Copying AutoTune gains from one vehicle to another

I have several custom vehicles which are identical in geometry, mass, and propulsion systems. I would like to be able to do an AutoTune on one vehicle, and then simply copy that tune onto the others. So far when doing this, I have just been taking a screen shot of the Extended Tuning page under the Config/Tuning tab in Mission Planner, and then copying these values onto the other vehicles.

So here’s my question: Does the data on the Extended Tuning page capture all of the parameters that are affected during the AutoTune procedure, or are there other parameters that are changed too?

No, there are more. A good way to do this is to save the param file, open it in a text editor, then delete every line except the ones that start with ATC_ (attitude control) and PSC_ (position control). If you save this file with only ATC and PSC params in it, you can load it onto other vehicles without affecting the other parameters.

Thanks @Anubis. I’ll do as you have suggested.
