As I mentioned earlier, the final balance required only about 1/3 ounce. Here is a picture the battery compartment. The small jack and LED are for charging the on-board glow driver. The glow battery is aft of the reciver battery. All of this is mounted on the plywood tray you see here. The tray is mounted by clamps to two side rails that run from just behind the wing mount back to the first former. I have a toggle switch installed in the left door and a DuBro switch thingy for the receiver mounted on the right door. I elected to use a toggle switch so I'd never get confused as to which switch was which in case of an emergency. Inside the window you might be able to see the buzzer that is supposed to sound when there is power to the glow plugs. Mounted on top of that is an LED for the same purpose. Unfortunately, the Radio Shack piezo buzzer is not reliable.

That's about it for now. I'll post a picture with cowl in place when I reinstall it.
