QDM:
The basic costs for both the PBY and DC3 are:
Fuel : 72 Imp Gallons per. hour cruise.
Fuel: 85 Imp. gallons per. hour touch and go circuits.
Oil: Two to four Imp. gallons per. hour.
If you can get volunteer engineers and Pilots and a low insurance coverage, I can help you there, the DC3 is not all that expensive to operate.
If you wish more info e-mail me.
