I absolutely freaking LOVE how smooth these KK5040 props are on these motors. Watch my throttle in the sharp turns around the birdhouse. Notice how I'm not having to pump the throttle to manage my altitude. In my experience, this is very much a characteristic of these props on high-kv motors. I'm still in the process of perfecting how to take sharp turns with this setup, but I feel like I'm starting to dial it in.
This course was inspired by a desire of coming up with a Nurburgring-like quadcopter course around my property. For those who don't know, the Nurburgring is a famous German road racing course that is around 23 to 29 km depending on configuration. It is a famous test track for cars, because it includes a little bit of everything.
In order to avoid spoiling others' search results, I'm not putting Nurburgring in the title, though, instead calling the course the Grand Tour. I also considered calling it the Full English, but that seemed too silly.
