The Winterhawk Cup Air Race is a semi-annual air race for single-engined, piston-driven aircraft of WW2 vintage (those manufactured between 1939 and 1945).
Starting and ending at Bentwaters Field, the race covers several undisclosed airfields across the Grid, where items must be collected to prove the landing. Trophies are given to the top three finishing positions based on time, and entrants stand to win L$15,000 in prizes. Rules are sent out the week before and again on the day of the event. The race map will be sent out the day of the event for fairness.
