FSX/P3D. At least one project is pushing 7 years in development. Others take about 2 to 3 years. In the case of Alabeo, it's all down to a matter of months between projects and I must say the level of quality that keeps getting delivered in these short time spans are impressive. I absolutely love these small aircraft from these developers but I to look sometimes dream of a future of Carenado/Alabeo, developing aircraft like the BBJ, or Gulfstream or even large commercial airlines with complete systems. This will not likely ever happen. But I can dream... In the mean time, I just can't get enough of their developments. Check out the latest shots of the DA-40!
