The Milwaukee County R/C Model Airplane Field is conveniently located in an urban county. The field is in 1,000 acres of Root River floodplain owned by the county, thereby offering a large flying area and resistance to urban development. The field is operated and maintained by RAMS for the public benefit.

A field license is required to fly at the field. A visitor may fly on one occasion as the guest of a current field license holder, if the visitor is an AMA member.

The field offers pit tables shaded by canopies, engine starting tables, and pilot flying stations following AMA safety guidelines.  The pit and flying areas are separated from spectators by fencing. A warming shelter is available for flying in the winter. 12 and 24VDC power is available for charging batteries.

The field sometimes floods during the spring snow melt and after very heavy rains. The flooding usually lasts for only a few days at a time. This very flooding discourages other uses from displacing the field.

• When the Root River level reaches about 6 feet, Ryan Creek (along the north edge of the field) will overflow its banks onto the field and the Root River (east of the field) will back up onto the field. This causes flooding in the east, north, and west low-lying parts of the field.
• When the Root River level exceeds about 7 feet, the entire field will be flooded and Oakwood Road floods at the nearby river crossing. This causes the city of Franklin to close Oakwood Road, making the field inaccessible by vehicle.

The field is divided into a North flying area for airplanes and a South flying area for helicopters as shown below. See the field rules for further information about flying in these areas.
