737 MTU PMDG/Mobiflight/MSFS Programming

This page is split into three main sections:

Parts Guide

Print Guide

Build Guide

The ultimate printer I can recommend is the Bamboo Labs X1 carbon with AMS if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. Its pretty much press print and go as the software and hardware do the calibration before each print. This printer will not manage the larger parts and you are going to need the CREALITY CR10 v3, which is my second choice of printer.

Welcome to this guide. I wanted to build the MTUv5 as realistic as possible. Unfortunately, prosim is required. After many hours I finally managed to get to a descent system. It isn’t perfect but it is always a fight between realism and complexity. I hope you can get your MTU working just like mine! I divided this guide in steps going system by system (engines, parking brake, …). 1 Arduino mega is used for the whole MTU. So, in each wiring diagram the Arduino mega and power supply is always the same. After that signals go to Arduino nanos running code (included in this guide). The Arduino nanos then signal the stepper motor drivers. I recommend going step by step and testing in msfs before going to the next step. Make sure to watch each element of the links provided closely because sometimes the required changes are a bit hard to spot.
