I have a plane that I recently acquired. When the battery for the receiver was removed, the terminal had been melted a little. I did not think much of it at the time, could have been done when putting heat shrink on it. It had a 5 cell Nicd battery. I replaced the battery with a Fromeco 5600 7.4v pack I have the battery run to a M.P.I switch/charge jack, then to the regulator, then to a new receiver. After about 30 seconds the heat sinks on the regulator become very hot. It is the adjustable type regulator. So, my question... is this normal, if not where could my problem be? All the servos are working correctly. Maybe a bad servo motor?

Thanks for any help.
