To debunk the previous e-mail's pejorative comments, I actually have a data set to report. I am flying a 9 lb, 31 3/4 oz Genesis and am using the lighter Flightmax 15C 5S-4400 mah packs so my airplane will make weight. I am an engineer, but am not so anal as to record all their weights and charge/discharge cycles (who would do that?), but can report that the 4400's have enough power at the end of the Master class maneuver sequence to pull the 1/2 Square Loop w/ Two 1/2 Rolls Up with authority.<br>

It's just hard for Ron to write anything long since he has to translate from his native Latin.<br>

Yes. Nobody can match Mark's pithy comments.<br>

<br>
I've been running both and would encourage you to get the 20C, or<br>
even the 25C if you can handle the weight.<br>
<br>
15C - typically run between 1180-1205gms for a pair (with connector<br>
and Velcro, etc). Power is good, but NOT if they're cold, or even<br>
cool. I have 50 flights on 4 different sets and I would argue that<br>
most are on their last legs. They still fly the P schedule fairly<br>
strong, but F is a stretch, and they are getting hot and puffy now.<br>
<br>
20C - I have 2 sets and 1 is 1210gms and the other is 1245. BIG<br>
variance. But they seem to handle the load better. One is still<br>
getting hot/puffy though with only 30+ flights on it. THIS btw,<br>
is the main issue I think with the zippy packs. Inconsistency.<br>
Some are great, some are fair, some suck. You get a little of<br>
what you pay for. I'd say there's about an 85% hit ratio with the<br>
flightmax packs, meaning that you should expect about 1 in 5 to be<br>
pretty poor. Still a good value though.<br>
<br>
25C - these are heavy...about 1300gms per set, but they've been<br>
running very strong, very cool, and staying rock solid (no<br>
puffiness yet) with about 30+ flights on 3 sets. They still have<br>
the issue of not delivering great power when they're cool. At the<br>
nats we noticed that the Zippy's seem to be more temperature<br>
sensitive than the TP batteries. The TP were down a little when<br>
they were cold, but the zippy's were down a LOT. When they were<br>
warm, they held their own with the TP batteries. Not sure what the<br>
reason for the variance is though.<br>
<br>
This was my first year flying E, so that's really all I have to<br>
offer. For reference, I was running a Hacker 14XL with a 21x14<br>
prop flying 7.5min flights (fairly strict about that).<br>

Subject: [NSRCA-discussion] 15C vs 20C Flightmax batteries<br>
<br>
I noticed that most are running the 15C 5000 packs but these seem<br>
to be in stock infrequently. Can anyone comment on the performace<br>
of the 20C 5000s from Flightmax.<br>
<br>
What's the weight, performance and longevity compared to the 15Cs.<br>
<br>
I know there must be reasons that the 15Cs are more popular....just<br>
not sure what they are. I would have though the 20Cs would be<br>
better as someone reported that they are only 10gms more than the<br>
15Cs and would provide a bit more power. Additionally I noticed the<br>
TPs are 20C...not 15C.<br>
<br>
I'm new to the e-scene...so please ignore the ignorance.<br>
