Finally, I give up continuing to improve this model, so, I decided to publish this version.
Reason? why? for something made me sad very very much....
Operation
Press F6 to change to the camera to view your plane from this simulator on the earth surface, just like to fly an RC plane
Press F7 to change to the simulator view, view the simulator cockpit flight instrument, view the displays matrix forward of your simulator cockpit, fly as normal, but, without the sounds of your plane
all the other operations the same as the original plane.

I have changed my picture bed, I have used DeviantArt ago, but DA website always encounters all kinds of bugs, now I use QQ zone, but players outside China may be not able to load the images quickly.
