Cool, welcome! I just started this community today as I'm starting to post photos from a festival this weekend.
I'm on the west coast, but I've traveled around for kites quite a bit. There is a festival in Long Beach Island, NJ coming up soon (Oct 10, Oct 11). https://lbifly.com/ There will definitely be quad kite fliers there.
The black/red is my own build called Essentials. I have details about them on my website, including open source build plans and 3d printing models for fittings: https://watty.us
