On the throttle servo mount I recomend that you reinforce the bottom with either triangle stock or 1/4" spruce sticks. If you install the batteries on the servo mount a hard landing can break the mount. I also use hard wood sticks to reinforce the front of the fire box at the firewall. Here are a couple of pictures. I have also included a picture of how I lighten up the control surfaces. I use a hole saw to cut the holes. If you do this be sure that you dril a hole into the lightning hole through the hinge line if you don't have a hinge going into the hole. The problem comes when you cover the plane. If you don't have a place for the hot air to get out when you shrink the covering you will end up with wrinkles that you can't get rid of.
