[NSRCA-discussion] Looking for a pattern plane

Wed May 9 11:01:17 AKDT 2012

No, I didn't use the same input plug.  Assuming that there were two regulators, I was actually trying to find out which regulator put out the lower voltage so i could put my smaller lipo battery on it and it would be the "backup" battery.  I used the same lipo for the tests, but used different input plugs.  The voltage difference was 0.06 volts.

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.

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.
