So I am in the market for a new battery for my Libelle. I was thinking it might be time to upgrade to a LiFePO4 battery. Any recommendations/reviews from the community? I've seen people using the K2 and Stark Power batteries. Any preference between the two? Thanks Peter

With all this discussion going on now, maybe someone with some knowledge or experience could enlighten us on the consequences of 10 or more sailplanes in a tight gaglge all squawking the same info. Will ATC see them all? Or will interference and/or filtering software at ATC make some or all of...

I'm going to watch my parachute get repacked this evening. The local Master Rigger is teaching a rigging class and I'm invited to watch him repack my 'chute in front of the class. Can I ask him any questions for r.a.s.? Bill Daniels

Hi; We spend a lot of time discussing electronic collision avoidance devices, and advice to keep a good lookout. To help the situation we could also make our aircraft more visible to those what are keeping that good lookout. Isn't some sort of visibility marking required in Europe? A search of...

Greetings, I have listed my Grob 102 Astir CS for sale on the Cumulus-Soaring site. The reflected price is for users of rec.aviation.soaring users only for the next week or so. Please pass along the info if you know of anyone looking for an airworthy entry level glass ship for a great price. ...

i am searching for any studies / info on the variation of rising versus sinking air & specifically the variation of the maximum rate of rising air within convective thermals. i am curious how this max lift rate changes with thermal size / total thermal energy. are larger "spikes" due to smaller...

With the larger-format 5.5" iPhone 6 Plus coming out to match the Galaxy Note 4, which of those two do glider pilots recommend for running common navigation software? ...or other pluses/minuses? Thanks, Michael

Hey all, I trailered a (new to me and a partner) glider from Ontario to Alberta last week and through the trip blew out both trailer tires on the late-80's aluminum Cobra trailer and destroyed the fenders on the trailer through the event. The first blowout (1:15am east of Madison, Wisconsin)...

Can anybody tell me the numbers to enter in the Cambridge 302 for the Discus A, or where to find these numbers? Thanks.

Our club is discussing what we can do to deter birds from perching in our hangar and messing up our aircraft. Can anyone recommend a technique? Are there any methods which have not worked? The birds are small, probably swallows. Thanks Ben

Is everybody alright?

Hello All, I am looking for real world reviews of the Puchacz (or the newer Perkoz) in the club / instructional environment. How do they hold up to daily use/abuse? Maintenance issues? How are they for ab-initio? Truth to the spin-eager rep? Any bad habits?

A question to you fine soaring fraternity, what would your response be to someone who suggested that it might be feasable to run a transponder in a glider with a pedal generator? -- BEER! So much more than just a breakfast drink!

Hi Pilots, I have a V2cxT that has the standard S-H disc brake that no longer works very well. I have been through the obvious fixes; pads, new fluid, bleed, etc. and haven't been able to bring it back up to original performance which was adequate but not stellar. I know a number of pilots have...

The Wikipedia article on the yaw string is featured on the main page today in the "Did you know...." section as follows: "Did you know..." ....that the yaw string, a simple tuft of yarn used as a flight instrument by the Wright brothers, is still in use...

I've recently started flying a Ventus2. I can't rig the thing without a lot of struggle. The trouble is, there's a cover above the spars and you can't see anything once the first wing is in. I struggle to get the second wing to fit, never knowing whether it's a bit too high or a bit too low....

The maintenance manual for my ASW 20C glider says to be sure to only use "mineral oil" based brake fluid for the hydraulic brake system. As far as I can tell, DOT 3 and DOT 4 brake fluids are glycol based, and DOT 5 is silicone based according to my 15 minutes of research on the internet. The...

I was sent a link to a gadget some college engineers-in-the-making built. http://engenius.sece.rmit.edu.au/Abstracts/Page601.htm. It tries to detect which way a thermal is based on temperature differences between wing tips. Bright boys. I have two questions; 1) Have there been other gadgets...

In discussions with other US glider pilots recently, and based on a quick search of the FARs, I believe that US pilots with PPL-Glider rating do not need any endorsements or sign-off to go cross country. If anyone knows differently, let me know. Before there's lots of advice to get training, fly...
