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

IMHO. Two smaller batteries and two switches. Next would be one large battery with two power leads and 2 switches. Ive seen way more switch failures than I have seen in flight battery failure.

Thanks, do you have a favorite switch?

There will always be electrical failures??? However, I have a 1\3 Scale Pitts BIPLANE with a Q75. I have installed two receivers and two battery packs powered by a single Transsmitter. I have the top wing hooked to one receiver, and the bottom wing hooked to the other receiver. The elevator has one side hooked to one treceiver, and the other to the other receiver. The rudder and throttle are hooked to separate receivers. So far, everything has worked excellent. I cross my fingers, or some other part of my anatomy everytime I fly it.

The receiver I'm using use are $138.00 each.

For that money there Should be a better way.

If one receiver goes out How would you control the plane?

Remember if you install 2 switches you need to treat them like magnetos on a full sized plane. Check each one for correct operation before EACH flight. If you just turn them both on and take off, you could be flying with a dead switch, an if the OTHER one gets funky.......................[X(]
