Sale Items

Overview
I do my best to keep a good stock of the latest high-tech gadgets.  But yesterdays latest toy is out of date today and worth less than when it was new.  The page includes a combination of new but slightly out of date items and a used items.

My plan is to keep reducing the prices on this page until all the items sell. The items will sell to the first person that orders them at the listed price. Please don't contact me with offers. The longer you wait, the lower the prices, but I have only 1 or 2 of most items - so if you wait too long someone will buy the item you are interested in before you.

Limited Availability
The items on this page are all units in my stock.  When they are sold the price is no longer available.  I cannot order additional units for sale at these liquidation prices.

Becker-AR4201-Refurb

Becker AR4201 Compact VHF/AM Transceiver (Panel mounted aviation radio) with 25 kHz channel spacing - Refurbished

These AR4201 units are used, but have been reconditioned by Becker and are supplied with their standard 2-year warranty. They look new from the front, but may have some scratches on the metal case.

AR4201 Manual or http://www.becker-avionics.com/downloads/

This small and lightweight transceiver offers 760 channels and is certified for use in VFR and IFR equipped aircraft. Even smaller and lighter than its forerunner - the legendary AR 3201 - it is ideal for installation in gliders, motor gliders and small aircraft due to its low power requirement and 2 1/4 inch round panel cutout. Due to the implementation of the most modern technology it has been possible to minimize the depth of the module, including the connector, to less than 9 inches. The equipment has an output of 5-7 Watts carrier (16 W PEP). A standby frequency and 99 memories can be easily programmed and recalled. The AR 4201 has an intercom, panel-lighting, voltage indicator, an AF-input as well as an automatic test-routine as standard functions. Two dynamic and two standard microphones can be connected without any alterations. The clear display shows the active frequency and either the standby frequency, the memory channel used or the supply voltage and also the external temperature (with the optional temperature sensor). Using the RS-232 interface, all functions can be remotely operated. With this standard feature, the AR 4201 can be easily integrated in future Becker Avionic Systems. This equipment is useful in a wide range of aircraft and is also optimal for use at flying schools and flying clubs, who place a lot of value on quick, safe and simple operation.

Compaq

CompaqAero1500 Compaq Aero 1500 Pocket PC - Used
I have purchased a few of these classic and valuable Pocket PCs from customers that traded up to other devices.  Many glider pilots still love this old PDA because its black and white display is easier to read in sunlight than newer color PDAs.  Glide Navigator II soaring flight software runs great on it.  All the units have been thoroughly tested and approved by Cumulus Soaring, Inc.

Let me know if you have any good, used power/data cables or cradles for the Compaq Aero 1500 PDAs.  I need any I can find because the power/data connectors used in the cables are no longer available.

All units include:

  • Good screen with no major defects or deep scratches - some units with defects are available at a lower cost
  • Wall charger
  • Desktop cradle (not for use in a glider)
  • Good (as far as I can tell) main battery
  • New main battery
  • New backup battery
  • Soft case
  • Stylus
  • All buttons tested
  • Serial port tested

Note: Many used Compaq Aero 1500 units have a broken cover for the backup battery.  Many require the use of tape to keep them closed.  It is not a problem.

Calendar-Segel-Bild-2013

Segelflug-Bildkalender (Sailplane Photo Calendar), 2013
by Werbe-Verlag - Cornelia Temlitz
The Segelful-Bildkalender offers fantastic soaring photos in a large format. 

Note: These calendars are somewhat out of date, but the photos are still awesome.  The calendar data is at the bottom of every page that is perforated so that it can be removed easily.  I have just a few of these remaining in stock.  $10 is a great deal for 13 very nice soaring posters.

This 44th edition of the Soaring Calendar has 13 brilliant color photos and captures the fascination and aesthetics of this wonderful sport. The reverse of each page bears further details about the how, where and when of the picture; for example: the "Adventure Sailplane" - agile in the air, and convenient on the ground; nine months' preparation for the World Championships; a Winter Dream ; the ASW 27 B - the long-distance runner. Another page tells of the further development of the Akaflieg Braunschweig SB 10. Also the first flight of Cumulus III f D-6059, nearly 60 years ago. We may not have been there at the time, but know what happened next. And there are other surprises; in large format 48 x 29 cm (18.9 x 11.4 inches) and the folding monthly dateline.

This calendar offers extremely well written and interesting information on the back of each photo.  It makes this calendar really stand out from all others. 

Note: This calendar includes a very basic calendar.  It does not have a large grid of days that can be used to write appointments or notes.  The SSA Soaring Calendar is more suited to use writing notes on specific dates.  But this calendar's large photos look great on the wall of your office or soaring club clubhouse.

Makes a great gift!

Winter
W-5001-DG1000 Winter MacCready Ring for DG-1000, 80 mm - Sale

I'm not sure how I ended up with this extra ring, but I don't need it. It is designed for use on a standard 80 mm Winter W-5253 variometer (or similar) in knots or ft/min. The ring is marked for use with an airspeed indicator that is in units of knots. A bezel ring is not included. A ring like this normally sells for $100. I am selling it for $45.

The MacCready type ring is an indispensable aid in cross-country soaring.  The ring is rotatable and is marked with speeds and a white triangle.  The chief use of the MacCready ring is to achieve the highest possible cruising speed (average cross-country flying speed) on thermal cross-country flights.  This involves setting the white arrow to the anticipated rate of climb for the next thermal.  Optimum flight performance is assured when the airspeed indicated by the airspeed indicator corresponds to the preselected flying speed to which the MacCready ring has been set.  The MacCready ring allows gliding distance and final approach  to be optimized.  Please refer to relevant literature for further details.  When ordering, please do not forget to state the type of aircraft in which the ring will be used.  If the ring is retrofitted to a variometer of older design, the original threaded ring of the instrument must be removed and replaced by a grooved threaded ring onto which the MacCready ring can be fixed with ease.

W-6001-Nimbus4DM

Großkinsky - Variable-Camberflap Ring, 80 mm - for Nimbus 4DM - Sale
I'm not sure how I ended up with this extra ring, but I don't need it. It is designed for use on a standard 80 mm Winter W-6423 airspeed indicator (or similar) in knots. A bezel ring is not included. A set like this normally sells for $170. I am selling it for $50.

Application
As is generally known, wing load and, in turn, the optimum flap positions for the varios speed ranges of a variable-flap glider changes with take-of weight.  Until now, selecting the right flap position has involved using special tables carried on board or observing a confusingly large number of marks on the airspeed indicator.  The new adjustable ring for airspeed indicators makes these complicated methods things of the past.

Features
As the illustration shows, the ring has a double scale for aircraft weight "G": and wing loading "G/F".  Four arrows can also be seen, showing the corresponding angles for the flap positions.  The number of arrows depends on the number of flap positions for the type of glider in question.  Like the MacCready ring of the variometer, the rotatable ring is simply push-fitted onto the airspeed indicator.

Use
One the take-off weight has been calculated by adding the empty weight of the aircraft, the weight of the pilot and the weight of any water ballast on board, the "G" scale is simply turned until this figure is aligned with the 0 mark on the airspeed indicator.  The arrows on the ring now automatically show the correct flap positions on the airspeed indicator scale.  Furthermore, the correct wing load for the take-off weight can be read from the "G/F" scale and entered in an electronic variometer or flight computer, if fitted.  If wing load changes in the course of the flight, due to a reduction in ballast, for example, the ring need only be turned back to the new flying weight, and immediately, the arrows show the new, flight-dependent flap positions.  The ring is calibrated for a standard preset acceleration of 1 g.  If values as high as 1.2 g should occur, as they do in high-performance competition gliding, a second ring with the appropriate values can be fitted during the flight, or changed as required.  If the  Großkinsky ring is not ordered along with a new airspeed indicator, please send us the airspeed indicator and state the type of aircraft in which it is installed, because the scales vary from model to model.  Only the 6 FMS 4 or 7 FMS 4 series airspeed indicators with 510° scales are suitable.
Note: Airspeed indicator not included.

If the  Großkinsky ring is not ordered along with a new airspeed indicator, please send us a digital photo of the airspeed indicator and state the type of aircraft in which it is installed, because the scales vary from model to model.
