Overall I've payed much less per hour over 23 years in a Jodel DR1050 group than to rent. That includes ALL I've payed to the group over the years. Even when it was on a C of A I payed much less. I average well over 50 hours per year.
When we've had a spell with no aircraft, I've investigated leasing. No way would it be affordable for our group of 6. Leasing needs more use than buying to make economic sense - which is why schools etc use it.
