I am new to the larger gassers and am in the process of setting up a 88" Wild Hare Edge 540 that I aquired from a fellow club member. I am looking to use a setup similar to what a few guys in my club reccomend so that it will be easier for them to assist me in troubleshooting in the future. Here is what I am looking to use.

Radio - Futaba 7C
Engine DLE 55
Servos Hitec digitals (not sure of the model, but what the plane was previously flown with)
Batteries - 2 Each, Dual Battery Setup - Fromeco Li Ion http://www.fromeco.org/products/01frc2600-100/ with dual JR Leads
Switches - 2 Each already in the plane.
Regulator - 2 Each MPI MKIII http://www.troybuiltmodels.com/items/MPIR6VNEW.html
BEC/Kill Switch -1 Each http://www.troybuiltmodels.com/items/WRCIBEFV2.html

My question are:
With Dual leads on the batteries and on the regulators do I need 2 additional switches for the redundancy.
How would you wire this setup?

Thanks

I vote to ditch the regs and use a couple of A123s. (WrongWayRC rules !) There are switches available with a Deans in and multiple JR outs. [link=http://www.smart-fly.com/Products/Switch/switch.htm]Smartfly[/link]

Pick some sort of ignition battery eliminator and loose the ignition battery too.

I second this post. A123 2 cell needs no regulator and that is just that much less to fail on you. One note though, I think you will find that the ignition for the DLE 55 requires 4.8 volts max. So the 4 cell NiCad will be what you will want to use on that. I use 2000 mah min. I never use a regulator on the ignition. They pulse and can interfere with the ignition operation.

An IBE will let you fly on only two packs, would be fine on only one pack but two fulfill the redundancy need.
I know that Richard at [link=http://www.wrongwayrc.com]WrongWayRC[/link] has an ignition power lead that drops the voltage to keep the ignition happy.
