I've flown in the jumpseat on MD-80s many times. Flying this Maddogg in VR really feels like being in the real thing! The level of detail and systems modeling is outstanding. I only give it three stars because it takes 15-20 minutes to load on my computer. Nearly every other third party plane I've purchased for MSFS loads in 1-2 minutes. This really discourages me from flying it regularly.
I love this scenery, although I have had elevation compatibility issues with the combination of ORBX and Drzewiecki Designs' Seattle Airports X. After many hours of frustrated attempts to work these problems out on my own, I've managed to get issues down to a few elevation issues around the border of the airport, as well as a few houses near the airport floating several feet (40-50ft) above the ground. I have not contacted tech support. The scenery is very accurate for the most part. There are some "colored" taxiway lines (blue and green if I remember coreectly) near the north cargo facility/terminal area (near Spot 55) that are missing. These taxiways facilitate the movement of aircraft around this complex. I fly through KSEA from time to time in my job as a pilot with American Airlines. I really enjoy flying to/from KSEA in real life. This scenery really gives you the sense of being there. If you purchase this scenery and own both ORBX Vector and Drzewiecki Designs' Seattle Airports X, be prepared to contact tech support for help.
