Hello,
In my last Auto mode test, I noticed an interesting issue that I hadn’t encountered on my flights before (most with default TECS parameters). After a long log analysis, when I switched to automatic mode, I saw that sudden 36 m/s air speed demand was created. As a result, my plane took a hard nose-down maneuver and began a full-throttle dive. I think the problem is caused by an incorrect parameter I entered into the TECS controller, but I haven’t come to a definitive conclusion yet.
I will do a test flight in 1-2 days. I have uploaded the log file. I would be very grateful if you could take a look and guide me to correct my wrong parameter or tuning ( if it is not enough to encounter sudden height losings).
I look forward to your recommendations.
Thanks.
My speed parameters that I changed just before I had this problem;
TRIM_ARSPD_CM was 1200cm/s by default and I changed it to 1400 cm/s
ARSPD_FBW_MIN was 9m/s by default and I changed it to 11m/s
ARSPD_FBW_MAX was 22 m/s by default and I changed it to 33 m/s. ( I think i should decrease this parameter 
)
TRIM_THROTTLE is always 45% , THR_MAX is always 100% and THR_MIN is always 0%.
