<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Can't speak for the pattern sized packs, but I have been flying the Zippy/Flightmax in smaller sizes for a while. I am very impressed with them, regardless of price.</DIV>
<DIV> </DIV>
<DIV>I was distracted while walking back to the pits recently, after having landed my plane for the last flight of the day. I ended up leaving the battery in the plane, plugged into the ESC with an arming switch (which I had turned off). About a week later, I discovered my error. The battery, a 3S 3000 20C, only showed 2.2V total for the pack. I was ready to toss it, but thought I would try to bring it back to life. </DIV>
<DIV> </DIV>
<DIV>None of my Lipo chargers would touch it, so I hooked it up to variable DC supply at 1 amp for a few minutes until the pack voltage came up some. Then I hooked it up to my balance charger and charged it at a low rate (1A) until it was fully charged. I have been flying it ever since. I have another identical pack that I purchased at the same time, and the charger tells me that they both have the same internal resistance. I can't tell any difference between the two packs, except for an identifying mark I put on the one pack. Time will tell. I have not counted, but I suspect I have about 50 flights on each pack. </DIV>
<DIV> </DIV>
<DIV>I have Zippy/Flightmax packs from 1300 to 3700 mah and have not had the first problem with any of them. I am not saying they are better than anything else, but if/when I get an electric pattern plane, those are what I will purchase.</DIV>

<DIV class=plainMail>Zippy's are working well.<BR>I have 2 new Power Unlimited packs from F3A Unlimited. They are a higher 20C and very light 42 ounces all up. Most 20C packs are much heavier The power is phenomenal so far.<BR>True's 12C's are 42 ounces but my 1 remaining pack is not coming back from the winter hibernation. I know of others with the same issue. So at twice the price as the Zippy 15C's they are not a good buy. At one time the True's were a good choice but that changed when these packs came along.<BR>My choice for this year is the Zippy's 15C's for practice and the PU by FU 20C's for contest flights. The PU's are at an attractive price point for what they do. Mike<BR><BR></DIV></BLOCKQUOTE></td></tr></table>
