Intercepted
An interesting Group that is paying for the flying that it is NOT doing!
The £75/hour only just covers the fuel (about £62/hour) leaving £ 13/hour for the hourly costs, about £11 of that would go for the engine fund and so you are left with £2/hour to cover the other hourly costs.
The subscription fees from the bembers come to £9000 annualy, insurance I would guess at £3000, parking at about £2400, With a basic annual check at £1200 this leaves the group with £2400 for 50 hour checks and worn parts.
I don't think it will work in the long term!
