I installed your aircraft and the first thing that happened when I started FS9 is it updated the scenery files? What is that all about? Also, there are some files for the gauges directory, did you progam those or are they freeware you picked up somewhere? And what about that Auto Pilot?
Next, what are you talking about when you say it will not go fast. On my confuser it went up to Mach 4.04 at sea level with only a little shaking, and I got Mach 4.65 at FL500 with the aircraft smooth as silk. Other aircraft will have the elevator fludder at those speeds but non on yours. Pulling up on the elevator at Mach 4.+ and it's momentum had me hitting the 100,000 ft barrier in no time. The hardest part of flying this thing was keeping the screen from blacking out with high G's. My own aircraft design starts to become pitch sensitive at FL400.
I like the chrome effect on the engines and leading edges. Do you have a tutorial on how to do that. I can't seem to get that kind of shine on my aircraft.
I found the cockpit windows restrictive and you should add more glass. There are no side windows? Hard to do a visual circuit that way...

Also the engines seem physically small for the size of the aircraft and the power they put out.
So you are leaving me with a lot of questions .... "How did he do that?"
I can see there are a bunch of things to finish off, but over all - Very Cool!!!
