Well for the first time ever after flying hundreds of drones with many different flight systems I had a fly away. During the fourth flight, while doing some turns the H decided to take a trip on it own, totally out of control. Hit the ground, broken arm, camera ripped off. Called Yuneec at 4:46 PM and talked with a very polite young man who told me to send the H back. Got an RMA # and at 5:00 PM had a UPS return label in my email. Could not ask for better service. Up till this time the H flew flawless. Hope I get it back soon.
