Heh heh... you're citing an article that Hobby King probably paid for. It's done all the time in special interest magazines. Rather than argue about it I'll let the OP do some searching on his own. If he does, he'll find dozens of articles about DOA Zippys and probably a couple other HK brands. He'll also find people who, like me, have tried both the bargain basement batteries and the slightly better ones and noticed easier takeoffs, better helicopter head speed (I fly both on my 3 cel 2200's), and better service life. And all of that is not to mention warranty service, which HK has none. Of course, he'll also find some Zippy fanboys who claim that their batteries are the same as what Max Amps sells. If someone is inclined to buy that load there's not much I can do for them.
