Thanks. Much has been done on the onboard side of this project. Soon i will have to concentrate on the Ground Control part of it which is the challenge for me. I need to gather a good understanding of the internals of FlightGear and improve my programming skills in C++. I just know that it is logically possible to do what i have in mind and set forth to do it.

How well does this work considering that real world weather conditions are very different from those in the simulator? Control surface responses are never similar?

Looking at others work can spark new ideas and put them into perspective... -- Cheers!
