Hi James,
NiCD's will deliver the most PWR on demand, but offer the least watt/Kg.
THis may require recharging at some point in the day.
AA NiMH's have significantly higher internal resistance (lack of

I've been flying with NiMH flight packs since starting in this game
(about 5 years ago) with open-class ships. The 1600-ish sized packs
seem to be the sweet spot for hydrides with regard to consistent
performance. The 2000 and above packs are (I think) pushing the limits
of capacity in the AA
No Way!! For the same package size decent (Sanyo) nicads have higher terminal
voltage under load, lower internal resistance, faster dependable charge and
discharge rates and a much longer charge retention time.
I will admit that NiMH cells have more capacity per volume than NiCads but you

The modern digital servos can draw more than 1 amp at stall.
George, you are confusing stalled with fully deflected under load. The

I've found that the best and most convenient choice for AA receiver packs are

radios and have never had a pack come close to reaching a discharged state

As far as chargers are concerned, for *all* types of rechargeable batteries,
I like the Schulze chargers (isl 6-330d, isl 6-430d, isl 6-530d, isl 6-636+,
and isl 8-936g). I would love the isl 8-936g, but definitely cannot afford
it. The isl 6-330d and isl 6-430d are very good -- value for money.
Forgive my bluntness, I've got to chime in here.
We've been blessed recently with a cornucopia of charging choices. Nearly
all are do the job just fine subject to their intended applications. Yet,
for many the usage of them takes on a nearly mystical air. Why?

How odd. I have owned three of them. They all worked just fine with NiMH

Based on your posted findings, the pack is fine to use in an aircraft. The
specs are well within the OEM's suggested (conservative BTW) operational
parameters. There is no gaurantee a new pack of similar cells would offer
better capacity values...

cycler/charger?
Have decided to purchase a cycler/charger. The Litco charger looks good but
I wont wait to be put on a list to purchase one. Any info on this or some
other battery charging/cycling system would be greatly appreciate
People always want to have 12V power supplies so I thought I'd share
this with the list:
For a nice cheap 12VDC, 8 amp (or so) power supply for your battery charger
that can be plugged into 110V at home, use an old IBM PC AT power supply.
Probably worth more to you than the computer--my dad uses

Patrick,
I just picked up a used Hobbico field charger for twenty bucks
from a pilot on the exchange. I think they normally go for around $40.00
- $50.00 bucks. Simple to use. Charges either 4.8 volt or 6.00 volt
receiver batteries, and also the 9.6 TX battery independently of one
another.
Dave,
I think that if there was enough reward for just completing the task
more fliers, other than Level IV's would do it. The only reward seems
to be the attainment of LSF level V or at least the completion of one
of its tasks. I DO consider that to be a just reward.
