Parrot Disco with an upgraded battery will do at least 60Km. It can also be configured to fly over 4G fairly easily with very little latency. One heck of a bird if you ask me. Anyway, 34-45Km you need a wing, not a drone.
I think youre right, any suggestions? I've been going through several, several sites looking at all the fixed wings and WHOA! what a selection in this wild crazy world of UAV fixed wing. Really, all we need is a linear approx 8 miles (max) with the ability to fly back to the launch area..if possible.
