I have a futaba 6ex transmitter with the matching receiver
I am about to buy a Hanger 9 Sbach & it is clear the servos will be working hard
I am using spectrum A6180 servos
These may not be high voltage but may use a lot of power from the standard receiver battery leaving the receiver short of power. If that cuts out then presumably the lot hits the deck.

Is it possible to guard against this in a similar way the motor cuts out before the receiver on an electric plane

How do i provide this extra power for the servos. Do i replace the normal battery with a different bigger one & if so how do i know what size to buy.?

Or does one put a dedicated battery for servos only & if so how does one wire it into the system & still retain some safe ty feature
Thanks
