how to move the guns when positioned as rear gunner?

[David198502]

hey guys!i was just online on repka3, cause all the full real servers were completely empty.however after i shot down a spit, the guy left the server and i was alone.but some minutes later another player joined and took a Ju87. i watched the plane and clicked AltF1.this brought me straight into the rear gunner's position. with the left mouseclick i fired the guns but i was not able to move it!?how do i do that?i looked into the controls menu, but didnt find the relevant buttons for it.any answers on this?

btw, i think the view of the rear gunner is pretty bad implemented.you can only look backwards and you are not able to look at the pilot.thats pretty strange.
