My s300 came today. it took only 15 minutes to get it flying(just install AA batts and charge the lipo batt)
it flies very well. you should use the limited throw(trainer mode) setting on the controller when 1st starting flying.
i got mine from ebay seller Hopmeup. it came with 2 Tenergy 130 mah batts(besides the stock battery) for free.
these batteries are fine, but are a tight fit in the battery tray.
other than that small problem, this heli was a great deal!
i got it, plus the 2 free batts for $99 shipped, and i can mail in the slip to e-flite and get a $10 rebate.
it also comes with spare blades, and tools to change them.
