Doug you are so right about how you unplug things. I also use a Parsons Products saftey clip to assure the connection stays together. I cringe seeing how some guys yank wings off pulling on the extensions to unplug things. Cycling my flight and ecu batteries right now for the first jet event for the year for me and found that my 2 year old JR 3000 mah battery is deader than Jimmy Hoffa that was in my reaction for RX and servo power.
