Which vehicle to tow a glider trailer has been debated ad nauseum on RAS. I have always been a staunch supporter of towing with a full-size truck. After the events of last Thursday, I feel my position is vindicated. I was towing my sailplane westbound on Interstate 40 near Gallup, NM. I had...

Any suggestions? Either currently available or coming in the near future (next year or so) would be ok, I am not in a rush. Prefer it would fit in one 57mm hole. I take care of navigation and tasks with other standalone devices (full on OpenVario with its own vario/STF sensor board, and a Kobo...

I am looking for the equations to determine the speed to fly for a headwind or tailwind. I can calculate the the speed to fly for no wind based on the polar from Equation V (Page 106, 1988 US Version) in Reichmann. He gives a graphical method to determine the speeds for a headwind or tailwind but...

Question for u guys. Do you think we are going to see a massive glider fire sale after this china virus deal subsides? I wonder if this crisis and its associated lack of flying opportunities is going to convince many of the non-die-hard guys to leave the sport and divest themselves of many good...

Hi! We are trying to get new two seater from various funds for our club. Most of the funds force to buy new glider. Can you please help us a little bit with market research and suggest low budget two seater? Thank you all!

I am making a new instrument panel for my ASW27. The original panel appears to have a textured overlay that looks similar to leather. As far as I can tell the panel was made from carbon fiber over a plug and then the texture was bonded to the panel most likely using a vacuum bagging method. It...

Do users of Power FLARM need connection with flight computers like Winpilot, XCSoar, LK8000, etc, to show FLARM traffic on the moving map?

Windward has revamped their website (http://windward-performance.com/) and all sailplanes have disappeared from their website. Anybody in the know as to whether they've ceased any production, or sold off the molds etc?

Hi, FLARM has become extremely popular in several regions of the world (Europe, and Australia, and ...?), but it has not been "allowed" in the USA so far. However, there are several gliders flying with FLARM here in the USA. It is a great technology solution and safety enhancer. But technical...

Hi, I have created a couple of new help documents for Pocket PC users. Pocket PC Tips Pocket PCs are amazing devices. They offer a lot of processor power and a user-friendly touchscreen user interface in a small package. A large market keeps the prices relatively low. However, there are some...

Had the chance to make a photo of Oudie and Dell Streak 5" in direct sunlight: http://max.kellermann.name/download/xcsoar/screenshots/oudie_vs_streak.jpg

Unless you have ridge or wave nearby. A huge reduction in solar output is predicted to occur by then. http://phys.org/news/2015-07-irregular-heartbeat-sun-driven-dynamo.html

Help. I am at that age. I wear contacts for distance vision but now my arms are getting too short also. Causing headaches and queasiness when trying to read my instruments, especially the PDA. I would like to hear back from others on what decision they made on progressive vs. lined lenses...

No License, Butt, plenty of experience Florida man here... Lived in NW, flown in more than several Gliders. Been winched up, car towed up, Pawnee towed up, worked the winch on way more than 20 flights alone, lots of hours in everything from a Stearman to F-4, 3 place gliders and 2 place gliders......

This weekend Bob Carlton brought his Bonus Jet glider to Phoenix for Arizona Soaring Association members to demo and presented a fine PowerPoint / video presentation after our BBQ dinner at Turf Soaring. What a great time we all had. The weather cooperated, and although it was a tad windy, there...
