New Race

This time New York. You find Grand Canyon here: https://flightsim.to/file/7487/grand-canyon-airrace

Starts in Central Park. I have added a flight plan in the zip file.
As usual extract the folder into your Community folder.

RING COLOURS
The track starts with a RED so it is easy to see.
The track is based on YELLOW rings for the first section and turns GREEN when the track is overlapping to make it clear what colour to follow. The track ends with two BLUE rings.

THREE NOTES
1. When approaching Empire State Building, keep left and turn at the TOP RING on the LEFT side. Then follow the building downwards clock-wise (right). 
2. Dependent on your graphic settings, the idea is to go under the Brooklyn Bridge and turn sharply or make a looking and then continue towards the Brooklyn Heights. Yes, there is a collision detection under bridges, but in this case, you should only loose some speed and not plunge into the water.
3. Tip! If you want to continue after the BLUE rings, bank left and dip and you will align perfectly with the yellow rings at Battery Park continue around the Financial District.


THE ROUTE
You start over Jacqueline Kennedy Reservoir (large lake), fly over Metropolitan Museum of Art, Bow Bridge (The Lake), Central Park Zoo and down 5th Ave passing the Apple Store. Going up over The Rock and dip directly to Times Square, passing Macy's and going up on the LEFT side of the Empire State Building, circle the whole building clock-wise. Continuing 5th Avenue passing Flatiron Building, turning at the Washington Square Park, taking a turn passing over the Lower Manhattan going between the World Trade Towers. Diving and following the West St, banking left at the Battery Park following the coast line passing all the Piers. At Pier 17, go under the Brooklyn Bridge with a looping (?) fly over Brooklyn Heights, Dumbo and then going under the Manhattan Bridge onwards Pike St. Rings turn GREEN while you pass over China Town and Tribeca, take a turn around the One World Trade Tower, towards the Seaport and end flying through the skyscrapers of the Financial District.... through the BLUE rings...

(No) Collision
I have not, yet, found a way to enable collision detection. Using the Collision element in Blender when exporting with blender2msfs, does not seem to work. Setting the ring as a road creates the collision, but not possible to fly through the ring, in the same way you cannot fly under bridges either. I tried to place cubes, plates, cylinders etc. on the outside with the road element, but it does not work consistently.


Have fun!
