I used a drone to hang a leader line for a high rope for my nephews swing. I'm talking like 60-70ft up. It was an amazing swing with a massive pendulum effect.
Highly recommend using a drone for this, just don't get it stuck up there.
Edit: at my last apartment, I did put a node about 35 feet up a pine tree. I used a 10ft PVC pipe, half inch, and lashed it to the center trunk so it stuck out the top a few feet to get solar. Worked really well.
