Next SBSS Program, 2nd Wednesday, 6:30pm, Saratoga Fire Station

I am starting a new thread using Walt's suggestion that we hold a program, rather than entertainment. Of course that could be a comment on how exciting my programs are ;-) To make even harder to categorize, RCGroups is making me call it either a Discussion or a Rave. In keeping with the decorum of our newly christened program, I call it a Discussion on RCGroups.

Next Up, March 13, 2013, Silent Auction.

Bring your excess hobby related items and make some ready cash. 10% of the final price goes to SBSS, but that is a small price to pay to get something you really want and that sometimes goes for a very good price. So dust off your stuff and bring it down. Be ready to give a short chat about it and that is our "Program" for the night. Our business meeting is at 6:30, so the auction probably won't start until at least 7:30.

See You There,

Gary Hinze Speaks on Flight Duration and the Simple Indoor Model Plane

Wednesday Night, April 10, 2013 7:30pm (business meeting at 6:30pm) Saratoga Fire Station

Gary Hinze has been modeling for 20 and has taught beginner indoor free flight with rubber models for many of them. Then in 2010 he begin moving his instructions online and flying outdoors at small parks. His talk will be largely drawn from this website on simple model aviation, from an engineering perspective. Topics wil include Integrating the three systems of airframe, motor and propeller to convert potential energy of rubber in torsion into time aloft. He will Illustrate this with examples of the planes. Duration is the central theme of indoor modeling and that sets the engineering problem. Thermal duration soarers will appreation this discussion at a general conceptual level. The purpose would be to give you an insight into the problem needing to be solved when designing, building and flying a simple free flight rubber powered miniature airplane. This differs from soaring flight in that it includes rubber power and propeller.

See You There,

Comparing Flight Simluators

Come to our Wednesday meeting at 7:30 and hear Stu, Walt and Randy discuss their favorite flight simulators for the Mac and for a PC.

Most of us know about Real Flight 6 which costs about $200 including a transmitter type joy sticks. You know not know that it has the Tom Cats airfield (Santa Clara County Model Aircraft Skypark) as one of its runways. Also it is tied closely with Tower Hobbies and Great Plains so it has almost all of their models. You also probably know about Horizon Hobby's Phoenix which include many of the Horizon Hobby planes. These are known to help beginners an intermediate fliers to learn quickly without destroying planes. Beginners who learn to turn planes heading towards in the correct direction probably pay for the simulator with the first avoided crash.

In tomorrow's discussion we will get into more subtile differences and cover other interesting simulators. The three short talks may include:

2 Min Flight
2 Extra cool features
What's good about the simulator
What's bad about the simulator
Rough idea on cost and computer setup.

Come join us tomorrow 7/10/13 at the Saratoga Fire Station. Business meeting starts at 6:30pm and the program will likely start after 7:30pm.

Thanks, Kyle

Sports Balls, Airfoils and Frisbees

Presented by Dean Godfrey Mungal of Santa Clara University, School of Engineering
Wednesday night business meeting at 6:30pm, talk starts after 7:30pm August 14th at the Saratoga Fire Station, 14380 Saratoga Ave Saratoga, CA 95070

We are excited to have Dean Mungal discuss lift and drag of objects such as balls and wings. Key to this is understanding the role of the boundary layer and flow separation. He will show that a Frisbee can be thought of as a very short stubby wing, with the addition of the Coriolis force due to the spinning motion. This will largely explain its motion when thrown. We will conclude by trying to build a better a homemade Frisbee, based upon the principles we discuss. I will supply all materials so just bring your building skills and plan on a fun night of learning and experimenting.

See You Then,

Bernouli's law, boundaty layers, & reynolds numbers

Bernouli's law, boundary layers, & reynolds numbers, AOA, L/D, trippin' turbulators ... woohoo
then mix in a flying pen shaft, double vortex, Coriolis effect, & 90 degree center of lift rotation...

Thank You Kyle, that was really interesting !

Going back to July, I wanted to thank Randy for presenting information about the X-Plane, a low cost simulator. Also Stu showed the Phoenix V2 simulator. Walt showed the Aerofly simulator. Thanks guys for a great night. Kyle

SBSS September 11th Program on John Montgomery - Our Local Aviation Pioneer

Come join us to hear John Giddings and Veronica Craven speak on Wednesday, September 11th at about 7:30pm after our 6:30 business meeting at the Saratoga Fire Station.

In the Victorian Era, when Man fist set foot up into the air, many approaches for flight were explored including kites, dirigibles, orninthopters and gliders. This was the state of technology that our own local aviator, John Montgomery built from. In 1884, he flew the first glider in the Western Hemisphere. In 1905 his gliders were the first to navigate the high air, thousands of feet up.

John and Veronica are producing a movie that will tell the story of Montgomery's race for the first practical commercial aeroplane. This film project also creates a wonderful opportunity for education, highlighting his inspiration as a young boy and his determined experiments built with his own hands from things you'd find in a farmyard. Experiments that youth could replicate today.

To help get us in the spirit, we are looking for a model of an early Montgomery plane? Has anyone in our group ever built an RC model of one of his gliders or perhaps a glider of the same era?

Don't miss September's great program, Kyle

Cakes compliments of "Nothing Bundt Cakes"

Hope everyone enjoyed the cakes, compliments of "NOTHING BUNDT CAKES" at 421 N Santa Cruz Ave Los Gatos, CA 95030, (408) 395-2959. Our daughter, Carmen, would be pleased to sample other flavors of the cakes she and her partner bake and frost on site. They're next door to Walgreens on Santa Cruz Avenue.

The Life of John J. Montgomery...Part 2

You heard about the movie, now you've got to read the book. Dr. Gary Fogel will provide us with a lecture on the life of John J. Montgomery, focusing on his efforts not only in aviation but science in general. As a physicist, Montgomery was one of the first to recognize that the laws of fluid dynamics can be applied to the river of air above us. His experiments in aviation routinely began with free flight model gliders, making him one of America's first model aviators! His understanding of airflow over surfaces and the importance of curved surfaces for lift allowed him to design efficient manned gliders, released at high altitudes above the Bay Area in 1905 - the first public flights of a heavier-than-air flying machine in America, predating Glenn Curtiss's flights with the June Bug on the east coast. Montgomery gave his life in 1911 experimenting with a radically new glider design near San Jose, a pitcheron with fixed tail surfaces.

This will start sometime after 7:30pm at the Saratoga Fire Station, in Saratoga after our regular South Bay Soaring Society business meeting. Visitors are welcome.

Gary is the co-author of Quest for Flight: John J. Montgomery and the Dawn of Aviation in the West, a biography of Montgomery a decade in the making.
or pick up a copy at the Santa Clara University Bookstore and bring it in to get signed by the author. He may have a few extra books as well.

He has written extensively on the history of gliding flight and was instrumental in preserving the Torrey Pines Gliderport in San Diego with historical designations at the City, State, and Federal levels. An avid RC soaring enthusiast, Gary also helped establish AMA's National Aeromodeling Heritage Program, preserving America's aeromodeling sites for future generations. Gary has also set several national and world records for models, and has written for magazines such as Quiet Flyer, RC Sport Flyer, and Soaring. He is a Leader Member and Contest Director of the AMA, and Historian for the Torrey Pines Gulls.

Quest for Flight by Gary Fogel and Craig Harwood

Thanks Gary and and Craig for a terrific presentation. We have a new goal. Find an model glider airfield we can name after John Montgomery. He really was the inventor of model gliding, oh yes and gliding too. We are lucky you are putting your talents into helping correct history on this great pioneer.
