JR gave you adequate advice reference the insurance situation of an AMA CHARTERED Club. NOW:

First, check with the laws of your area reference zoning and use restrictions. Your property needs to be OK for recreational use. If in your state you, as here in TX, have liberal tax exemptions for agriculture, timber, etc., then you should be informed of how the Model Club's use will restrict your exemptions, if any. Example: My club's property joins my property. The Club gets no exemption for 5 acres of runway, shelter, parking, etc., and that 5 acres cost more in taxes than the surrounding 95 acres, which is leased to a hay-farmer by the club and myself and is "ag" land.

You should get a specific iron-clad contract reference all ingress and egress, any improvements and their potential remains if/when the Club vacates, how far the planes may fly-over, Club/Individual responsibilities if recovering aircraft from neighboring properties, and the potential use of hazardous materials/wastes, to include current disposal of garbage.

You should be specific on requiring membership lists, annual copies of AMA insurance from the club, and that the AMA Charter requirements be accomplished to the letter, along with specific actions if the Charter/Insurance should cease. You might even want to cover the use of man-carrying machines such as hang-gliders and ultra-lights. When I sold land to my club , I deed-restricted the use of man-carrying aircraft. That precluded at least one attempt to divert the club from RC.

All kinds of things will come up, and the majority of those that are club-members will simply think of your property as another *park* for their personal use and convenience. If things get covered up front, then it is much easier as time passes.
