"Hi, I think i solved the problem. I change THR_MIN value to 150 and RC_SPEED value to 100. I found this solution while searching in forums. Maybe THR_MIN change could be enough. I tested this at ground level. I will fly as soon as possible and We…"

"Gokmen, no, I don't believe this behavior is normal. From your description, it sounds like a simple issue of dirty motor bearings.  If you do a search on Google/YouTube, you can find good information on cleaning and lubricating them.…"

Motor Spin Problem

Hi All,I am disarming after 3 minutes run at ground and motors are getting little hard to spin by hand. I think it is normal. Am I right?I am rearming after about 2 or 3 seconds and sometimes randomly one motor is not spinning. If I give a little touch by hand before giving thorttle or apply little yaw after giving throttle it is spinning. By the way escs are calibrated. Is it normal? Or what could be the error?After a little moment motors is getting normal to spin by hand not showing…See More

"Most likely a faulty connection, yes. Failsafe was not trigged, but that would never give such result anyway. For some reason your log does not contain FS_BATT_ENABLE or FS_BATT_VOLTAGE , so it's impossible to say."

"Thanks Again. I am learning a lot of things. Battery Fail Safe voltage was 22.4 Volt. Last seen voltage value is 21.x volt. Could It be activated?If It was actviated Could We see it at logs? It is seen a connection problem I think. Stupied me…"

"Yes, your battery voltage is fine, it's normal to be lower under load, and even 21v/6cells=3.5vcellvoltage , no reason to crash, besides,even if the battery were depleted, you'd expect Pixhawk logging until impact. Wrote from my phone, if…"

"Your log ends midair.All signs points towards pixhawk being suddently shutdown, (brownout) the CURR.Vcc variation during flight is not *too much* or dangerous in any way, but it did vary between 5.099v and 5.175 flight, and 5.22 during flight. …"
