Which vario has lowest latency? (Least delay to indicate thermal we pass) Anyone has done side by side tests? S

I have a deposit on both with FES system. The JS3 would arrive in 2020. The Ventus maybe 2021. Reading the POH, the Ventus may have gentler stall characteristics (according to the manual with forward CG it won't drop a wing on stall either level or in a 45 degree bank). The JS3 manual makes it...

As we know, flying in wave with the sun shining, much of the cockpit stays reasonably warm, but the feet, down in the shade, get cold. So, as I'm here at home on a cold night with a fan helping distribute the heat from the wood stove to another room, it occurred to me that something like that may...

Since winter is nearly ending and I'm doing final adjustments to my glider, I was wondering. Is it interesting to wax and polish it? I've seen a set of products he https://www.theaerodyne.com/gb/care-cleaning/188-basic-kit-for-glider-care.html D-1339

We recently purchased a Pawnee that was a sprayer. In the process of changing the airworthiness certificate from Restricted Aerial Spraying to Restricted Towing. The DAR is looking for either an STC or 337 Field Approval paperwork for the TOST hook. The EASA Form 1 paperwork will not suffice. Does...

I am working through and investigating a leaking TE line in my ship. Leak tested the TE line and it seem to be wide open. Still have some more testing to do but as of now my feeling is the leak is in the fin and completely inaccessible. I think its leaking at the back of the TE port in the fin. I...

Friends: I thought that it would be interesting to start a discussion on whether the FAI and different countries should begin to recognize 18 meters as a separate category for distance and speed records. The class has become very popular, even more popular than was the 15m class when those were ...

For a new glider pilot, do you think a DG-303 glider would be a good glider to purchase? I really like the design, and I've tried to understand all the issues that occurred around 2007 (https://groups.google.com/forum/#!starred/rec.aviation.soaring/SspUMjJ-YYo), however not sure what the end result...

OK, I understand the various interpretations of the "20 year life limit," but we don't have a rigger locally that will touch a 20 year old chute. So, apparently there are riggers that WILL offer this service. Can you lucky folks who know who they are provide some contact information? I would be...

SGP scheduled to begin first race day today launch 1:15est. Other than the SGP website, not sure where to get current updates. http://www.sgp.aero/usa2018/race-coverage/daily-race-coverage.aspx?contestID=31089

I have searched discussions on bike racks and trailers. I tend not to like the trailer hitch extension solution as stability is compromised, as well as access to the car or trailer hatches. Has anyone installed a traditional roof rack on top of a fiberglass Cobra trailer? Looking to support one...

I am looking to purchase a new (to me) XC ship. Which ones have the largest/roomiest cockpit? Not for a tall person, one with broad shoulders, about 5'9 and 200lbs. Discuss and Thank you in advance!

All, I have been looking into having my glider refinished. Casual conversations with other pilots revealed that most think a "normal" refinishing job would cost about $10k. After speaking with Gaines in Georgia, I believe that is wildly optimistic. Gaines charges $60 per hour, and he says the...

I am a member of the council for my University gliding club - fairly new compared to most of the people in this forum, but hey i enjoy it. We currently own a K13 aircraft with a (fairly) serviceable trailer. we have been offered an Acro with no trailer, and in order to buy it we will need to sell...

Does anyone know where I can purchase a 14 Volt gel cell battery. I know I can wire 2 or more in series to get 14Volt,(12 + 2 or 6 + 8 etc..) but I thought someone might know where you can purchase a single 14V battery. Thanks in advance.

I've been analyzing the IGC files from my flights and comparing them to others. Generally, in good conditions, I'm circling less than 25% of the time. Other, far better pilots than I, are circling less than 15% of the time. This means that wind data that depends on the glider flying circles gets...

I came across what looks like a really nifty pulse oximeter: http://www.scantechmedical.com/spo_medical.htm At $200US, there seems to be little excuse not to have one when flying with oxygen. Has anyone used one, or have more information on it than at this web site? I think the Minolta Pulsox-3...

I am interested in getting a sailplane and wondering what are the various ways to launch. I am aware of the traditional methods. Example= Steep downhill runway? Maybe I had too much coffee this morning!! I live on Kauai and there are no Gliders on this Island at present. Alo9ha, Les

The original question stated a glider doing 100kts with/without 100kgs of ballast. Ignoring the stalling speed for the moment, Does anyone out there think the pull-up takes more than 4 or 5 seconds? Does anyone out there think that the sink rate of the unballasted glider at 100kts is more than...
