Marc got a lot of feedback on his original Bengal/Ranger hybrid, so he decided to implement a bunch of the suggestions. The changes to the design are fairly minor such as adding a texture to the sides of the flight deck but it all adds to the overall effect.
I pretty mutch agreed with most of the comments and followed their suggestions, minor stuff really.here.
The one thing I didn't really agree with was Edfilho's suggestion of putting wings on it. BUT I'm always willing to consider the other side of things... so I tried it and something strange happened :)
