Hi All Does anybody out there have FIRST HAND experience of aerotowing with a Rotax engined SF25C Falke Motor Glider. I know these are certified for aerotowing in Europe and that a number of clubs are using them. I am interested in hearing some feedback with regards to performance, costs and...

Our club is discussing what we can do to deter birds from perching in our hangar and messing up our aircraft. Can anyone recommend a technique? Are there any methods which have not worked? The birds are small, probably swallows. Thanks Ben

Yes, according to Peter Garrison's "Aftermath" column in the November issue of "Flying" you don't need to connect your elevator control! I quote: "the NTSB report does not comment on the fact that a disconnected elevator does not make an ASW-20, or for that matter any other airplane, unflyable. The...

Hi; We spend a lot of time discussing electronic collision avoidance devices, and advice to keep a good lookout. To help the situation we could also make our aircraft more visible to those what are keeping that good lookout. Isn't some sort of visibility marking required in Europe? A search of...

The Wikipedia article on the yaw string is featured on the main page today in the "Did you know...." section as follows: "Did you know..." ....that the yaw string, a simple tuft of yarn used as a flight instrument by the Wright brothers, is still in use...

The maintenance manual for my ASW 20C glider says to be sure to only use "mineral oil" based brake fluid for the hydraulic brake system. As far as I can tell, DOT 3 and DOT 4 brake fluids are glycol based, and DOT 5 is silicone based according to my 15 minutes of research on the internet. The...

We are in dire need of a PDF or scanned version of the IAR IS-28B2 Twin Lark manuals since our manuals have disappeared. Does anyone out there could provide me with an English version or has an idea where I could find it? Thanks a lot for your help in advance, Markus Graeber Aeroclub de Colombia

I was sent a link to a gadget some college engineers-in-the-making built. http://engenius.sece.rmit.edu.au/Abstracts/Page601.htm. It tries to detect which way a thermal is based on temperature differences between wing tips. Bright boys. I have two questions; 1) Have there been other gadgets...

http://www.wired.com/autopia/2013/07/cng-airplane/ could be perfect for a club towplane since we fuel up at the club field 99.9% of the time.

Hi Jonathan- I assume that by the "ASA" you mean the Arizona Soaring Association and our basically unamimous voice against the "15 minute rule" and the one mile cylinder. First of all I don't understand the point that you are making since in your opening statement you say that "the contest was...

I have approximately 110 hours in sailplanes in the past 2 years and had no prior experience. I am evaluating used gliders for purchase.The big kahuna's in the club are pretty adamant about purchasing a first glider without flaps. My question is: Are flaps that big a problem for a low time pilot...

I heard that Avia Stroitel is buying Schempp-Hirth. And PZL-Swidnick has made on offer on Schleicher. "BTIZ" wrote in message news:IwMOa.120527$hd6.38941@fed1read05... I heard that from someone else in a news letter yesterday.. DG buys LS.. no "official"...

Who is using a motorglider as a tug? Please send details! Your location. Country. Field surface, length, elevation, temperatures. What type of tug? What gliders towed? Good, bad, and ugly of using the motorglider.

Hello, Is anyone aware of anti-collision systems (projects or products) for gliders based on GPS and short range radio? Such systems broadcast position at random times, allowing equipped vehicles (e.g. gliders) to be informed when they have a dangerous trajectory relative to other equipped...

This has been covered in these pages before, but it may be timely to post it again in view of the coming fuel price squeeze and the increased interest in winching. This Excel spreadsheet explains mathematically why a winch system comprised of lighter linear (rope) and rotational elements...

I'm surprised this spin thread hasn't produced more discussion of the flat spin. One poster told us about getting into a flat spin after several revolutions of a "normal" spin" at Minden when the Puch went flat (nose on horizon). The poster thought it was kind of thrilling, until he applied...

Just got asked this question, didn't have a quick and easy answer. How do you explain it?
