Here are a few #'s for you to kick around......
We figure 240 gal/hr (not sure what your fuel cost per gal. is)
that is based on a 2 hr flight.....1800# the 1st hr and 1400# the 2nd...avg of 1600#........
MSP on the engines is $399/hr
lets say your getting your fuel at $2.50/gal, your fuel and MSP is right at $1000/hr
your scheduled and unscheduled maintenance can really play a factor in your total cost per hr. depending on how much you plan to fly per year and the shape the airplane is in when you get it. i wouldnt put this # in stone, but you can safely add another $500/hr on the sched. and unsched. maintenance #'s based on say a 5 year outlook
again, i am shooting from the hip here.....Hope this helps you somewhat.....
PM me if you like.
