Sometimes it's hard to tell when Keith is pulling your leg.  This is one time.

The fix is to remove the device each night from your plane and seal it inside an airtight container filled with either dry rice or desiccant beads to remove the humidity from the DIP package that protects the silicon components.  You only need to do this October thru March . . . something about the combination of temperatures at your latitude and humidity.

The output voltages were different, which I attributed to tolerances in two regulators within the device.  If there really is only one regulator in the switch/regulator, I cannot understand why there's a difference in output voltages.

>> Ron - It is a dual regulator/switch which allows you to hook up two lipo batteries and have them separately regulated to 5.9 volts and use one or both of the outputs.  Look here:

I'm looking for a fixed gear 2m design, and plan to do an electric setup. I can convert a methanol burner if necessary.  I live in Nashville,tn., avoiding shipping would be good.
