[NSRCA-discussion] FW: Re: [SA] Spektrum AR9100 RX and A123batteries

Sat Feb 16 15:05:03 AKST 2008

Vince,

a few of local guys fly with A123 as RX pack.  They are a little high on the
initial voltage, but most of Spektrum receivers handles fine.
However, each cell of original size 2300mAh weighs a little more than 70
grams each.  Unless you are using them on IMAC planes, not a good choice.
I know A123 cells are now available at a smaller capacity around 1200mAh,
but they aren't cheap.
On the AR9100, I may be cheaper to run lipo and lighter.

Another interesting option below.  Who is flying the A123 batteries?  Any
feedback is welcome

Yes I have used it, if only for one flight. It works as advertised, a 
very nice product for current hungry planes. It's also easier to install 
since it does not require as much wiring. If you use A123 or Nimh packs 
they can be wired directly into the receiver, no switch and no 
regulators in line. 

As a footnote, when I used it I had two A123 lithium packs, one powered 
only the receiver as "Batt 1" and the other powered the reciver as 
"Batt-2" and also powered the ignition. I have done this mow several 
times with Spektrum receivers with no problem whatsoever. The A123 packs 
have so much capacity it seemed a shame to carry even more for ! the ign
ition.
