I've never had any Zippy's, but a few years back I didn't hear the greatest things about them in 1/8th scale applications. Glad you've had good luck with them, didn't mean to bash them. There are great lower priced packs (I use a bunch of Turnigy's among others myself) and I'm glad to hear Zippy's can be included in that. Was really just trying to explain why aqueel got the temp difference he did when using packs with different c ratings. Don't want anyone to be afraid of the higher c rated pack. The higher the better, with a few exceptions where ratings are inflated.
