Cause a C310 lifts more!! especially fitted with a VG kit. Did my initial multi on the party bus and then lots of hours since then in a C310.
Most weigh around 1700 empty, plus pilot say 1800. On a two hour leg you can lift 480kg! (2280ZFW, 2565MTOW) plenty of weight for five pax plus day bags! try doing that in a party bus.....
Also the speed! 385NM in 2.1hrs airswitch, including getting established on track, circuit etc hehehe (yes I had a small tailwind but I did the outbound in only 0.3 more..)
BTW fuel in Borroloola around $2.70lt
