Hi, I bought a Tornado H920 Plus I'm very disappointed with flying times far below the 24 minutes advertised by Yuneec. With three batteries the flight time is only 9 minutes and with two batteries the flight time is 12 minutes after which I get the low battery message. Yuneec told me it's just a software problem that is being phased out Solution and that you can still fly for another 9 minutes after the message arrives. I ask the friends of the forum if the flight times are normal or if the batteries are defective. Thank you.
