Any way to change fire on deluxo?

[Ragnarr Loðbrók]

actually i only can shoot with deluxo while pressing RMB which is kinda annoying in flying mode

since you need left hand for WASD and right hand for Numpad.

I've looked into control settings tryed out a few things but didn't managed to change fire to other button

Does anyone have any clue?

Spacebutton als alternative fire key doesn't work on deluxo while flying for some reason x_x

It’s still a car even when in air, meaning whatever your shoot button for drive by is what you change

You use WASD to turn, Ctrl to lift up, mouse to shoot and switch weapon.
