A drone: an unmanned aircraft or ship that can navigate autonomously, without human control or beyond line of sight: reference Oxford dictionary
So a dji phantom is considered a drone as it has gps tracking and autonomous flying.. Hell my robot vacuum cleaner is a drone....
It's is NOT just a military term and the term drones were about long before predators and raptors..
Back on topic.
Yes I have been looking at one for a family friend who wants to track his animals on his property, both wild and domestic.
Completely autonomous unit that has IR capability and fpv / video feed.
From what I have learned so far a hex copter (6 motors) with low kv motors and large lipos will give the run time needed.
The hardest part is the payload, for this drone it will not only do aerial recon but will have a payload too.. Noo not that
food stock for the domestic animals.. The idea is it can have a 2-3kg payload.
Just the aerial video payload is heavy with ir type video etc.
It won't be cheap, to build this we are looking at 2-3kk and most of that is covering the aircraft..
Run times are still the killer and they are noisy so you have to go so high to not spook the animals which means higher quality video equipment.
Professionally supplied drones cost anywhere up to 4-6k to buy. Heckler is right that diy is best. But still it is expensive.
