Default polarity when using Futaba receivers??

Why do all the batterys, ect, say "Be aware of the polarity when using with Futaba receivers"??? Is the polarity with Futaba supposed to opposite all other brands??
I am getting ready to fire mine up and want to be sure I dont have the polarity wrong on my Futaba 3PM fasst... when looking at the receiver should it be:

black wire, red wire
OR
red wire, black wire

Just dont want to fry anything, Thanks,

There is no "standard" polarity, so no, it's not opposite.

I believe the being careful is when charging the radio. JR, Hitec, and Futaba radios all have differing plarities in the charge ports. They aren't referring to plugging servos and batteries into the reciever, then it's all standard stuff.
