There is, but you are going to have to manually mess with the panel.cfg file.  I discovered this by trial and error and the SDK is basically worthless on this subject.

Your panel.cfg file may have an entry that looks something like this (if it doesn't you will have to create it):

(VIEWS)
VIEW_FORWARD_DIR=15.0, 0.0, 0.0
VIEW_FORWARD_EYE=0.0, 0.0, 0.

The 3 values refer to pitch, bank and heading (whatever that means - the only numbers I have ever changed are the first ones).  Anyway, the VIEW_FORWARD_DIR values refer to the up/down orientation, which is probably the one you want to change. The VIEW_FORWARD_EYE value refers to a left/right orientation.

CfgEdit doesn't seem able to display these changes so I usually do it with the sim running.  Edit panel.cfg, change aircraft to force the sim to load a new panel, then change back to the original aircraft to force the sim to load the modified panel.

Got it?  Just make sure you back up.

If anyone else can provide some enlightenment on these mysterious values I'd love to see it.
