RE: Discouraging problems! :(
I have had similar time, under similar conditions. Small room...adjusting pitch, practicing maneuvers while barely off the floor. Walkera 52 with carbon fiber blades cut down from 250 size. better than stock battery. I don't believe either of us would get same life while flying outdoors, or in a gym. I used the same charge and practiced on two days- yesterday and today, until recharging. Simple as that. : ) The original comment did sound like, say, a nitro flyer exclaiming that there is no way an electric heli can run this amount of time- record it, and prove it. Thanks for clearing it up. We all want to enjoy our time here.
