I just learned there is a local club where $2500 buys you a share of a trainer airplane. So when its your turn all you have to pay for is avgas and the instructor. The idea seems promising but I don't know all the details yet like what happens to your share after you get your pilots licence and who pays for maintenance. Anyone belong to one of these clubs?
Those details would be very helpful. A lot will depend on how long it takes you. If you're going to hit the books every night and fly at least 2-3 times per week it's probably a good deal.
What's the tail number of the airplane?
What about insurance, is anything included?
Does this limit you to a certain number of hours or days?
Most people do their training in 50 hours, that would put the dry rate at $50/hr. You can train in a C-150 "wet" for around $80/hr, so it comes down to fuel economy. Figure 9 gallons an hour to be on the really safe side, lots of full rich maneuvering, lots of not leaning the mixture properly because you're relying on RPM or a crappy EGT to do so.
50 hours * 9gph = 450 gallons @ $5.50/gal = another $2,475, making your rental a total of $4975, or $99.50/hr based on 50 hours of training. So $100/hr
can be okay for a trainer, but not knowing what it is makes it really hard to say.
