As the manual is written in spanish, i dunno how to check it with a customed TE yet.
OK - i figure it out.
in TE, all airbases are labeled in RED color! so, tick on the nationa flag on menu bar, select RED/ DPRK, add a flight of ac, save. thne back to TE selecton menu, select this customed TE. to fly red side ac, again tick on the DPRK flag at right upper hand area, the hit commit, enter TE map page, click [fly] and you are in.
terrain looks cool, it's SRTM. in RV, the terrain will show more polygon or elevation data as you getting closer, and inevitably some slopes or flat hills will pop up and disappear due to data loading/unloading. when i riding a F-22 at low altitude, speed over 600kt, i noted a slight terrain loading hiccup, then, when i transit from hills to a desert area, it CTDs. probably due to memory leak or overflow or tile/terrain data loading/unloading issue. i also fly over Gibraltar strait in F-22, heheh just tens seconds and i am over Morrco, north africa!
the small map used for 2d occpupation view looks a bit "granular", due to overlying roads and river lines.
