We are examining the Type Certiifcate for the K13. The original indicates aerobatics including spins "not approved". in 1967 Schleicher issued an AD approving semi aerobatics and spins, and printed a modified page 22 to the flight manual. Does this automatically modify the type certificate? ...

Excellent condition $275 with free shipping in the USA (new price ~$550). -- Dan, 5J

I'm curious to know if experienced glider sanders think the 3m trizact is worth the money they charge for it. I can get more than twice the number of 3000 grit 3m purple sanding disks for the same price. They don't have the foam backing - but I can fix that. Is the trizact 3000 more than twice...

Fellow US & Canadian racing pilots, The second installment of the 5 event Florida Grand Prix Racing Series is coming up on November 1-3. Friday (Nov 1) is a practice day. 5-6 gliders confirmed in each class (low, mid and high performance). As of this post, there is still room for 2-3...

The St Louis Soaring Association is interested in setting up a winch demo for our members at our field (H07) in Highland, Illinois. Are there any clubs with winches within reasonable distance that are willing to give us a demo, and possibly give ground launch endorsements? Our club is in the...

Check this out. Does it mean we might actually have capable electric self-launchers in the near future? http://www.bangstyle.com/2012/03/envia-batteries-electric-cars/

Stumbled across an interesting wind tunnel test of a Harris' Hawk (L/D=10:1). http://jeb.biologists.org/cgi/reprint/149/1/469.pdf

Should fit earlier LS-1 models, not sure about the "F" model. This includes the metal arms, the beam across the top, and the fender. $50 including shipping. I have GOT to clean out the shop... Contact me offline if you want it, Best Regards, Dave

In article Larry Dighera quotes the NTSB report: Before the collision, the Hawker had been descending toward RNO on a stable northwest heading for several miles, and the glider was in a 30 , left-banked, spiraling...

Steve Fossett is being haled by Richard Branson as "the greatest aviator in the world, he's also the greatest gliding pilot in the world" I hope via a miracle they find him alive. Given the technology he was carrying I find the chance of him being alive remote. I also noted Steve Irwin passed...

Does anybody know the current location of Simtec? The listed phone number in Hesperia CA is answered by someone else.

The movie "Eternal Sunshine of the Spotless Mind" includes no soaring and no gliders, but in one scene there is a _picture_ of a sailplane hanging on the wall. http://home.comcast.net/~johan.larson/soaring/sunshine_sailplane.jpg Can anyone identify the sailplane from the picture? It's white,...

What are the diffrences betwenn the L/NAV an S/NAV?

I don't suppose anyone has a kobold 4 Inch wheel with the 5 inch brake they would be willing to sell? as used on the schempp-hirth cirrus? Thanks, Scott Williams.

Can anyone help with references for glide ratios for basic training gliders, Blanik, K13, Puchatek etc, with full brake or half brake deployed? The internet is not very helpful for finding this information. A reference of 29 to 1 for a K6 -no brake and 7.1 full brake is about all I can...

Wish there was room for what you were all thinking... ;) I pulled the water bags out of my ASW-20B to inspect them for the first time and I was just curious what they even looked like. To my horror I saw that the string on my second wing was broken. The end of the world! I decided to pull the...

I have people ask me about gliding all the time. I always send them to the http://www.letsgogliding.com/ site and forward them links for Bruno Vassel or Balleka videos on YouTube. Does anyone else have any favorite sites that they send people to in order for them to get interested in gliding?

My club is considering implementing a wing runner checklist. The wing runner would perform this mental checklist at some point before they give the Begin Takeoff signal. "CATP" Canopy....CLOSED AND LOCKED (to the best of their judgement) Airbrakes....CLOSED AND LOCKED (to the best of their...
