I don’t have a clickable cockpit game, but it feels somewhat counter intuitive to me to let go of the stick and grapple with the mouse to click on a region in the cockpit. (Unless you’re lefty, or, you can use a mouse setup to be lefty).
if I remember correctly our dburne (RIP) had a finger attached clickers that can be used for clickable cockpits, but don’t remember the name of the product.
