Aluminum Parts
I've had to have a few parts made to ensure glider pilots can get the most out of their gliders.  The machined aluminum parts are made on a machining center and black anodized.  They are very nice.

Cumulus iPAQ Cradles - Sorry - No Longer Available

Overview
Need a way to mount your iPAQ in your glider?  This is the best solution available for iPAQs.  It is simple and light, and it securely holds the iPAQ.  Compatible with iPAQ h3800, h3900, h5100, h5400, and h5500 series Pocket PC's.  The power/data cable exits the back of the cradle so there are no connectors dangling down below the Pocket PC to be knocked loose by your knee.  A 1.0 m (39.4 in) cable is standard with a 9-pin DB-9m connector wired for use with a Cambridge Aero Instruments 302, 302A or Goddard PS-5a Power Converter.  Other cable lengths are available - up to 1.85 m (72.8 in).  The PS-5a power converter can be used to connect the iPAQ to a wide variety of soaring flight instruments.  The cradle's cable contains wires for powering the iPAQ with 5V and data communications with the GPS.  Gooseneck and RAM articulated arms are available.

Retaining Hook
The iPAQ cradle utilizes a simple and reliable retaining hook that locks into a slot on the lower back of the iPAQ.  The hook is held in place by a spring and released by pressing the button on the side of the cradle.  It is very easy to put the iPAQ into the mount, and easy to remove when the button is pressed.

Mounting Tips
The cable is not run through the gooseneck or arm.  The cable is to be attached to the gooseneck or arm using small black tie-wraps.  Since the connector is already attached to the cable, a simple and elegant solution has been devised by Klaus Keim in Germany for passing the cable through the instrument panel.  A small slot is made on the edge of an existing instrument hole, and the cable is put into the slot with the instrument removed.  It makes for a very clean panel.  See the photos below for examples of how this looks.  Alternatively, a small instrument hole filler plate is available - the Gn57mmPlate2.

Gooseneck and Optional Base Plate
The gooseneck and adapter plates are made in the USA.  The gooseneck is very stiff and will hold the mount in position in flight.  It is normally mounted on the instrument panel with washers and a nut behind the panel as shown below.  I don't generally recommend mounting the gooseneck in a location where it will need to bend more than 20 degrees or so because it will eventually become less stiff with repetitive motion. The RAM-GN3-238 adapter plate is used to mount the gooseneck to the back of the cradle.  The gooseneck threads into the optional GnBase2 base plate which is 1 3/16" (30 mm) in diameter and made of aluminum.  The base plate may also be the best solution for thin composite instrument panels.

Gooseneck Vs. RAM Articulated Arm?
I am often asked when an arm should be used, and when a gooseneck should be used.  Both options have advantages.  Both the arms and the goosenecks can be mounted to the panel - extending straight out.  Articulated arms are better for mounting on the canopy rail or cockpit sidewall (bent 90 degrees to face the pilot).  Both options hold the mount securely.  The arms are slightly more stiff than the goosenecks, but I haven't had any complaints that the goosenecks are not stiff enough.  The goosenecks require less mounting space and are more easily adjustable with one hand.  It takes two hands to adjust a RAM arm - one to position the cradle and one to loosen and tighten the nut.  It comes down to personal preference.  I will make both options available and let you decide.  I prefer the gooseneck and I sell more of them than the RAM arms.  Note: Be careful not to mount the cradle where it could interfere with your control stick!

Installation Examples

Installation Examples

Compatible with :: Goddard :: Cable Systems
The iPAQ cradle feature the same DB-9m connections as used in :: Goddard :: I38C-x cables, and connect directly to the Cambridge 302, 302A or GPS-NAV or the Goddard PS-5a Power Converter.  The PS-5a can provide power to your iPAQ and just about any GPS or flight logger.

GNeck2 Flex Arm, 3, 6 or 9 inch
1/8-27 NPSM Threads, The GNeck2 gooseneck flex arm is great for mounting a Pocket PC or GPS in a glider.  Most pilots mount the base of the gooseneck in the instrument panel.  It may be mounted through a hole in the panel with a nut on the back, or it may be mounted to the optional , or in an instrument hole using a Gn57mmPlate2.  The GnBase2 can also be used to connect the other end of the gooseneck to the back of a Cambridge CAA-128 cradle.  The optional  adapter was designed to allow this GNeck2 gooseneck to be mounted to the back of any RAM cradle.  Gooseneck length options are 3 in (7.6 cm), 6 in (15.2 cm) or 9 in (22.9 cm). This gooseneck is much more rugged than the RAP-105-6DD flex arm.  2 nuts and 2 lock washers are included.

Note: Most customers are satisfied with the rigidness of these goosenecks.  However, they are friction devices and the longer length units are less stiff than the short length units.  I now include a steel stiffening rod with the 6" and 9" units which can be inserted into the gooseneck.  I recommend that you try to go without it first and then insert the rod if necessary.  Gooseneck flex arms work best when positioned more or less straight.  They will hold much less load when bent with a sharp angle - such as a right angle bend.

GNeck2-Assy-Thru Flex Arm Assembly, Through Panel Mount
Perfect for mounting and RAM or Seidio cradle to the instrument panel of your sailplane.  The threads of the flex arm go through a 10 mm hole in the instrument panel and are secured by a lock washer and nut (included) on the back of the instrument panel.  This option works well with rigid panels such as those made of aluminum, but I recommend the GNeck2-Assy-Panel for instrument panels of fiberglass or carbon fiber because it offers a more rigid solution. Available in 3 in (76 mm), 6 in (152 mm) and 9 in (229 mm) lengths.  The photo at right shows the 6 inch model.

Included

  • RAM-GN3-238 Diamond Shaped Adapter
  • GNeck2 Flex Arm, 3 in (76 mm), 6 in (152 mm) and 9 in (229 mm) lengths

Note: Most customers are satisfied with the rigidness of these goosenecks.  However, they are friction devices and the longer length units are less stiff than the short length units.  I now include a steel stiffening rod with the 6" and 9" units which can be inserted into the gooseneck.  I recommend that you try to go without it first and then insert the rod if necessary.  Gooseneck flex arms work best when positioned more or less straight.  They will hold much less load when bent with a sharp angle - such as a right angle bend.

GNeck2-Assy-Panel Flex Arm Assembly, Instrument Panel Mount
Perfect for mounting and RAM or Seidio cradle to the instrument panel of your sailplane.  I recommend this option over the GNeck2-Assy-Thru because it offers a more rigid system which is especially important when mounting to fiberglass or carbon fiber instrument panels.  Available in 3 in (76 mm), 6 in (152 mm) and 9 in (229 mm) lengths.  The photo at right shows the 6 inch model.

Included

  • RAM-GN3-238 Diamond Shaped Adapter

GNeck2-Assy-Side Flex Arm Assembly, Cockpit Side Wall Mount
Perfect for mounting and RAM or Seidio cradle to the cockpit side wall of your sailplane.  The right angle adapter allows the flex arm to be mounted parallel to the side wall - just like a boom microphone.  Or it could be mounted to the side of the instrument panel.  Available in 3 in (76 mm), 6 in (152 mm) and 9 in (229 mm) lengths.  The photo at right shows the 6 inch model.

GnBase2 Gooseneck Base, Round
This aluminum base plate was designed for mounting the GNeck2 gooseneck to the instrument panel.  It is 1 3/16" (30 mm) in diameter.  It can also be used to connect the other end of the gooseneck to the back of a Cambridge CAA-128 cradle. The mounting holes are also aligned for use with a Cambridge CAA-127 instrument hole mounting plate.  It is nice for use on thin instrument panels where mounting the gooseneck through a hole in the panel is not ideal.  Mounting screws are included. Made of machined and black anodized aluminum.  The screw holes are threaded so no nuts are required.  Weight: 0.4 oz (11 g)
