I have made some small updates to the existing Robin DR400-dauphin, you need FlightGear 2018.3.1 or newer to use it because it can optionally have a glass display using the FG1000 instrument based on Garmin G1000 that is part of the new FlightGear.

The changes I made where mainly to make it closer to the newer Robin DR401 155CDI because I have been using it a lot in x-plane lately, and also because I wanted to try the new FG1000 after using the canvas ZKV1000 in the past on some of my other updated planes.
Main changes:
-Optional glass cockpit based on the FlightGear instrument FG1000.
By default it starts with the existing classic cockpit and FG1000 is not loaded or initialized for maximum performance, once you toggle it from he menu or by pressing "g" it's loaded and initialized the first time, and if you toggle it again it remains loaded and running in the background even if it's hidden.
The FG1000 is completely vanilla and it's loaded from flightgear's folders so any improvement in the future of the instrument with flightgear will be used automatically.
Compared to the ZKV1000 it has antialiasing issues and I notice some frame rate stutter from time to time when the map is updated but hopefully these issues will be fixed in the future.
The placement is not realistic as the DR401 has a different panel and cockpit compared to DR400.
-New glass effects including reflections and rain effects.
-It's based on the version found on FGMembers with a few improvements I merged from the version on Patten's Hangar and a few extra liveries from the x-plane version from XPFR (they are all GPL), I only chose the liveries that didn't have fake painted windows or errors.
-Sound improvements and bugfixes including new rain and thunder sounds.
-Automixture to make it closer to the new DR401.
-The model of the engine and propeller was changed to be close to the 155CDI version (the appearance is the same), although it's not perfect, since the 3d model doesn't match either, so between 6000 and 10000 ft it's pretty good, bellow that is a bit too strong and above a bit too weak. This can be fixed by adding a boost or even simpler by making the engine stronger and reducing the maximum mixture from the automixture script to something like 0.8 but for now I am happy with the model as it is.
-ALS lights and procedural lights.
I also tried adding shadows but the cubemaps I modified by hand (since I don't use blender) where too bad so I kept it without shadows as it is.
The original plane seems to have wrong Vne (176 instead of 146) and wrong fuel capacity (more than it should), I didn't change these values.
