PID Tuning for homemade hexacopter

dear all,

apology as I am new to this forum and I am not sure if this topics has been discussed before.

I have built a hexacopter with a homemade flight controller. The Hexacopter has 3 motors on the right and 3 on the left side. I am struggling with the gains values for the pitch, roll and yaw.

My question here, does the Pitch and Roll do have same gain values? if not, then how I can tune them?

many thanks
