After a few devistating lipo fires lately I have decided it is time to replace my lipos in my EF Yak 88" with A123 
Currently I have a FP 3000 2P2S lipo with Smart-fly pin and flag reg to a Futaba 608 2.4ghz rx and futaba 9156 servos. Also 2100 2S lipo through SF ignition reg normal switch and SF Ignition Kill for the DL50.
This system has worked well to date but I am getting worried about lipos and the potential hazards they bring, might be getting paraniod but I have seen some pretty bad results of them going wrong lately 
I want to keep it simple and light for the sake of the motor  I would prefer the switch to be failsafe like the one as I have already. I have considered the SF Power Expander route as this seems a good solution but probably overkill for a 50cc? However, am I safe using the futaba rx for the power distribution for those 5 digi servos? The A123 packs can deliver high current but will the rx became a bottleneck or does it not work like that?
Like the look of the new Fromeco 30Amp Kodiak Switch but is it just a gimmick? will other failsafe switchs work just as well?
Probably going to use a standard nicad back on the ignition but might go A123 1100 later, either straight or with an in-line diode to step down below 6v.
Any advice on the above set-up?

My two bits (penny) worth having setup a few A123 models ---
One A123 2300 rx pack --rx
one 1100ma ignition pack
This will work on any single cyl ignition -that I use.
no resistors or regs or diodes or any of that ilk----
just good wires -doubled on rx from the battery to make redundant connections,
Dual packs ?
if you wish , tho I see no need for it at all.
Oh yes use a charger which displays each cell voltage and has a balancer
it may not be necessary once cells are up to snuff but for learning the cells and having a constant visual check on anything wrong - well worth the choosing.
