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 number, or your name and contact information.  You must have your FAA Number by February 19th.  Register on the FAA website UAS Registration Q&AThe 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.  (2-1-16)


Marlow Anderson R/C Airfield Closures - Update:  Work has already started and the field will be closed frequently over the next 3 weeks while a contractor drills wells to lower the water table. 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 and below our normal flight paths, 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.  More information will be posted here as we receive updates from the project managers.  Please contact Web Apprentice if you are on-site and find out that there are changes to the planned schedule.  (1-8-16)


Update:  The field will be OPEN January 26, 27, 28, 29 (usually open Saturdays and Sundays). Steve Ashmore was at the field on Monday the 25th and talked to the contractor's Field Supervisor.  Steve will provide future updates on the work schedule, but 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.   Steve, thanks for the update. (1-26-16).


Next week the field is closed February 1, 2, 3, and 4th.  (1-27-2016)

Sound Levels and Model Airplanes - Both of our flying sites, are leased from city and county governments.  We have agreed to limit sound levels at both sites and are bound by lease agreements to follow these rules.  To minimize impact on our hobby and keep our flying sites, Randy Ling has prepared a document to help explain how we can do this.  Please take the time to read "Sound at the Field"  and contact Randy if you have any questions.

Video of the Month: B-24 Liiberator Willow Run Assembly Plant  Thanks for the link, Dan!  (1-8-16)


A Ford Airplane - AMAZING!  This was 6 months BEFORE Pearl Harbor! Henry Ford was determined that he could mass  produce bombers just as he had done with cars, so he built  the Willow Run assembly plant in Michigan and proved it.  It was the world's largest building under one roof at the  time.


This film will absolutely blow you away - one B-24 every  55 minutes. . . and Ford  had their own pilots to test  them and they had no recalls.   Adolf Hitler had no idea the U.S. was capable of this kind of thing.


Safety Note:  See Safety Page for photos of fire extinguisher locations at Marlow Anderson R/C Airfield (MARCA)Also note requirements for gasoline powered models.
