September 12th is the Delta Dart Build - at the SeaTac International Festival - Volunteers are needed - contact Dick Weaver.  All volunteers please read Delta Dart Build information and resources.  I updated the document on 8-5-15.


There are some issues with the current design and I have included my discoveries and comments in the Delta Dart Build document.  This is a good opportunity to share your knowledge with the younger generation and test your basic skills at building and flying a simple model.  It's also an opportunity to share your most valuable assets, time and knowledge, with the next generation which will hopefully respond in kind in the future.  Your experience and knowledge will also be added to our document to help make the Delta Dart builds a valuable community asset.  Submit comments to Web Apprentice (Steve Black)

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.


Web Site ChangesI've completed  a new "How To" page that features programming tips for the new Spektrum DX series of Transmitters and other related R/C Technology.  My next project is to document setup of a basic system with a step-by-step procedure that will serve as examples for the tricks and tips on the "How To" page.  (5-31-15)
