Our An2 is a German reg public cat example therefore still flying.
Fuel only cost is around £200 per hour (200l of AvGas), although maintenance costs suprisingly little as the Russians designed them to last. Parts are relatively cheap if you pay in US$ and Vodka.
I am always happy to go flying wih anyone who wants to log some P1S time on a cost sharing basis. Most share it with a couple of others and the cost comes right down for each of us.
Oh, and I'm always looking for a good excuse to fly it!
