first of all...  this is a b767..i cant see how a b757 can be similar to a b767...just only in the cockpit and some panels...

- this one has a nice,real and hq model..very friendly on the FPS and has a lot of details and animations
the front panels are the same.but this one has diferent overhead panel as a real b767 and diferent color,gauges,ect  
a real nice virtual cockpit and a lot of animations....
see the pictures and make your own test
- a super stable..real and nice aerodinamics...you can fly the plane just using the trim...
you can perform a really nice landing thanks to this air file or aerodinamics..very real...thanks CS
very friendly with the FPS in model,panel.virtual cockpit and animations.

FOR ME : this one is the BEST 767 in the fs market now

the bad things

- the overhead panel still off while the engines are running..exept if you start the plane in cold and dark mode...

try this bird and you can change your life inside FSX... ;D
