Here is what I found after a quick Google:
T&G Flying Club, Inc.
Aircraft And their requirements for rental:
Rental Requirements
Assuming 28 gal/hr per side at $4 per gallon, yields a fuel cost of $224 per hour. Assuming roughly 30 hours (my guess based on 20 hours for a 182) of labor for a 100 hour inspection at a rate of $60 an hour, you can add $18 per hour. That puts us up to $242 per hour plus parts (I wouldn't hazard a guess at that without a VERY thorough pre-buy inspection). And don't forget insurance and hanger fees (if you choose a tie down, assume you will be repainting about 5 times as often: McAllen sun is murder on paint). Guessing about $15000 per year. So if it rents out 30 hours per month that adds another $40 per hour.
That puts costs over $300 per hour.
