If so, you need to go into the material room and reverse nomals on all of the different wing sections.

 

There is this wing package too. I haven't used it.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
