Mission accomplished!
The objective was to fly 43km cross country (take off in one location and land in another) and prove that this kind of long range endurance / autonomous flight / chase car was possible.
The first take off was pretty rough, the cold reduced the bungee's pulling power and impaired my ability to feel the bungee's tension. It skidded on the ground and nearly destroyed the prop.
After reattaching the prop, I took it off and tested it manual mode. It passed my stress test, so I set it on it's mission.
It flew perfectly the entire trip, and covered 52km. We landed it in a remote field a few miles south of Joplin, Missouri.

Safety note: I maintained line of sight during this flight, and had my controller close by to take manual control as needed. The altitude read over 120m, but elevation increased during flight. True AGL for the flight is 100-120m. I avoided all airports and populated areas.
