Although this may not be the perfect place to talk about this I need to talk about it.
I posted in Tech. Support but only got a general answer the first time and no answer after that.

I'm working on a couple of planes that have a lot of time and money invested in them.
My Mr. Mulligan, bashed into DGA-15, and a one of a kind Bellanca Pace Maker, 143"wing span.

The main concern is battery and switches and getting hit.
I have 8 flights on the DGA-15. I used a 3500ma battery pack with no problems.
I used a Seeker-II receiver.
The problem is I just lost a plane using another Seeker-II because of a radio hit.[]
I'm upgrading to Futaba PCM 1024 receivers and hopefully that will take care of the radio interferance.

But what about the battery system?
Should I run:
One large battery and call it good?
2 smaller batteries, 2 switches plugged directly into the receiver?
2 larger batteries, a battery backer.

Is there even a "best" setup?

Thanks Guys
