My guess would be around twice the cost of a C-172, per hour. Twice the
horsepower, twice the fuel burn, twice the insurance, twice the
maintenance, twice? the purchase price.

However, the cost per mile or per pound of cargo would be less than
twice the C-172 price. Which cost do you want to know?

It's useful to know recall rules of thumb.

The first is that fuel burn is 0.5 lb/hp/hr. For an IO-520 at 285 hp
running at 70% power, that's about 16.6 gal/hour.

The second is that fuel costs are 1/3 total costs. This rule may
overstate costs when fuel prices rise quickly, as they recently have.

Tried to find those information but I can't.
So I would be very grateful if someone could provide me with these
information.

Thanks!
