"Maybe, in a helicopter, not flying to an airport is the answer."
IO540 - you are spot on with this.
90% of my (helicopter) landing fees are ..er... free because I use private sites rather than airports.
The best parts of keeping your heli @ home are no hangarage charge, bowsered fuel and the convenience of going from your back yard to someone elses or to an airport only if you really must.
Unfortunately most heli maitenance shops are at airports (with the exception of Rotorspan @ Droitwich) so for maintenance you have to take the landing fee on the chin.
Alternatively you could land in the car park, put the wheels on and push in inside the airport perimeter..
that's the kind of pennypinching that made this country great!
