Stegahorse,
I have problems setting views 5+6 (up-right) and 0+6 (down-right) using the keypad and setting the head (or eye) position. My work-around is to use the throttle's hat switch to look right, press either 5 or 0 on the keypad, set the head position and then save using F10. Even though I don't have the exact same problem as you, using some combination of hat switches and keyboard may work for you too.
