Building and Flying Balsa Model Sailplanes


All are invited to South Bay Soaring Society’s next program at 7:45pm 10/11/17 at the main Saratoga Fire Station or join us on GoTo Meeting (see instructions below).

Bob and Stephen will share their love of building and flying balsa model gliders. Bob builds the king of all balsa gliders, the Bubble Dancer designed by Mark Drela. Bob has built numerous of these gliders and he is probably the best balsa builder in our area. Stephen is not a builder, but loves to recover old balsa planes, bring them back to life with new electronics and fly them. Come hear about:

• Building in balsa, tips and tricks - Bob
◦ Design yourself, or building from plans, short kits, and kits
◦ Building light vs sturdy
◦ Thoughts on repairing balsa
◦ Enhancing with carbon fiber and/or fiberglass
• Favorite balsa builds (i.e. Bubble Dancers) - Bob
• Joys of balsa flying - Stephen
• Favorite balsa sailplanes collected so far
• How to retrofit old sailplanes to make flyable again

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 7:45pm. Anyone is welcome to attend either meeting and you can bring friends.

Yankee Soar @ October Meeting?


Hello!
Given the topic of recovering old balsa gliders/aircraft I thought I might bring my 46 year old 16 ft. Yankee Soar glider to the meeting (a picture can be found on my blog, username pricedempler). Let me know if this is appropriate or given the program, an unnecessary distraction. Either way is fine!

Price did bring his plane, one of the biggest we have had in the room. Here is a picture and pointer to his blog - Thanks, Throwbot

Using Flight Controllers in Vertical Takeoff Models


All are invited to South Bay Soaring Society’s next program at 7:45pm Wednesday, November 8th (11/8/17) at the main Saratoga Fire Station or join us on GoTo Meeting (see instructions below).

Bob Ormiston, a retired aerospace engineer, will be presenting his work in programming sophisticated flight software running on today's flight control computers. His test bed is his tilt-wing version of the Bell Aerosystems ducted propeller X-22A Tri-Service V/STOL research aircraft. This model has two rotating wings that are vertical during take off and tilt to horizontal for normal flight. He is a key contributor and user of the OpenAeroVTOL open source software project (see RCGroups Topics OpenAeroVTOL. This software is used by hobbyists, NASA and commercial R&D. Topics in Bob’s talk will include:

The development of full scale VTOL (vertical takeoff & landing) planes
What type of flight controllers are available and which one Bob selected
How to program controllers (Open Aero VTOL)
How to use open source software
How to debug Bob’s flight controlled plane
How flight controllers are used in drones and perhaps in sailplanes
Future plans for his research and modeling

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 (except December and January). The business meeting starts at 6:30pm and the program begins sometime after 7:45pm. Anyone is welcome to attend either meeting and you can bring friends.

Ornithopter Design for Flapping and Soaring Flight


All are invited to South Bay Soaring Society’s next program at 7:45pm Wednesday, February 14th, 2018 at the main Saratoga Fire Station or join us on GoTo Meeting (see instructions below).

Steve Morris spoke to South Bay Soaring Society 4 years ago and has been making progress with his ornithopters (flying planes that use flapping for propulsion) since then. We are excited to hear about this progress, especially his achievement of getting his ornithopter to soar in thermals.

Ornithopters have been flying for over 100 years but few designs have achieved high efficiency in both flapping  and gliding flight. Steve’s talk will cover the development of a series of ornithopters that have demonstrated flapping and soaring flight using wing designs different from most previous ornithopters.  The models use electric propulsion and the largest weighs 6 pounds, has a 7.5 foot wingspan, and has a glide ratio of greater than 10 to 1. This model has soared in moderate thermals.

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 (except December and January). The business meeting starts at 6:30pm and the program begins sometime after 7:45pm. Anyone is welcome to attend either meeting and you can bring friends.

If we flap the wings by servos, and move the servos directly by stirring the transmitter stick, can we fly it at the "no motor" sites?
