As Jason said, I brought my V1 to Angel Falls but didn't have time to use it
I am pretty sure you'll be able to fly back to base camp. It's 4000 feet and if you try to fly straight back to base camp you should make it. If you try and don't make it, you haven't got any options. The other people (like Jack ) said the trees were very soft, but with many scary bugs.
My plan was not to fly back, I can do a minute long distance flight any day here (yes, I'm from Norway) so why try to get too far away from the falls. My attached picture is grabbed from the camera right after exit. My plan was to go left right after exit, fly close to the falls and play around at the tallus you see further left and then land at the normal lz. Enjoy your flight
i wanna go back...
