[JAMF]

It's an option. The "Hades" is not in the main cockpit folder by default. It takes an action of the user to copy the stick.tga file from the "Grip_Hades_475FG_431FS" directory into the main cockpit folder.

You can switch to any version, by copying that version into the main folder. Your choices apart from the 431st FS emblem are:
Grip_Org
Grip_Improved
Grip_Lockheed_White
Grip_Lockheed_Emboss

Same for the instrument panel. It's in the original readme.
