As a result of the Appalachian ridge seminar, I started playing with IGC flight replay, to learn by watching other pilots' flights. I went to the SSA page to download flight traces from previous contests, and I managed to watch a few flights with it. I have a question though: When I downloaded the...

How is this paint is holding up on sailplanes?

Wonder if anyone has a spare Themi cable set (big plug, GPA aerial, etc.) or a complete unit. The cables for mine were lost when it was being calibrated. Let me know what you have and price, thanks. John

Has anyone successfully purchased this software recently? Say...in the last 12 months? Emails to both the support address and Matts own, listed on his SSA profile, have gone unanswered. As the Sectionals haven't been updated for some years, I don't want to pay for a licence that never...

An email correspondent asked me to explain why low-altitude thermaling is apparently so dangerous. After all, he (and I) have never unintentionally spun at high altitude, so why is it so bad to thermal down low? He suggested the answer might be of more general interest so here it is. --- It's...

Can anyone comment on the terrain for Nephi, Utah. Would it be suitable for an eastern pilot with limited XC experience in the west? Also, what have you experienced regarding typical winds. I'd be brining a Libelle 301. Penetration is limited. Thanks, 2C

This won't make much sense, unless you have followed the thread on "Death of a Gliderport". To rectify the drift, I began a new thread, Jim. Is this a slip or a crab? I agree that I have talked a lot about glider safety, over many years. :-) I disagree that I avoided addressing Russ Dervaes...

Hi, got some news .. I think many software manufacturers will adopt these kind of keyboards. They come really cheap on Amazon and Ebay , I paid mine 7,99 !!! They have more than 20 hours autonomy with their own battery, and they pair perfectly with all devices. I have just made a video of how I...

I am helping a friend put new tires on a 2002(?) Cobra trailer. The original tires are 14" Cooper 185R14C mud and snow. They seem to be really hard to come by for an exact replacement. Anyone know of other good options? Thanks in advance.

Anybody know if there are tows available in Salida, CO? A friend and I are planning a safari in late June and that would be a good place to spend a week.

I am looking for canopy frames for the Twin Astir glider. Just the frames for the front and rear seats. Naturally I need them now. Robert Mudd Moriarty, NM

For those really serious about soaring and art, here is your chance to buy a piece of history. Andrea Derujinsky (Yes, one of Gleb's daughters who makes a brief appearance in the movie) has an ORIGINAL, 16mm film version of the movie, given to Gleb by Bob Drew, the film's producer. If you are...

Why aren't we all doing this? http://youtu.be/Ln9fuR8uwIc?t=36m48s I'd give it a try if I thought I understood what the nature of the shear is that is being exploited and how to work it. I am inclined to think that whatever the nature of this "longitudinal shear", it isn't terribly commonplace,...
