[NSRCA-discussion] Looking for a pattern plane

Wed May 9 09:45:20 AKDT 2012

Ron,
Did you use the same input plug for both lipos? If so, all I can say is 
that it only costs $14. If not, there may be some frontend circuitry in 
there that somehow establishes a secondary and a primary battery input 
to the single regulator.
