Good point
I've noted the giant scale flyers in my club use those "Breakout" units that easily allows the separation of the receiver and servo battery circuits, along with dual batteries for redundant operation. One of the club members has a model with four 200 inch ounce servos powering just the rudder.

Retired and the days are just too short, busier than ever!
