It is very hard to tune a brushless gimbal. Even the best tutorial found on the internet are hard to replicate because we all have different setups : cameras are different, hardware is different, Voltage input to the alexmos board is different, etc.
Let's share our PID settings to constitute an as big library of settings that works as we can. Either you will have the same configuration as someone and you can just copy the settings, either you are close to a published setup and then you can start from there to tune your particular gimbal.
-Gimbal hardware : make or model
-Camera : make and model (specify also if you have particular lenses as the weight changes with differetn lenses)
-Brushless motors : make and model, number of turns
-Power , P, I, D for pitch and roll axis
-an eventual youtube video to show your best results with these settings
-Gimbal from kamkop.de
-Camera : NEX5R with 16-50 lens
-Brushless motors : GMB 5010 - 150 turns (copies of RCtimers I think)
-Battery to alexmos board : 4S
-ROLL : Power : 120, P : 20, I : 0.17, D : 18
-PITCH : Power 50, P : 17, I : 0.15, D : 15
