The J230 has a huge baggage area and big wing tanks, but can you use if for long cross country with 2 people?
BEW 370kg
MTOW 600kg
Usable load 230kg
2 Passengers - say 150kg,
Baggage -12 kg This seems light for what you have listed, my lightweight hiking camping gear (tent, 2xsleeping bags, 2xmats) is 7.5kg , without any personal gear, water, tie downs etc
Load capacity left is only 68kg for fuel = 94Lt, equals 3.4hrs with 0.5hrs reserve. at 120knots range of 408nm
I think you are going to get many varied responses, as we all fly different aircraft.
I'll plug the Sportstar, as that's what i've got.
BEW 321kg
MTOW 575kg
Max baggage 25kg
120L fuel capacity
100knots at 18lt/hour.
which by comparison gives
Usable load 254kg
2 Passengers - say 150kg,
Baggage -25 kg
Load capacity left is 79kg for fuel = 109Lt, equals 5.6hrs with 0.5hrs reserve. or 560nm
