Best pack yet at 100 cycles. Still competition ready. A little on the heavy side. IRs were closer to 2.0 at 90 cycles and only recently has there been a slight increase. First flight 12/29/08.

General comments |
These IRs were measured during a charge when the pack was very cool. I see numbers
in the 6.4 to 7.1 range when charging after a flight. I wish I had numbers before
the "event" mentioned below.
This is my first True RC pack (long) that first flew on 2/2/08. It is still going
strong after 88 flights. I treated it well but did have one poorly planned event
that may have taken some of the life out of it. After a contest in June, I decided
to try another motor that I knew would draw more current but felt was well within
the short burst maximums. Unfortunately it was a very hot day (107F) and the pack
got very hot. After that it always gets a little squishy after each flight even
though it never gets real hot. In spite of this I believe this pack is still
capable of performing under contest conditions and I'm sure it will work well over
100 flights. I consider this a very good value as it will probably get at least 75%
as many "contest flights" as packs costing 3 times as much.

Best performing pack I have right now. A little on the heavy side but the airplane
doesn't seem to care.

I have 2 True RC packs that each have 15
cycles. Also initially always used less than 4K Mah. One pack definitely
down on power. Gets hot and uses over 4K for a masters pattern plus a
maneuver or two. **UPDATE. Both packs being replaced by True RC** |
