You bet Jim, great cells. In competition, the packs are first heated to
~50C to realize their full potential. It is at these temperatures and
higher that they offer excellent voltage retention!

Yes, for sure NiMh cells generally have lower impedance. But we are
talking about the GP2200 here. I routinely draw around 70-95 amps
from these things in my 10 and 12-cell electrics. A TD plane, fitted
with DS368s will draw a max of what, 5-6 amps?

Hi Jim,
The most important specification to consider is the cell impedence. You
might be surprised to discover that cell (larger) surface area in those
bigger NiMH cells still does not make up for lower impedence within an
even smaller NiCD cell.
Add a larger (similar) NiCD cell "and" the lo
Arne, Consider that the transmitter has very little pulse load
requirements, that is, the current drain is relatively constant so cell
resistance is a minor consideration. Therefore, the NiMH battery with its
superior capacity at moderate current is a better choice. The only downside

True enough, Simon. But if you use large enough NiMh cells, there is
more than enough ability to deliver the kinds of currents we need. I
have always thought it was silly to see people using 4-cell AA or
even AAA NiMh packs in big TD ships, then adding lead to balance. I
always try to ge
In a TX, NiMH offers superior performance given the relatively low
current consumption. On the other hand, NiMH is inferior on the RX side
when current demands are high when compared to NiCD.

Arne,
I would suggest replacing your OEM NiCd pack with a higher capacity
NiMh pack. I did it a few years ago and have been delighted. I can
just about do a complete 2-day contest with my JR 9303 on a single
charge. I am using the 1650mAh Sanyo pack built by Steve Anthony at
hangtimes.c
What Doug said. :-)

Arne,
The NiCd will have a longer life span, and the NiMH needs a GOOD
quality charger designed with NiMH features.
