Now I like to set my turret control stick so that full up fires main gun and full down fires machine gun .
How you do this is when programming stick for gun up/down elevation you only move stick up or down 1/4 in ether direction then after setup is done moving the stick full up fires main gun moving stick up 1/4 moves gun elevation up and works the same for elevation down and machine gun .
Also both my stick are self centering I like them that way .
Thanks
