Very observant. The instruments are IAS and AOA beneath. Flap around lots when near other examples of the most enjoyable flying machine created running at high power. You should see them on an Op launch when 3 feet behind the jet ahead.
The bit in front of the windshield is the yaw vane. Tells you where to point into wind. Useful when transitioning between slow and high speed flight else you crash. Kinda.
