Ah, non stop only! Sorry. I'll stick with my 13 hour leg in the Twin Otter then!
The DA-42 L360 shines in every way other than endurance! No change in fuel quantity, but quite a change in consumption!
Though it had nothing whatever to do with me, a friend flew a tanked C 206 from Bermuda to Africa solo non stop. I think it was about 24 hours flying.
