Guys,
Starting to get ready for our upcoming contest (May 17) at the AirStormers field in Indiantown, FL (come out it's a great field and lots of fun). I just ordered a couple Zippy Compact 4S - 3700 mah packs from HobbyKing. If you order from them it is worth checking to see if their US warehouse has the produce. It saves considerable $ on shipping.
Best, DennisT
