Here's a tip for those of you flying several AA's and using only one transmitter for charging.
Put only the top three batteries in the transmitters used for flying. All six are used only when charging the plane.
If you put all six batteries in transmitters used for flying, the bottom three are probably like new since the charging circuit draws only a small amount of current waiting for you to plug in your plane.
I learned something today! (That's a first)
