Space is bound to pitch down but it's actually pitch up with the inverted controls. It's confusing and I forget if I swapped the inverted setting, but I think it's on by default so setting it like this should be right.
It will make sense when flying. Hold space to do sharp turns, use the mouse for small adjustments and rolling. Q and E on roll is really only for when I do a loop and I'm upside down, otherwise just always roll with the mouse.
