Francesco, our aviation scientist in resident will be sharing with us his battery test fixtures and the knowledge he has gained from them. Francesco competes in electric launch glider competitions so we are excited for him to share his world-class experience at our next meeting. Francesco will be sharing with us:

• Common problems with batteries
• Importance of internal resistance
• When to throw out a battery
• How to inspect a battery
• An open source resistance meter
• Expensive batteries vs. cheap batteries
• Dangers from batteries.

Our sailplanes, our radios and when charging perhaps even the safety of our houses are all dependent on safe and capable batteries. Isn’t it worth an evening to learn more about this important subject?

The South Bay Soaring Society Program is held every 2nd Wednesday of the month at the main Saratoga Fire Station at 14380 Saratoga Ave, Saratoga, CA 95070. The business meeting starts at 6:30pm and the program begins sometime after 7:30pm. Anyone is invited to either meeting and you can bring friends.
Thanks, Kyle!

If any fellow SBSS members want to check their batteries' IR, just bring them with you and we'll measure them. The same goes if you are curious about the series resistance of your switch harness. Bring everything with you and we'll take care of it.

Just posted this talk by Francesco back in November 2012 about adding Telemtry to your competition sailplane and what you can learn from that. There is not video for this talk, but Francesco's slides are synchronized with the audio.

How to Build Big Wings


All are invited to South Bay Soaring Society’s next program at 7:30pm 6/8/16 at the main Saratoga Fire Station.

Richard will be talking about his latest big wing build project. It is a 16-foot, all wood and Monokote wing with ailerons and flaps. This improved wing was built to go on Richards existing custom design wood fuselage. With a bit of help, both of these bad boys will be carried into the fire station and attract strange looks from any passing firemen. In his talk he will cover:

• Airfoil Selection – Richard chose to use Rolf Girsberger’s RG-15 airfoil with its low Reynolds number. We will be asking him why.
• Design – How does a 16-foot wing keep from folding in half during a high stress winch launch? How does it fly off of a slope?
• Materials – in particular how to make a spar out of sitka spruce and balsawood ribs, but avoid modern materials such as carbon fiber.
• Building – the challenges of building such a wing straight and strong, but not too heavy.
• Test Flight – how Richard determined that his new wing was successful. How does it handle in his first months of using the new wing.

Whether you are a builder or a just a wing repair expert, I think we will all learn something new in Richard’s talk.

The South Bay Soaring Society Program is held every 2nd Wednesday of the month at the main Saratoga Fire Station at 14380 Saratoga Ave, Saratoga, CA 95070. The business meeting starts at 6:30pm and the program begins sometime after 7:30pm. Anyone is invited to either meeting and you can bring friends.

After the Crash, Repairing Fiberglass and Carbon Fiber Sailplanes


All are invited to South Bay Soaring Society’s next program at 7:30pm 7/13/16 at the main Saratoga Fire Station.

Don and Dale will be hosting a panel discussion along with showing actual examples of repairs they have successfully made on their competition class model RC sailplanes. Both have years of experience in competing and “denting” expensive gliders. Don even was a local expert working at AeroMicro Hobby Shop in Santa Clara. Topics they will cover include:

• What Causes the Need for Most Repairs
• What To Do After a Sailplane Crashes – gather even smallest parts, give it time, ask for advice, then repair or throw away.
• What Are the Common Repairs
• How to Fix a Broken or Dented Wing
• How to Fix a Broken Boom or Cracked Pod
• How to Repair a Delaminated Wing
• Finishing and Painting a Repair to Look Like New
• Weight and Balance Considerations

If you fly, you will need to learn how to repair. It will be worth your tie hearing how to do the best repair job from Don and Dale, our local experts.

The South Bay Soaring Society Program is held every 2nd Wednesday of the month at the main Saratoga Fire Station at 14380 Saratoga Ave, Saratoga, CA 95070. The business meeting starts at 6:30pm and the program begins sometime after 7:30pm. Anyone is invited to either meeting and you can bring friends.

Thanks Dale and Don for an excellent program. We appreciate that you brought in a lot of repairs to show us you covered in depth how to analyze the break like a structural engineer and how to finish repairs. We appreciate it, Throwbt

Hi Dave,

It is sitting here on my desk, but unfortunately I "wasted" the morning flying with you the boys at Brigantino Park. I have another excuse for tomorrow too, but your request is putting nearing the top of my today list. Stay tuned, that was an informative talk.

Thanks,

Come Here About The Huge Interest in Micro Gliders


All are invited to South Bay Soaring Society’s next program at 7:30pm 8/10/16 at the main Saratoga Fire Station.

Sam, John, and Kevin (aka The Kennedy Gang) will be hosting a panel discussion on the exploding field of micro gliders. These are the low cost gliders with wings spans of a meter or less. They will be bringing various gliders including the Whipit, the Aluha, the UMX Radian, and the new high tech Mini Fireworks Q Carbon. Topics they will cover include:

• Types of micro gliders
• Where to fly them
• How to launch
• How to fly
• How to land
• How to set up your radio
• Tips and tricks
• Can they thermal
• Repairing
• Thoughts on future airframe or radio hacks

If you fly, you may want to fly in small places. Come here our local experts discuss this new area of our hobby.

The South Bay Soaring Society Program is held every 2nd Wednesday of the month at the main Saratoga Fire Station at 14380 Saratoga Ave, Saratoga, CA 95070. The business meeting starts at 6:30pm and the program begins sometime after 7:30pm. Anyone is invited to either meeting and you can bring friends.

Update from John on the carbon Wing WihipIt

Kyle,

Here is a post saying that the development of the carbon wing for the Whipit will begin in September.
