Hexacopter sudden crash

Hi All,

We have hexacopter for testing and we made a flight in Position mode.

But about after 4 minutes, the hexacopter descent and crashed. We tried to power up and make stabilize with RC transmitter but, it has not worked. Could you give some help for analysing it?

Here is my logs.

Thank you.

From the logs i can see that when you tried to increase the throttle before the descent, motor 6 actually reduced its speed.

Did you check the propeller spin directions prior to flight?

Also, in what orientation is you flight controller mounted?

Hi nitru,

The propeller spin directions have been checked properly.

Flight controller was set no yaw orientation.

Since, it finished several flights properly and I have not received any notices from QGC, it makes me confuse.

Thank you.

Is there any chance that the too heavy weight relative to thrust could be the reason of this accident? Because it descent very stably, in that situation, any RC input has not been worked.

Thanks.

I cannot follow your question, could you rephrase it?
If you have a low thrust-to-weight ratio, this is a problem, but unless its suuper low should not cause a crash like this
