Russ seeing you are thinking about all those animals with an aim of wrecking an aircraft.
Just for those which continue to insist I am thinking of an electric fence would be good.
We can get 4 specialised very lite posts for electric fences, small energiser which runs on torch batteries they will run for about 5days the string is not a burden all that will pack in a little bag when you get there not much work to construct that fence. I am in the process of putting all this together just for aircraft safety.
I hasten to add three more animals to the list:- goats, horses and pigs.. Electric fence keeps all at bay..
