Hello Dunai,

you mentioned "You have to turn terrain layer off to make it fly on my system."

did the model jump around irratically while playing the views?
if so, you may want to redownload, i had to change some of the view settings.


wing section moved off of diagram in this image for visual.



I used strictly SketchUp to create this model

if i use another app to create a model i credit the app within my post.



thanks for the reply
