I found time - so Googled.
MTOW of 1370, basic empty 830, therefore payload 540.
Seat max weight limit appears to be 240 per side - 480 assuming both max weight.
60lbs for fuel - that's 10 US gallons at point of raising collective, not engine start.
Suggests 8gph at 70% - so navex to refuel and G/H on way back?
Just make it with a 17 stone examiner. That should work, no?
