If you own a CubCrafters airplane with a GTR 200 Com radio, and you use stereo headsets, I'd suggest running the GTR 200 installation manual headset test. It appears that many aircraft will have the left and right channels swapped due to a CubCrafters drawing error.
This error will only impact those who configure the GTR 200 for 3D audio or those who listen to stereo music.
