I created a Battlefield 3 Logitech G13 profile to replace the standard Battlefield 3 Logitech G13 profile to work better for me. I am using M1 for vehicles and normal infantry. Then M2 is for air vehicles. I may update it since the air vehicle setup doesn’t work the best for helicopters. I might use M1 for all but Planes.
Below are screenshots of the M1 key associations.
