Why do 737DIYSIM plans differ from the real Boeing 737?

If you have visited my website before, you probably realise I am on a very limited budget. Most of people I speak to and visit are also on a very small budget. My plans have been adjusted from the real aircraft, not only to make things simpler if possible, but to allow cheaper alternatives to be used. They are not millimeter perfect! For that I would need an actual 737.


However, despite there being the odd measurement that is off by a few millimeters, there are now two intentional design changes that I made for cost purposes and to allow others the same benefit. These are not mistakes, despite them be pointed out to me and other builders of my plans.


These difference are all based around the monitors. The MIP base was changed to accommodate various screen size, so your not limited by just one screen size, below is how the design was changed in the MIP:

The next major change which gets highlighted is the FMC Console, Once again this design change was carried out to allow multiple sizes of monitors to be used instead of the very costly 10" monitor:


Why 737DIYSIM FMC Console differs from the real aircraft

I designed these plans over several years. They are as close as I can make them without asking Boeing to supply me the actual aircraft plans/blueprints direct. What I can promise is that its now a proven design. This means when you build one part, it's going to fit perfectly with the next part.


The whole cockpit is now fully built in Fusion 360 and just require finessing as I build the parts. With the help of other builders who follow along and highlight things they don't understand or I have missed. These plans will only get better as time goes on.


I hope this helps you understand why this was done and I personally do not think it makes the sim look any less real. If you have followed along and built from these plans, give yourself a massive pat on the back! It's a massive achievement and I hope its gives the excitement and thrill it does for me. But let me state, if your after perfection and 100% realism, this site and plans may not be for you.
