To add to these comments, -200 new version (2.6) feels much better than before. After a few flights the fuel usage is good and I can reach cruising altitude (FL340).

One new bug I noticed is that in the simicons graphic when I open the graphic to control doors, the airstairs button now opens the main door, not the airstairs. 

Other than that I'm very pleased with both the 100 and 200 products.
