The "Isolator" uses two battery packs, one for powering only the Rx and the other pack for powering the servos only! Perhaps there are issues even with this system that I am not aware of but its what I have chosen to go with now and will be using it this summer in my IMAC planes.
Gary thats why this is such an interesting hobby. There are so many ways to do things but we often stick to what has worked best in the past. I never tried Reds system as I can easily drive to ElectroDynamics and Andy Loa has solved many issues with radio interference and other electrical problems. You get to trust what you know works. The first redundant pack system I used was his and that is all I have ever used since. I have used his optic isolator and from the sounds of it that is what you are going to be using. The ones I have used from both Electrodynamics and Jomar have worked flawlessly. because the receiver and the servos are not connected except by optics no feedback to the receiver can occur. Even with one servo dead shorted or stalled all the other servos will work and no feedback will occur. The thing is that since the only thing the receiver drives now is basically optics you can use a 600 ma pack and outlast the pack driving the servos. The isolator is usually designed to handle much larger currents as well. I like the ElectroDynamics one because you can piggy back them for more channels
