it so far). I haven't quite decided what I want to do if/when I want to move the CG back. I'm more into aerobatics flight than 3-D, so I may leave the CG where it is.... time will tell. The third pic is a better one, zoomed out so that you can see the entire installation. You can also see the ignition battery (1600 mah NiMH) mounted just behind the forward bulkhead.

Hopefully this is useful to others who are in the process of assembling their bipes.
