This Airport is not in the default fsx install
It uses only default scenary objects
The Small Strip is located close to Lake Haupiri on New zealands westcoast just inland from Greymouth.
It is home to Air Westcoast and the Gloriavale Christian Community

I hope it will work correctly.
But only install it by your own risk! No warranty!
