Using more than one command pod

I put three command pods on one craft thinking the CMG moments would be additive. However, my craft doesn't seem and faster in angular acceleration.

"Each pod/chip can only control what is attached to them, not what it is attached to (needs verification)". I think I understand what you mean by "each pod/chip can only control what is attached to them". I don't understand what you mean the latter part of the statement, particularly the" needs verification".

Click a command pod/chip
Look at its settings
Select "Set Primary" to make that pod/chip the master pod/chip

Each pod/chip can only control what is attached to them, not what it is attached to (needs verification)

Forgive me because I'm a noob but I will try to help with what little I know.

While in craft building screen, select the Command Pod (or Command Chip), then click on the Part Properties icon on the left menu. From there you can "select as Primary" or alternatively you can "edit activation groups". Clicking on this will click on the activation groups for that Command Pod.

You can then assign each part to a specific activation group, Then in the staging menu you can select the order of stages and the parts that belong to it.

Disclaimer: I havent configured different Command Pods on one rocket or assembly yet, so I hope other, more experienced rocketeers will chime in.
