Budika head positions can be modified by holding down each one, moving the head position with arrows and pgup/pgdn, and then pressing F10 to save that position. Fwd view can be modified as well, effectively making it a second view position (no buttons pressed looks forward too, and that too can be modified the same way)
The clearest advantage that the 51 holds against the spitfire is its agility at high speed and ability to hold that higher speed much more easily. In this respect it's a lot like the 190 - it's at its best flying fast.
