Out of curiosity, how does any RC club come up with that kind of money for a runway?
Fund-raisers, private donations and I think you can get some assistance from the AMA.
I fly at a club that is located in a city park that was set aside for model flying (and model flying only). A previous club president got the city to agree to pay for half of a paved runway, got the AMA to agree to donating some funds and the club would have had to cover the rest, which was very doable. He took it to the club for a vote and was voted down.........badly. Most club members felt that pavement was just too hard on airframes and the rest, just did not want to spend any club money. Go figure.
