<p class=MsoNormal><span style='font-size:16.0pt;font-family:"Arial","sans-serif";
color:#1F497D'>I have run both this summer. The 15C’s are lighter (587g
versus 622g). They both seem to have about the same power at the start of a
flight but the 15C’s start dropping sooner. Probably not a problem in FAI
but it was a problem for me in Masters. As for longevity, it’s too soon
for me to say. I have about 45 cycles on the 15C’s and 60 cycles on the
20C’s. They have all swelled slightly with no effect on performance. I
suspect it’s mostly because of the deep discharges that happen in the
Masters schedule. Hope this helps. BTW, I also have some TP 20C’s and
those are slightly swelled as well. Power is similar but the TP’s have
the most power left for the last few maneuvers in Masters. My TP’s weigh
about 600g with the connector and Velcro. Hope this helps.<o:p></o:p></span></p>

<p class=MsoNormal>I noticed that most are running the 15C 5000 packs but
these seem to be in stock infrequently. Can anyone comment on the performace
of the 20C 5000s from Flightmax. <o:p></o:p></p>

<p class=MsoNormal>I know there must be reasons that the 15Cs are more
popular....just not sure what they are. I would have though the 20Cs would be
better as someone reported that they are only 10gms more than the 15Cs and
would provide a bit more power. Additionally I noticed the TPs are
20C...not 15C.<o:p></o:p></p>
