A bit of 'Airbatic' flying. American Champion Citabria.

The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. Its name spelled backwards, "airbatic", reflects this.
On this flight we got +4g and -1g.
