I had a similar crash yesterday
I received an almost new H second hand
I am coming from Chroma so have some in site, loved it but it was stolen long story.
Anyway i went through quick start guide then followed video on compass cal
All went well.
Took off and hovered at 10-15 feet took some nice videos switched to still and took a few. Switched back to video and everything on H shut down and it fell to ground. Broke one landing gear and camera mount.
Call customer service and have RMA
Heart sick over this. I have been flying and building Drones for 5 years only incident was a DJI 550 flyaway that was never found. Last 2 years not even a broken prop now this. My Chroma was rock solid and never glitched in 18 months of flying.
Sounds to me as if this is not unheard of.
