Model Airplane Identification -  Because our Float Fly site and Marlow Anderson R/C Airfield are AMA approved flying sites, you must have your plane identified with your AMA and FAA number. We also suggest your name and contact information in case you plane is found .  You can register on the FAA website .  Get more information at: UAS Registration Q&A.


This requirement covers all remotely-controlled model aircraft, helicopters, and drones weighing more than 250 grams (~8.8 ounces) flown outdoors. You will be asked to agree that you will limit all flight operations to 400 feet or less.  You only need to register once, but put the FAA registration number on every model airplane that you fly.  (2-18-16)


Marlow Anderson R/C Airfield Closures -  At this time the plan is to put a "Field Closed" sign on the gate when workers are on-site.  On all other days, if you are at the field when a work crew is present, please suspend flying.  After the initial work, crews will be on site occasionally to monitor equipment. Your cooperation and observance of all safety practices to avoid any possibility of accidents is appreciated.  This small inconvenience will ensure our continued use of this site. (1-8-16)


Please DO NOT talk to workers about flying if anyone is working anywhere at the field.  If you see any workers on site, DO NOT FLY The work schedule may be VARIABLE in the coming weeks, but we will continue to post updates here as we are updated by the contractor.  Thank you for your cooperation. (2-18-16).
