I don't recall ever seeing an estimate of the performance loss in a glider as a function of yaw string deflection. Does anyone know what it is? Ultimately, I'm wondering how much attention should be paid to deflections of, say, 1/8", 1/4", 1/2", etc., on the usual 4"-5" long yaw string. I...

I looked at his profile and his e-mail address is German ". Now I understand his mean spirited agenda. What a shame... One has to really drop low to be doing this kind of thing.

Hi, A little over 2 years ago I created a series of short training videos for glider pilots related to the use of Pocket PCs. The CD containing all the videos has sold quite well. I have now made low resolution (320 x 240 pixels) versions of all the Pocket PC Training videos available online...

I would appreciate if someone could provide me with the schematic for wiring the Terra TX760D aircraft radio. Original info was lost sometime ago. Was not able to come up with the schematic with a google search.

Does anyone know if it is safe, assuming you are properly trained in aerobatics, to perform loops, rolls and inverted flying in a 1-26E? Glider is rated at +5.3 -3.3 Gs

We're making a new winch drum. The flanges on our drum bent out a little when moving from steel to Spectra line. I'd like to know the dimensions and structure of any drums/flanges that have failed, or shown signs of failing, and with what length and type of line. Please pass this on to anyone...

My Vario shows 2 kts up when I turn it on. Hasn't done this before. Any suggestions?

My vote is LS-3a. On the 3, the leading edge of the horizontal is well in front of the leading edge of the horizontal. On this one, they are nearly coincident, as they are on the 3a. The wing is a single taper, with a curled down tip. I don't think it is an optical illusion. It also has the...

This week I had the pleasure to fly with a couple of freshly minted 2nd Lt.'s from the US Air Force Academy class of 2006. They were converting their glider time from the USAFA soaring program to civilian CFIG's. To say this young lady and gentleman are "good sticks" would be an understatement. ...

Hi, Any experience with booking systems for members and the usual single seater fleet? What do other clubs use? Thanks -- ----------------------------------------------- http://www.sgi-extremelinux.com

Thanks to all who replied either in ras or by email. No 'mechanical or electrical' intervention happened before this problem manifested itself, so I think we're left with looking at a fuel line blockage somewhere that results in such a degree of negative pressure that fuel is still drawn from the...

Thanks to Hurricane Francis, we recently (involuntarily) spent 7 days disconnected from the South Florida power grid. Even though we were far more prepared than our neighbors, it was an uncomfortable experience but we learned a bunch. Our Equipment: Coleman Fluorescent lanterns, Cheap battery...

Our club Discus has a spot for a battery just aft of the rudder pedals but the straps are MIA. Is it safe to make new straps or use Velcro for attaching the battery hold down? Brian 17

Hi, I don't believe you can switch languages without sending it back to the factory. The reason I think that is true is that they sell several versions of the GPS-NAV display. One in English, one in German, one in Italian, etc. However, I've never gone through that process, so I'm not...
