In addition to the weapons I have the flap control, the wheel brakes and the cockpit position switch (wide angle or directly at the reflector sight) on the stick. Nothing more. What you should map are the trims and perhaps manual lowering/raising of the landing gear as some older aircraft (like the I-16 or the F4 Wildcat) don't feature an automatic retraction system. For flying bombers the level stabilization is paramount.
Oh, and you should now the keys for bailing out.
