I am installing a new vane style antenna for my transponder. My original antenna was located where the cg hook used to be on my discus. This location often tangled with the trailer ramp when loading the glider. Next I tried a whip style on top of my instrument panel cover. All of the self...

Richard Green of the Wycombe Test Group, High Wycombe, Bucks. UK designed and tested an auto release and offered to sell me one back in 1980. His long hand letter to me said that he was "an old age pensioner" so maybe he and his BGA certified release are something of history. The engineering blue...

I was given an older MH EDS unit to install in my Phoebus glider which I got for a song and am restoring. The glider has a bracket for the oxygen tank, but no tank is installed. The bottom is a rounded fiberglass cup, and there is a flip bracket to go around the neck. It sits behind the seat pan...

I have started tinkering around with the idea of developing a Tow-tracking for clubs to use that would not interfere with operations yet still be able to provide an upgrade to having a dedicated logger try and confirm release altitudes. My current thought is to have a cell phone app that talks to...

Why is there no IOS app for skylines?

Paragliding is the only soaring sport that's actually growing, and this pretty much explains it: https://www.youtube.com/watch?v=CjxkXNC31Z4 Or, any other vid by Jean-Baptiste Chandelier.

Any thoughts? Will the screen hold up in sunlight? It has GPS, accelerometer and a gyro. Is the 16 GB enough? Thanks, Peter

There are some designs which have no horizontal stab: flying wings for example. There are also canard setups (the speed canard, for example). For a sailplane, I was thinking about how one might design away the typical T-tail stabilizer and elevator. First of all, how much dynamic stability does...

Is this an alternative? http://www.sandia.aero/?q=STX165

VSLA? A123? Cycling chargers?? I think this subject should have it's own thread. Unlike transponders, we almost all need them.

All - I've been flying with the assumption that flying slow in cloud-streets is always a good idea. But in looking at some of my OLC flights I wonder if my logic is faulty and I'm hurting my speed. Anyone with lots of OLC or contest experience care to offer feedback? Details below... My...

Pilots all: The US rules have for several years had the option of "drop your worst day" scoring. So far noone has used it, but I for one would like to give it a try. Most of all, I think pilots will like it a lot. Yes, in the end somebody has to win, but that horrible feeling of “now I’m screwed...

The performance claims look extremely good ... is this plausible ? http://www.dg-flugzeugbau.de/mandl-absaugung-e.html KK

I was just reflecting on the Bright Hopes for the future of soaring which have appeared here in the past. What became of ... * the American Spirit / Eagle? * the Genesis? * the PW-5 / PW-6? I know a fair few PW-5's were made, but did it ever come close to the

I just received my Feb 2005 issue of 'SOARING' today and noticed a new word I'll have to add to my vocabulary. It can be found on page 22, in the caption next to the photo of the 2-33. The caption reads, 'The author's buyfriend at moment of touchdown.' How right that word can be, for either a...

Hey guys, what's your opinion on the use of mylar seals at the horizontal stab/elevator gap? Specifically for LS ships. Do people opt not to use them for fear of "lifting" tape or mylar and causing elevator effectiveness issues? Losing elevator effectiveness is certainly a valid concern, but does...

Hello All: While progress has not been as quick as we had hoped for, plans are moving forward to take the GP 14 E Motorglider to first flight very early in the new year and then for first customer deliveries soon after just in time for the beginning of the European racing calendar. For a taste of...

Fellow soaring fans, Early in the course of the SSA crisis, involving embezzlement and fraud on the part of the SSA's CFO, the entire Executive Committee committed to resign before the end of this calendar year (except Phil Umphries, who was too new to have been tainted by the scandal). Since...
