New Float Fly Rules - Download rules here or get a copy at the next Float Fly.  You must agree and sign the current rules to participate.


Notice:  Membership Application Was Revised on April 14, 2017

Changes affect Under Age 18 Members and Parents or Guardians.  Existing members are requested to use the new forms starting with your next renewal.


Cub officers have recently been very busy working to renew our Use Agreements for the field and float fly sites.  In addition to that it has been too long since our Bylaws, Safety Rules, and Operating Procedures have been updated to keep up with current Laws, Regulations, Recommended Procedures (including AMA) and Best Practices for Financial Responsibility, Data Retention, and Member Privacy.


As the webmaster I have seen a lot of  this effort because much of it is made available on the website.  I am probably not the first to thank our officers and volunteers that are contributing their time and experience to this considerable ongoing effort, but I urge all members to personally thank our officers.  All members will benefit from this effort and future officers will find it much easier to fulfill their responsibilities.

All members must have AMA membership, FAA registration and sign a copy of the Membership Application (recently updated) each year. The preferred method to renew or join the Hawks is to pay your fee via PayPal at this address: using "Send money to friends and family" to avoid the Hawks paying a service charge.  (1-3-17)

If you do not have a PayPal account, create a PayPal account at  In PayPal link your bank account. In PayPal load the account from your bank account with enough money to pay your fees. It usually takes 3 to 5 days for your PayPal account to load. Then in PayPal pay the fees to using "Send money to friends and family" to avoid the Hawks paying a service charge.  (1-3-17)


Note: Only AMA membership, and FAA UAS number along with owners name and contact information, and agreeing to sign the attendance list and follow the Float Site Rules are required to fly at the Float Fly site (Ferdinand Boat Launch) on Lake Washington. (2-7-16)


AMA Membership - All members that fly at our field, Marlow Anderson R/C Airfield (MARCA) and Float Fly site MUST have a valid AMA membership card.  AMA membership renewal is required every year.  AMA membership runs from Jan 1 to Dec 31.  If you do not  have a valid AMA membership, stop flying until receiving one.  A park flyer membership is NOT VALID at the field.  (12-3-16)


March 2nd Meeting Summary -  more detail will be in the official minutes to be posted soon.  After a lengthy review of our dire financial situation it was voted to increase dues to $70/year, retroactive to January 1, 2017. Officers were re-elected by acclamation.  Gate Code will be changed in the next 7 to 10 days pending improved weather.  Code will be emailed to all paid members.  Volunteers are needed for an AMA Cub build/Demo fly on August 4th. The club will be updating compulsory Bylaws to meet AMA recommended guidelines.  Float Fly Rules have been updated and a signed copy must be submitted with your updated annual membership application to ensure that we have current information on record.  I will have the new form on the website later today.


 If you have questions, please email or contact one of our officers.  We are updating all club activities to meet State, Federal, and AMA laws/recommendations.  Our Officers have spent a lot of time on this and more details will be forthcomming.  Your input, suggestions, and volunteer work is appreciated as it will make Lake Sawyer Hawks a better club.

Restoration of B-29 DOC  Thanks for the link Gerald and Dave!  (2-27-17)


Winter in the Pacific Northwest has many gray and rainy days.  In the Puget Sound region of Western Washington, just north of Seattle, we have the infamous "convergence zone", where prevailing southwest winds meet cold winds from the north which creates high rainfall totals.  We also see higher amounts of rain at the southern end of Puget Sound.  This February is likely to be a record rainfall, but this Tiny Whoops video, submitted by Brian looks to me like a good way to combat a bad case of "Cabin Fever". (2-23-17)


Test Photo Gallery  See About our Website for more details.  Two small Images at the top of the page in the test gallery are hyperlinks, but the page also relies on tabs and browser controls for site navigation.  Does this design work OK without the complete navigation menu?  How does it look on a smart phone?  Ultimately, content is more important.  If you have suggestions, please email me at Web Apprentice .  Thanks, Steve Black

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)

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:

RC Sport Flyer Magazine Answers Questions  (12-31-16)


Full Scale Float Plane visits April 7, 2016 Float Fly


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)
