Super Cub 150 on a farm strip in the West Country, 100 hours a year:
Insurance £1750
Hangarage £840
Maintenance Approx £2-500
Fuel £22/hour: £2200
Bits and bobs: £500
Not much change out of £6K = £60/hour. Doesn't take into account the cost of the capital tied up, of course.
Bloody hell it's fun, though.
