Latest Spektrum Transmitter Chart


Thanks to freechip on RC Groups for this explanation of DX6 and DX6e differences:  The "real difference" is that the DX6e is a DX6i replacement while the DX6 is a DX9 with fewer channels and a couple less functions. Which means it has antenna diversity, WireLess Trainer functions and Voice Alerts.


What the DX6e has going for it is the new Stick Mode Switch that with a single slide of this switch you can easily change modes BUT more importantly you can have your Throttle Stick spring loaded center. Making it handy for those airplane pilots that want regular stick action and then toggle to spring load the throttle stick for multirotor flying. (some like the spring throttle for MR flying.  (1-15-17)


Current Sound Level Limits -  As of August 3, 2016, King County Use Agreement allows a maximum sound level of 85 dB at 25 feet on exhaust side of gas/glow model.  (10-15-16)


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 perpared a document to help explain how we can attain sound levels at or below the limits.  Please take the time to read "Sound at the Field" and contact Randy if you have any questions.


Flying hours:

  • All Aircraft Limited to 85 dB or less Sound Level at 25 feet:

    • Monday, Wednesday, Friday, Saturday, 9:00 am to 5:00 pm

  • All Electric Aircraft UNDER 79 dB Sound Level at 25 feet:

    • Sunrise to Sunset 7 days a week

46 gram Indoor Flyer built by Don P.  Video by Brian L.  This incredible aircraft built entirely from small carbon fiber rounds and very light components and materials.


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 your 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 multicopters 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)
