Ok, I understand how vortex generators disturb the airflow to allow the wing to stall at a lower speed, but there are lots of claims of better L/D for high performance planes like some jets. It seems like add bugs to your wing? Wouldn't those vortex generators reduce performance at higher speeds...

Looking for advice on improving the radio transmissions in the recently acquired Duo Discus XL. The factory installed Microaire M760-1 radio and Bayerdynamic SHM 424 microphone work fine - if you are practically eating the mic. If your head is turned slightly no voice, only carrier. Anyone know...

Looking for a serviceable 1-34 canopy/frame.

Unsolicited kudos: Yesterday was not much of a flying day so my wife and I took a long walk around the airport at Moriarty. As we approached the hangars of Mark Mocho and Bob Carlton, we saw them fiddling with an Arcus and stopped in to chat and watch. They were doing final tasks on a jet...

Perlan II glider moves to Argentina for September altitude-record attempts. Great that the project sponsorship was picked up by Airbus (where was...

Who knows if there is a rubber bumper stripping out there that will work on the Cobra trailer's top without being the expensive Cobra brand? I can't imagine it's only manufactured for Cobra.

Has anyone seen a list of presenters for this years (2016) ESA's Western Workshop? I am thinking of attending this year, but would like to know who is speaking when.

I can navigate to the Tools/Downloads page and select the file. When pressing the bottom right button the display says "Downloading" and then "Error". I've reformatted my thumb drive and tried downloading the file that I downloaded from my previous flight but today's file won't download. BTW,...

After addressing other issues with a new ship, I tackled the Power Flarm early this summer. I read the manual, talked to folks and generated a configuration file using the online flarm configuration tool on the flarm.com site. After some hesitance, the configuration loaded and the Power Flarm and...

A NEW ZEALAND ADVENTURE??? Would you or your friends like to Escape the Northern European/US Winter and come to New Zealand for a gliding holiday? The Wellington Gliding club is looking for 3-4 voluntary "summer crew" for the Dec16 to April 17 season. The club operates from Greytown in the...

I just replaced an older Becker radio with a 4201. Everything is great except that the volume is noticeably lower and I can barely hear transmissions. I am using the same wiring as I was able to plug into the old harness fine.. I transmit loud enough its just receiving is low at max volume. Any...

Has anyone come up with a clip-on mic for the radio in lieu of the boom? My DG-303 boom is a little too short, doesn't bend well, and never stays where I need it (um....that all sounds very Freudian...) I have pondered replacing the boom with a lapel type clip-on mic or even a 'through-the-throat"...

Our flying club was fortunate to have a Media Studies student make a short documentary about soaring (she flew gliders as a youth). Work like this could help to share the sport with prospective pilots. Enjoy! https://youtu.be/_uXFl0gNNEs

This is to announce that in response to requests from hundreds of you, the dynamic turnpoint file generator on my website now supports the STX format used by ClearNav. OK, maybe it wasn't hundreds, but several of you asked for it. Using my turnpoint file generator, you can upload a file...

This is the sort of dumb aloud-wondering usually reserved for the soaring off-season, but... How many days or weeks do you think it would take to fly a sailplane across the continental U.S. or Canada? Really fly it--no trailering as has been necessary during the Smirnoff Derby and Return to...

Can someone explain how you are supposed to use the SSA sailplane tracker? It seems way overly complex. You should have the option just to zoom and pan to an area of interest and see all the live tracks. However it seems you have to figure out what airport the pilot took off from and what contest...

Every time I declare a task from See You running on an Oudie to my Cambridge 302 it changes the settings in the 302 to metric. Anyone else had this problem? Thanks Dave
