Thought I'd post a log of development of these planes. They are built of the amazing Buckaroo MD-81.
So far I have 4 models. [MD-82, MD-87, MD-88], and [MD-90].
Some cockpit shots currently:

Main panel MD-82, MD-87:

Note: MD-82 is on the full analog panel by default. Switch with MD-82 --> Toggle Retrofit
MD-82 Full Analog Panel (MD-82 --> Toggle Retrofit):

Upgraded EFD MD-90 cockpit has been removed since I can't find enough information to replicate it realistically.
Overhead:

Exterior MD-87 (Thanks Martien Van Der P!):

Liveries coming soon!
Exterior MD-90 (Thanks Martien Van Der P!):

FMSs coming soon.
The motto of these planes is: Everything you see, works (most of the time anyways).
I'll be posting here as I do major things. If anyone wishes to contribute, you are welcome!
