Hi @Shady_Zahran ,
also in the laboratory where i work wehave a big drone (a hexacopter with 1m of diameter) and we had few problems with the tuning.
But in the logs that you posted i can see only that you armed the drone but didn’t fly, moreover while the drone is on the ground i see that the roll and pitch angles changes a lot.
Do you have a flight log?
no, i flew twice but only for a few seconds, then it fell down. i will upload the flight log and post it for you. i noticed that the vibration is too high so i am trying to design a damping mechanism, i think if i solved this one it will fly.
