Cheap as chips...
I do believe that there is a general lack of understanding about the costs of operating old machinery.
My 2 old wooden birds are not on Public Transport CofA's and are thus not insured for hire or reward either - very expensive indeed.
Nevertheless - I reckon they cost me £300+ per hour each to operate, based on 50-75 hours a year between them.
The Chippie - with its raft of AD's, aint the cheapest toy in the box to operate either.
Sounds a good deal to me, especially if the price reflects a well maintained, sweet aircraft and not a dog.
THe other option for all is a ride in a Tiger at Old Warden when The Moth Club have their annual Charity Weekend. It ain't dear. It is also a wonderful spectacle - like moths round a light bulb.....!
