I wanted to go backwards. I moved SIDEWAYS towards the twin 5" guns....
Going backwards without brakes on? Also new to me....
Turning CV?
Now, when it comes to 're-spotting' planes on the CV deck, going backwards has nothing to do with brakes. Brakes are for stopping. A touch of throttle will move
the A/C backwards (no more than a little). Be sure to use your rear view and rudder. The rudder will help adjust right or left. If you don't want to move then make
sure your throttle is at 0 (or, better yet, kill your engine). G'luck!
P.S. I don't see this as a 'bug report' issue, imo, since it involves using the 109 in a manner that it wasn't designed for in game.
