If you take a spare charged battery in the Alpha Electro then you will have the 3 hours, just need a short runway/strip to land and change them over :)
Quite true Jude, but they are rather heavy so it’ll probably have to be 1 POB. Another similar idea would be to put some batteries at (or near) different airports of course. There is no doubt in my mind that if you ask Peter, you’ll have one at or near Shoreham. And always properly charged..
