New Goddard Cables for Connecting an SN10 to a FLARM or PowerFLARM
The SN10 works great with FLARM and PowerFLARM devices.  The SN10 can even send a task declaration to the FLARM or PowerFLARM.  However, the SN10's 12V power output does not provide enough current to power a FLARM or PowerFLARM.  Therefore, we have created 2 new SN10 wiring harnesses for use with FLARM and PowerFLARM units.  You can see details using the links below.

  • SN10b-Pnl-FLARM-Pwr-1 - for connecting a FLARM or PowerFLARM to the SN10.  12V power leads are included on the wiring harness for powering the FLARM unit.
  • SN10b-Pnl-PS5a-FLARM-1 - for connecting a FLARM or PowerFLARM unit to the SN10 and a PDA or PNA.  The 12V power for the FLARM unit is provided by either a Goddard PS5a power converter, or an Oudie power/data cable.

New Software Version 2.38 for ILEC SN-10 - FREE Upgrade
There is a new version of the SN-10 software which is available now - free of charge.All new SN-10 units shipped from Cumulus Soaring, Inc. will include this latest software version.

The software is available here: http://www.nadler.com/sn10/SN10_Resource_Index.html

SN10 Data Transfer Software
The ILEC data transfer software is included with the SN10 upgrade software installation.  It is available here:
http://www.nadler.com/sn10/SN10_Resource_Index.html

USB to Serial Converters
New laptop computers do not offer RS-232 serial ports - which are required for transferring files to and from the SN10.  Computer stores sell USB to Serial adapters which claim to offer a serial port through a standard USB port.  However, I have tested several of them and have found very few that work.  I just found a unit that works great with my Windows 7 64-bit computer. It is from FTDI Chip and is available here: FTDI Chip

David Nadler has compiled a very nice list of devices that have been tested and work well.  You can see his page here: http://www.nadler.com/sn10/SN10_USB_Serial_Notes.html

The excellent soaring film A Fine Week of Soaring features many in flight views of the SN-10 in use in a soaring contest.  You can order it here: A Fine Week of Soaring

SN-10B Upgrades
It is possible to upgrade an SN-10 to an SN-10B.  The SN10B is just like an SN10, but with a new LCD screen: Higher-resolution, higher-contrast, and less reflective. When they're turned off, you couldn't tell them apart except for the label.  The document below describes how to get your SN-10 upgraded to an SN-10B for about $350.  You'll find that the upgrade is worth the money.  The new display looks great!
SN-10B Upgrade.pdf

SN-10 Compatibility with GPS Flight Recorders
The SN-10 does not include an integral GPS.  It does include a flight recorder, but it is not IGC approved for validation of any flights.  The SN-10 will work with just about any flight recorder, but can send task declarations to the Volkslogger, so the combination of VL and SN-10 is quite common.  The SN10 also works great with FLARM and PowerFLARM devices. It can send task declarations (maximum of 8 turnpoints) to the PowerFLARM. The low cost (non-IGC approved) option would be to use a Garmin GPS 16-HVS.

How to Create an SN-10b Waypoint and SUA data file
StrePla now makes it easy to export files which include waypoints and airspace for downloading to the SN10.  Below are the steps I used recently.  Several files are created.  One includes the waypoints only.  Another includes the airspace only.  But the largest file includes both waypoints and airspace - that is the one to use. 

  1. Adjust the view in StrePla to show the area you want to export.
  2. Go to the File menu and select Export / Airspace
  3. Select the desired region using the box and select SN10 as the output format
  4. Save the file into the C:\SN10 directory
  5. Edit the header line of the waypoint file with text similar to that shown below.
    H "Stanton MSC Home Grass Field Rny NS/EW 122.8",Timezone -5:00,Magvar -3,Home "Stanton"

Using a Pocket PC for SN-10 Waypoint Database and Fight Log Transfers
It is possible to send waypoint files to the SN-10 from a Pocket PC.  You can also download flight logs from the SN-10 to the Pocket PC.  That way you don't need to bring a PC to the airport.  A utility called PocketDOS can be used to run the ILEC SN-10 utility on the Pocket PC.  The process is described here: SN10 Transfer with PocketDOS.pdf

For a description of the cables required, please see Data Cables - For Data Transfer Only below.

Note: The procedure above has been tested a few times using an iPAQ 3970.  It worked perfectly with a medium sized flight log.  At least one person has mentioned difficulty getting the procedure to work with his older Pocket PC.  Please let me know if you have any problems getting this to work.  Please also let me know if it works well for you.  You can expect very long delays of several minutes at certain points in the flight log download process.

Data Cables - For Data Transfer Only
Any Pocket PC cable such as the I38C-x that would connect the Pocket PC or cradle to the PS-5a can be connected through an ILEC "PC" cable to the instrument panel connector and through the ILEC "Cockpit Panel Cable" (or a custom cable like the SN10b-Pnl-Vb-1) to the SN-10.  Below is a text overview of the connection.  Do not forget to use the ILEC "PC" cable between the Pocket PC cable and the instrument panel connector because it is wired to put the SN-10 into PC communication mode.

Data Cables - For use in Flight
The SN-10 is delivered with basic cables that can be used to connect to most any GPS - but some soldering is required.  Optional custom cables from Goddard are available for connecting the SN-10 to a variety of GPS and GPS flight recorder units.  These cables greatly simplify installation and they are very reliable and robust.  All you need to do is screw them together and you are ready to fly - no soldering required.  Please use the handy Cable Selection Guide to find the cables you need.  For connecting the SN-10 to a GPS only (no Pocket PC) look for the SN-10 at the top right corner of the table and then find the desired GPS in the left-hand column. For connecting the SN-10 to a GPS and a Pocket PC, look for the SN-10 and GPS pair in the left-hand column and then look across the top of the table for the desired PDA.  The table recommends cable options for use in flight.  For cables for use in transferring files while on the ground see the paragraph above.  When ordering the SN-10 you have the option to have the ILEC supplied panel cable modified for connection to a Volkslogger, Colibri or Cambridge GPS-NAV, 302 or 302A for $39 (includes labor and shipping to Goddard and back).  Or you can order the option to have a Garmin GPS 16-HVS GPS attached to the ILEC supplied panel cable for $188 (includes $129 for the GPS and a $59 charge for labor, quick-disconnect connectors, and shipping to Goddard and back).

SN10-2

SN10-2 repeater for 2-seat gliders with vario display - New
Sale - The ILEC SN10-2 is still a great product, but they are not selling as well as they used to. I have more in stock than I need. They are new units. The sale price applies only to units in my stock. This is $800 off the normal price.

This "repeater" display offers the same controls found on the master SN-10.  This unit does not operate independently from the master - the same data is displayed on both units at all times.  That is useful when training others on how to use the system and when you want to show the other pilot some data on their display.

SN10-USB-Adapter SN-10 USB Adapter

PC no longer required at the gliderport!!!
Transferring data from a PC to an SN10 has been awkward in the past.  Most new PCs don't have a serial port, so a USB to serial adapter is required, but only specific USB to serial adapters seem to work with the SN10.  Also, file transfer software must be downloaded and installed on the PC. And PCs have never been easy to use near a glider, or read in bright sunlight. 

The great news is that the new SN10 USB Adapter eliminates all those problems.  After you have installed the SN10 USB Adapter in your glider you can use a standard USB Flash Drive to transfer data to and from the SN10.  It can be used to upload waypoint and airspace files to the SN10, download flight logs from the SN10, and even update the firmware in the SN10.  Therefore there is no longer any need to bring a laptop computer to the gliderport.  Just plug the USB Flash Drive into the new panel-mounted SN10 USB Adapter and use the control knobs on the SN10 to transfer the desired data. 

The SN10 USB adapter attaches to the panel connector on the SN10 Panel Cable.  The SN10 USB Adapter then connects to the instrument panel in the same location that the panel connector from the SN10 Panel Cable had been.  The panel connector still includes a DB-9 connector for connection to an SN10 remote or PC, but it also includes a USB connector. 

The SN10 USB Adapter is a little wider than the panel connector, so some panel modifications may be necessary.

 - USB Flash Drive not included - You can buy a USB Flash drive at Radio Shack, Best Buy, Target, Walgreens, etc. They are not expensive.  You don't need to buy one with much memory.  A 16 MB USB Flash Drive would be plenty for use with the SN10, but it would be tough to find one with that little memory.  Any memory size will do.

The SN10 USB Adapter kit includes the parts necessary to modify the panel connector on the SN10 Panel Cable for connection to the SN10 USB Adapter.  The photo below shows the modification.  Click on the photo to view a larger version.

TE-Fuselage-6mm

Total Energy Probe, Fuselage Mount, 6mm
Total energy probe to be mounted to the fuselage pointing up.  This TE probe mounting method is not as accurate as mounting the probe on the vertical stabilizer. 

Diameter of base that fits into the mount: 6 mm
Diameter of collar near base: 10 mm
Diameter of probe: 6 mm
Length: 330 mm (13")
Length of part that fits into 6 mm hole: 28 mm (1.10")
The single o-ring is located in a slot from about 3 to 5 mm from the end of the probe.

ILEC recommends mounting the probe at least 1 m behind the trailing edge of the wing on the top of the fuselage.

These are the very famous ILEC TE probes. Due to the special design of these probes, they offer excellent compensation combined with high insensitivity to sideslip. This feature of the TE-probe is especially important during thermalling, where a small sideslip is nearly unavoidable. The use of TE-Probes for total energy compensation is superior to the usage of membrane systems or electronically compensation, because the latter two methods strongly depend on the accurate measurement of the static pressure. Static measurement is in nearly all aircraft a serious (unsolved) problem, especially in case of sideslip.

ILEC Probes are made out of a very durable aluminum alloy with a golden galvanized surface to protect against corrosion. Due to the low weight, the tendency of our probe to oscillate is less compared to brass or steel probes. Each probe consists of three parts: the sensing head with its two holes, the tube and the mount with O-ring sealing. The probe is simply installed by pushing it into the opening. The O-ring seals, putting tape around the mount is not necessary. After landing, the probe is pulled out and stored at a safe place.

Maintenance of the Probe
It is recomended to grease the connector slightly, e.g. with Vaseline© Before insertion of the probe make sure the edge of the assembly adaptor is rounded. Otherwise the O-ring easily can be cut and destroyed.

Assembly Note
"For easier transport, extended probes are sent in two parts, and must be assembled by the customer, by bonding.  Put a thin coat of epoxy adhesive (araldite or equivalent), or cyanoacrylate on the end of the this tube.  Mate it with the extender tube, and push them together.  Wait for curing.  Ready.  Attention, do not clog the tube by using too much adhesive.  Bonding surfaces must be clean.  In necessary, clean with organic solvent (Tetra, Tri, or equivalent).  WARNING! Experience shows that with tubes which have not been bonded, the front tube will come loose mostly during takeoff under the influence of shocks to the tail.  Consequently it will be lost here, or during the flight.  This is not only regrettable but may be dangerous.  Where - for any reason whatsoever - the tubes are not being bonded, a wide and tough adhesive tape must be wound around the joint, as a minimum, for safety."

Assembly Instructions for Long ILEC TE Probes
Total Energy Compensation In Practice - Brozel

Note from Cumulus Soaring
The use of tape as a back-up is a good idea if the glue bond is not good for safety purposes of course, but the use of tape alone will probably not provide an adequate seal for good performance of the TE probe.  Small leaks are a big problem with TE systems.
