Not sure about the 8711's, but the 8411's are capable of pulling up to 5amps each, been proved over and over again on large 3D petrol airframes ask QS when he stuffed his Bulldog after browning out his Spektrum, first real high profile crash of that system that was fully investigated, but it did highlight the amp draw when you start banging the 3D surfaces from end to end, not that we do that with our jets, but at high speed I wonder what the load is? I bet its more than we think.
