Alas, the FAA rules here in the US prevent us from inviting the visitors in to see an aerobatic competition. Providing for spectators moves the event into the "airshow" category of regulation, increasing the requirements for on-site emergency services, crowd control, and other safety capabilities, all of which greatly increase the cost. Aerobatics is regulated as a sporting event, for the benefit of the participants, with minimum provisions for spectators.

Best of luck,
