Can anyone supply a polar curve for a current 18m sailplane? Ideally the Ventus 2cxT, although Schempp-Hirth polars seem to be unobtainable. I already have the Dick Johnson review of the ASH-26E, so will use the polar from that if all else fails. That said, if anyone has a curve for a...

I just got a new Vertex VXA-150 handheld transceiver and wonder if anyone else who has one can answer a question for me. I programmed in two frequencies and set the radio for "dual scan" The secondary frequency was very active, but it was difficult to hear on dual scan. The broadcast was...

Last year my Winter mechanical variometer may have read a bit high, but not very much. Today however, on my first flight of the year, the vario appeared to read 400 feet high in the air and about 75 feet high on the ground.

If you are new to competitive soaring, as I am, Chester is the place to go to. Tasks were set which challenged the experts but were...

Hi All, Recently I had a couple of people ask about position outages on IGCDroid cell phone recordings. I thought I would share what is happening as this is likely relevant to other pilots and other Android cell phone GPS apps. Note: As is often true with Android, not all phone behave the same...

The RAFGSA is looking at catering for the 15M Nationals/Inter Services and have identified a number of potential caterers in the local area.

A couple of years go my partner and I bought a 1985 Discus equipped with a Westerboer VW910 & VW921 electric variometer and flight computer system. It worked well until the end of last season when it suffered a total failure, not a disgrace given the age of the instruments. Having discovered that...

The casing of the tire on my tail dolly for my Discus B, which I suspect dates from the time the ship was delivered to it's original owner in 1985, has split along the tread, allowing a bit of the inner tube to bulge out. The marking on the side wall of the tire, which is of German origin, says,...
