Guys I've been running the new Power Unlimited packs all season long. We like to refer to them as PUXFUpacks. At the Nats I was really pushing them hard with an average of 4200 mils pulled on my six competion flights. I'm happy to report that they are really hauling the mail so far. I couldn't be more pleased with their performance. They can take abuse and not have any lasting effect.I also had some Zippy 5000 15C's and a Rhino 4900 20C packs and these are significantly more powerful. They are the only packs I will use in competition. I'm running an AXI F3A in my Integral with a Rasa 20.5x14 prop. My WOT amps are about 80. It's a very powerful setup and allows a wide open faster style that I like. I'm flying the AMAMasters schedule and it's long and these packs deliver all the way to the end.
They have the advantage of a lower weight with a higher C rating which makes a big difference. Mike
