LX (9070) Sim Gliding Navigation Computer

I designed this model for my Microsoft Flight Simulator cockpit. I primarily use it with the Got Friends AS33 MSFS sim glider, but it should work with any other glider or simulator that allows undocking the LXN instrument via HDMI and supports Mobiflight. This includes all MSFS gliders equipped with navigation computers from the LX family that are based on the B21 Gliding avionics work.

Included are the Mobiflight and Arduino configuration files with the mapping for the GotFriends AS33 (15/18 m). All functions can be reassigned to any other simulator variable or aircraft supported by Mobiflight.

Mapping and functions are based on the GotFriends AS33 manual: https://www.got-friends.com/collections/payware/products/as-33-me

Print Settings

• Material: PETG/PLA

• Layer height: 0.2 mm

• Supports: None required

• Notes: Increasing perimeters to 3 improves rigidity; 2 perimeters also works.

Assembly Notes

Basic soldering skills and general electronics knowledge are required.
Different Mount options with M4 holes are available for desk or panel mount.

Connect an Arduino GND pin via wire to any pin of each button and to the center pin of each encoder and wire the signals corresponding to this:
(If you don't match the correct L/R or buttons signals at the encoder you can fix it later in the mobiflight mapping)

Software

Download and run Mobiflight Software and connect the Arduino to your PC. Firmware will be automatically upload to the Arduino.
Upload the includes Arduino config MobiFlightUnoLXN.mfmc in the modules section.
Load the LXN.mcc mapping. Run the Sim and run Mobiflight.
Help for other configs and mappings you will find at https://www.mobiflight.com
