2010 Performance Soaring Seminar: UPDATE Everything is proceeding according to plan. The long-range forecast looks like the weather will be decent: good enough for a seminar, not good enough to go soaring! Everyone attending should have received an Evite and RSVP’d. If not, email me at...

Hi Pilots, I have tried to contribute twice using the link from the site. It seemed to work fine except no smiley face and no charges to my credit card. Has anyone else had this problem? Solutions? Thanks, Bob

Hello, Sme 10 years ago I wrote a program for DOS named "Polar Explorer" - designed for analyzing both theoretical and practical aspects of glider performance in any conditions. The program was advertised in the Soaring magazine for a couple of years by CuSoft Research Inc., and some 30 odd copies...

This video is off topic, but since it was made by a glider pilot, me, I thought it would be appropriate to share it with y'all. https://youtu.be/GNnxoXNScSA Stay safe! Branko XYU

I have been having a problem with shutting down the MZ35 engine in flight on my Russia AC-5M. The engine keeps running (dieseling) for a couple of minutes until it cools down enough and finally quits. I changed the spark plug, took off the cylinder head and cleaned the carbon deposits, but to no...

Greetings, group! Our local club has a pair of L-13s. In one of them, we recently discovered a badly-corroded elevator cable. The corrosion area was located was approx. 15" aft of the bellcrank attachment, under the port-side, aft cockpit flooring -- *very* difficult to get to. It would appear...

am curious about 16.5m wing extensions, are ailerons usually incorporated into these, or if the existing aileron/flaperon ran full span to begin with, would the roll rate suffer if the extension did not include the control surface? BTW...................Mr. Moffat inspired me when I saw him sawing...

Anyone know if the Johnson flight test for the 17m version of the LS-3 is available on the web? Thanks, Brad

Am researching the brake system for my glider project and am pretty sure a disc brake is the way to go. The cost for a suitable drum brake is about 2x what a disc brake from Grove or Matco costs, Azuza makes drum brakes, but they don't seem robust enough for my needs. I plan on using a bike grip...

When a soaring club provides towplanes to a regional or national contest, how is a club typically compensated for loaning out their equipment, or are they? Is a contest and the use of a club towplane by non-club members seen as a "commercial" operation? And if so, does the towplane need a 100 hour...

The dude's coming to town today up here in Washington. They've disable the airports webcams and barricaded (with barrels) a section of the ramp. 2 or 3 Osprey as well as they usual shell game helos are operating there. Since he's going to visit the Oso landslide, and it's location is in a valley...

After towing a Cobra for the first time a few days ago, I am now certain I want one for the HP-24. Anyone know if there are any used Cobras or Komets out there? I have cash! Brad

I haven't flown in any contests yet, but I'm wondering................to be safe and competent, how many hours or flights would be prudent to have under my belt before I went out and flew my first contest of the season? Thanks, Brad
