RE: FAA Decision Looms on Model Aircraft Regulations
If you read the Federal Aviation Act and its revisions you will find that the FAA regulates the airspace to the lower limits of its recommended minimum altitude. So it cannot regulate people flying low on their on property (500 feet inrural areas and 1000 feetin populated areas)even for full scale aircraft. So it may have a problem if it restricts models to 400 feet in all areas. The catch here is that helicopters can fly as low as deemed safe in all areas.
