Not heard much lately about this new glider development or certification. Anyone have one delivered? Interested pilots want to know :)

Is anyone interested in selling Duo Discus rides next year at various stops along the competition circuit as KS and others have done over the years - either for the benefit of the US Team, SSA Juniors, another cause, or perhaps themselves? One can never sell too many Duo Discus rides (preferably...

Sean says the US needs to go "Back to FAI Rules". Has the US EVER flown a National contest under the then current International Rules? In the May 1937 Soaring Magazine, the System for Awarding Points for the upcoming 1937 Nationals is printed. Page 12.

A flight over the most difficult terrain I've ever seen. https://www.youtube.com/watch?v=8Pp8rY08PvM

Group, My club is looking to convert a Twin Astir brake system to a Hydraulic Disk from a Mechanical Drum. Our serial number does not fall within the serial number range of the Kit that is offered by Lindner. We have the Lindner kit and will be going with a 337. My question is does anyone know of a...

As you may recall, CloudStreet: Soaring the American West was nominated for four Emmy categories. We are proud to announce that Matthew Murray and Mike Abernathy were selected for an Emmy for CloudStreet: Soaring the American West by the National Association of Television Arts and Sciences last...

Does anyone know if they are? Thanks, Bryan

We're getting closer. A fist size LIDAR for $250 thanks to the push for self driving cars. https://www.technologyreview.com/s/602503/fist-sized-laser-scanner-to-make-autonomous-cars-less-ugly/?utm_campaign=internal&utm_medium=homepage&utm_source=top-stories_2&set=602506 Cheers, 7Q

FYI... Bill Moninger's Interactive Skew-T web site now no longer requires a Java plugin. Instead it uses HTML5. For you non techies.. this means that you can get rid of the Java plugin in your browser. The HTML5 version is working well in production and beta. You can now use the site on your...

Hi All, I see that all of the JS1s currently under N- registration are flying under a Special Airworthiness Certificate. I'm wondering if it is at all possible to obtain a Standdard Airworthiness Certificate for the JS1 on the basis of its South African Civil Aviation Authority (SACAA) type...

Looking for a new or used Brauniger ALFAMFG for my 15 meter motor glider.. Steve

Are these units reliable and worth having in your glider? Are they consistent enough to trust in a real threat situation? Nick

The squelch on my Dittel FSG 50 has got to the point where it lets a lot of noise through. After a search of the Internet, I have found many allusions to the fact that this can be adjusted with one of the internal pots, but cannot find any reference of which one to actually turn. I've attached a...

Our Club has acquired a Russia AC-4C. It is a delight to fly. Its Flight Manual is missing a few pages, thus we are looking for a complete manual. I have tried Googling but that did not help. Does anyone gave a copy? Raul Boerner BFSS, Colorado

Does anyone use a safety altitude in their flight computers for final glide? If so why or why not?

A month ago, I was moving a hydraulic man lift from my house to my hangar to install remote radio switches for aircraft engine heaters. I made some forks for my tractor to pick up and move the lift as it weighs over 500 lbs. the tractor w/backhoe is 3,700 lbs. I backed the tractor onto my tandem...

Does anyone know the minimum payload weight for a Pilatus? The max gross is given in the manual, but there seems to be nothing for how light someone can be before adding ballast.

After several months of hard work a new glider club is now organized. Treasure Coast Soaring located in Vero Beach, Florida is taking possession through a lease of a 93 x 95 foot hangar that will be dedicated to sailplane operation only. Tows will be available on a daily basis, nice hotels and...

The Air Avionics Butterfly has developed an outstanding reputation as having a competitive advantage for its ability to "instantaneously" calculate wind direction. Does the CNv (with latest 3.3.3899 or beta 3.4.4089) calculate wind as quickly as the Butterfly? T8, what is the wind direction...

Polars is an app that allows you analyse and compare speed polars of many different gliders. You can alter the polar for best fit, and get the parameters for your flight computer. Watch the demo. https://www.youtube.com/watch?v=96vTiK7HRo8
