Hubsan Official Forum

Hi everyone,
a couple of days ago I was flying my Zino pro without problems when suddenly and without apparent reason it rotated upside down and rapidly crashed. I was able to recover the drone, the motors spin, the drone connects normally and there seems there are no damages. Anyhow I would like to know if it's possible to deteminate what caused the issue. In the attached log (in json format), the frame 315 was the last good flying moment, then the frame 316 is the first of the beginning of the crashing.
Can someone help me on these?

This has already happened to me on takeoff when the number of satellites was correct.
Never had an answer from HUBSAND Since then I have been flying with another much more serious and reputable brand.

Too bad, because it remains a beautiful drone but no longer has an update. (ZINO PRO PLUS).
