AG1 - Doors/Hatches (you spawn at a airport press 1 to open, if you spawn on a approach press 1 to close when you land it)2 - back gunner hatch (wont open if you close the hatches with ag1)AG3 : Press this when you want to use the rear gunner’s station. It will freeze out the plane’s controls, activates a gyro, and lets you control the MG15 to fire at enemies on your six.AG4 : You will notice engine smoke effects sometimes. Looks neat, but still… you can switch them off with AG4. The build has realistic weight, power and fuel load; the smoke effect unfortunately uses up quite a bit of fuel… and so it’s really only useful to take pictures.AG5 - nothing yet..AG6 - Left Engine/First Engine ignitionAG7 - Right Engine/Second Engine IgnitionAG8: Nav Lights/ Wing Lights
