I have always thought that airplane owners would be wise to find a pilot
familiar with their type of aircraft who meets the "open pilot"
requirements of their insurance, and have that pilot fly the airplane for
an hour once a week. Cost to the owner compared to the cost of maintenance
should be minimal. Only hurdle I can think of is some anal FAA guy busting
the volunteer pilot for logging hours (compensation?) with only a private
ticket. Maybe I'm just paranoid.

I'm friends with a CFI in Wisconsin who used to do just that.

For a nominal fee (like, beer or lunch?), he would "exercise" planes each
week. That's how I managed to get time in an Ercoupe, by tagging along.

He built time, and the owners were happy to know that their engines weren't
being trashed by inactivity.
