5. Start to learn pid tuning =  https://docs.px4.io/master/en/config_mc/pid_tuning_guide_multicopter_basic.html

If multicopter vibrate during flying, most probably wrong multicopter configuration used. Change to any related multicopter choice given and test flight. I did mine with s500 and s500 generic. With same chardware configuration, s500 generic works better with no vibration.

6. Data link Loss Failsafe 

During our test flight with mission, aircraft return automatically during toward 2nd waypoints. When we checked, the GCS failsafe kicks in. Now we have disabled gcs failsafe.

9. Today marked the first maiden of the vtol px4 in multicopter mode. Maiden in stabilize mode. It will hover at 50%. Then after that, we want to proceed to position flight modes.  But the motors dont start until it reaches 65%. Hmm...then, watched this videos, and i should start with stabilized, then altitude hold, then position hold. And as to land, has to make sure the throttle is at 50%. Weird, multicopter didnt behave weird as this. And no warnings appeared in the qgc.
