Crash each time switching Hold position

[plexus]

Hi,
Since some days I have a lot of problems with my AQ.
My conditions are Hexa+ with motors 2827-35. Graupner MX20 hott , GR24.
With the last firmware V6.6.0 or R76, I have a lot of glitches in the log radio channel 0. If I come back to R75, no glitches.
But that is not the most important.
When I switch on the Hold position, the motors goes in full speed then stop or at low speed and the hexa goes down to crash on the ground, result arms and propellers broken . The action on the stick is zero.
Each time I switch the hold position the hexa goes up in the sky and I finish by a crash. Changing the factor throtlle is not the solution.

I think may be something wrong on the aq6.

Very strange behaviour.

Could you post a log from your GPS HACC, VACC and a screenshot of "altitude hold pid".

Hi christof
see GPS Hacc and Vacc. The two curves are the same (level 0,1) ? I saw on an old log a variable curve and also a binary curve.I had the blue led fixed.
The pid are standard pid.

When you zoom in after 4000, you should see the two values somewhere between 0.3 to close to one.
Did you plug the batterie, lift of, level hover and then switch to POS Hold?
Could your standard alt hold PID's or F be screwed?
I have no other 2cents.
