STEP:

Use the following WD to connect the EFIS:

STEP:

The control panel features seven function buttons—WXR, STA, WPT, ARPT, DATA, POS, and TERR—each accompanied by backlit labels. This backlighting serves to enhance visibility in low-light conditions and applies to both the button functions and the panel text.

However, it's important to note that pressing a button does not cause it to illuminate further or change appearance to indicate that the option has been selected. The illumination is purely static and does not reflect an active status.

Resin Shaft and Knob Upgrade 02/05/2025
Please download the files using the link button. After rebuilding the EFIS for the FSWEEKEND Expo, I made some adjustments that made a huge difference. This mod locates and lock the knobs onto the shaped shafts preventing slip. This MOD should be used for filament printing or resin printing. I highly suggest resin printing these parts as they are much stronger and because of the smooth shafts, require no sanding of the filament parts to prevent interference. All these modded parts can now be purchased in the shop for ease.

STEP:

Insert the EC11 encoder into the Baseplate and secure it with the supplied locknut

STEP:

Insert the 12-position rotary switch into the baseplate and secure it with the supplied lock nut. Ensure the locating tang on the device is situated in the orifice of the baseplate.

STEP:

Insert the 12-position rotary switch into the baseplate and secure it with the supplied lock nut. Ensure the locating tang on the device is situated in the orifice of the baseplate.

STEP:

STEFANS MOD Insert the 6-position rotary switch into the baseplate and secure it with the supplied lock nut. Ensure the locating tang on the device is situated in the orifice of the baseplate.
This D-Shaft rotary switch has no internal stops, so the switch would continually rotate through 360°. A modified gear must be printed to limit the rotation to 60 degrees.

STEP:

Place glue on the 12mm tactile switch's back, then place it into position. Ensure the legs go through the orifices to enable wiring connection. Also, ensure the two legs that hang over the ledge do not short againt the rotary switch lock nut.

STEP:

Place the Spur gear (3) over the rotary shaft. Ensure when the gear is turned, it rotates the switch. If the gear slips on the shaft, you can reduce the diameter offset in fusion with the supplied CAD or calibrate your printer.

STEP:

Place the female spline (5) onto the encoder

STEP:

Place the STD shaft (4) over the female spline (5). Ensure the Std shaft is free to rotate without the interference of the female shaft.

STEP:

Place the spur gear small (7) onto the remaining rotary switch shaft.

STEP:

Cut a section of 3mm bar to 61mm (STOP! 61 is looking short) in length. Gently taper the ends to help fitment. Create Qty 2.

STEP:

Once your test build is complete and the dimensions are confirmed, glue the metal rod into the shaft adapter (2). Karl has created resin-printed adapters that are a better fit and more robust than filament-printed adapters. These are available on the webshop.

STEP:

Place the assembly onto the 12mm tactile switch shaft. It should click into place. Be gentle!

STEP:

Place the spur gear shaft (6) over the metal rod and engage the teeth of the rotary gear. Ensure there is no binding between the adapter shaft and spur gear shaft.

STEP:

Place the encoder into the other backplate and secure it with the supplied lock nut. Ensure the locating tang is correctly situated in the baseplate orifice.

STEP:

Add Qty 2, 12 position rotary switches. Secure with locknuts and once again make sure locating tangs are situated correctly in the baseplate.

STEP:

Place glue onto the back of the 12mm tactile switch and place it into position.

STEP:

Place the spur gear (3) onto the rotary shaft. Ensure the gears rotate the switch.

STEP:

Place the female spline (3) onto the encoder shaft.

STEP:

Place the STD shaft (4) over the female spline (3)

STEP:

Place the small spur gear (7) onto the rotary switch shaft

STEP:

Place the shaft adapter assembly and rod onto the 12mm tactile switch shaft.

STEP:

Place the long spur gear shaft (6) over the rod assembly.

STEP:

Place the backplate assemblies into the centre case (9)

STEP:

Insert Qty 6, M4 x 10mm screws to secure the backplates.

STEP:

Place the collars over the lower shafts. Pull the shafts forward and the collars fully against the centre case. Tighten the grub screws to secure the collars. Ensure all shafts are free to rotate and all four centre shafts can be pressed to operate the button switches. If not, investigate the cause and correct before proceeding.

STEP:

Insert the centre assembly into the outer case (12B)

STEP:

Insert QTY 2, M4 x 8mm Countersunk screws.

STEP:

Turn the unit 180 degrees. Insert a further QTY 2, M4 x 8mm Countersunk screws.

STEP:

Place the QTY 2 toggle switches into the front body (12A). Secure them with the supplied locknuts.

STEP:

Insert QTY 12, 12mm LED tactile switches into the front body (12A). Bend the legs over (outwards)to help secure them. Ensure the LED anodes all face the same way!

STEP:

Use a length of 12mm warm white LED strip around the edge of the front body 12B.

STEP:

Place the front body 12A on the primary assembly.

STEP:

Place the back plate (11) over the shafts onto the main assembly.

STEP:

Place the 7 square buttons onto the unit's lower orifices. Then place the QTY 2 round buttons on the top two points.

STEP:

Place the faceplate onto the unit and secure it with QTY 4, M4 x 25MM screws.

STEP:

Place the backplate onto the unit and secure it with QTY 4, M4 x 8mm screws.

STEP:

Place the knobs onto the relevant shaft and secure them with Grub screws.

STEP:

Place the CTR and TFC button caps onto their shafts. Glue if they are not a tight press fit.
