Regulator voltage

[JOddino]

Yes.  If you are running the typical 5 or 6 digital servos and have got your
system setup properly, just plug it in and you are in business.  If you have
a setup that draws high current, like an IMAC plane or some helicopters with
high performance gyros and TR servos you might need a heat sink.  I like to
see two regulators in parallel for those applications but one is fine for
pattern planes.
