Hi, I'm hoping that someone on r.a.s. that is an expert in radio antennas and SWR meters can help me out. I just brought in a new line of 5/8 wave antennas, but the manufacturer can't tell me what length to make them. I want to cut them for 123.4 MHz so they will work well at glider...

My buddies tell me my handheld is too painfull to listen to anymore. I would put in a panel mount, but since I have a mostly carbon aircraft, where should I put the antenna? Too late to install it in the rudder, or is there a solution that would allow me to install one in the rudder?? I think the...

OK, so I made a long post in one thread about competition classes... 5U started another thread about the Rules Committee and I was really tempted to respond to Karl's comments there; but I didn't want to hijack the topic. So I'll post this in a new topic instead: I'm a low-time glider pilot...

Which clubs and commercial operations have outstanding web sites that make people eager to give soaring a try? Out of date sites with pictures that don’t include recent improvements and photographs that are obviously from another decade can’t help us recruit members. Great web sites can. Please...

Hi, I am trying to provide a very high quality sailplane tie-down kit and I need the help of this very knowledgeable group. A customer of mine recommended that I buy and sell the tie-down system that Cobra offers. I did some research and talked to Cobra about it. I came to the conclusion...

Hi all, does anybody have a usable, step-by-step decription of the LX-Polar program? The instructions that came with the manual of my LX-20-2000 are pretty useless. I have a polar curve for my glider and I am trying to calculate the factors a, b and c used to define the polar. Thanks, Uli Neumann

I am currently running for the rules committee. The polls close on October the 8th. I have created a blog so you will have the opportunity to know me better as a potential member. My intent is to provide you with the opportunity to express your concerns about soaring issues. Check it out:...

I think My B40 speaker is getting kind of weak. Even at full volume it is just barely audible, and I'm wondering what to do for a replacement speaker. Any suggestions? TIA, Frank (TA)

Has anyone thought about applications for the iPhone 3G platform in a glider? It has an excellent sunlight readable screen with touch interface that causes no loss of image quality. It has an accelerometer built in, a GPS that is probably better than spot, wireless for speech commands, remote...

Saw an article in the Antelope Valley press that said something about expanding R2505 restricted area. It had a map that covered the most used route for glider pilots flying north and south over the Ownns Valley. It extended from the present south boundry to almost Bishop., It also extended west of...

Thanks BB for the response and explanations. Whether I agree with you or not it is wonderful to have a little insight into how the rules committee thinks and to know that someone from the rules committee is listening. 5 Ugly

Does anyone have a working Cobb-Slater pellet vario that they would sell? Not the newer Cosim. They look similar.

Are there some common guidelines about how big or old kids should be before going for a glider ride? My concerns are around the safety harnesses being intended for adults... How do you ensure the harness is safe and is not going to slip around or off a kid? Are there safe ways to use a booster...

I'm looking for the book "Meteorology for Glider Pilots" 3rd International Edition by C. E. Wallington. Is anyone interested in selling a copy? -Paul S.

We have one remaing "First Flight " early release CLEARNAV system for sale. Unit is ready to ship . contact :

This has been posted before in a thread (about a lost aircraft registration document) but I thought that a unique thread on the subject would be useful. For $10, the FAA will send you a CD filled with every Airworthiness and Registration document for your glider (nicely imprinted with the FAA logo...

Its been a slow summer I know, not much as far as flight reports. Had a good short flight today. about 40 minutes total. 20 of that was spent loitering around 1000-1500 AGL praying for a good thermal to come. It didnt. Here's the report as reported elsewhe forecasts for today were looking...

Can any one point me in the direction of a used B40 variometer? Bradley

Can anyone point me to some good sources for computer modeled pressure distribution charts for sailplanes? (particularly fuselages) I have googled plenty with little results so I figured I would ask here. I found some in my OSTIV publications I have looked through, but I have most of the Technical...
