Being 1/400, it was designed to be printed only in frosted detail plastic. Some parts are exaggerated big so they are stronger. You have to paint (airbrush is best) for the best results. You can use a dark paint wash to bring out the finer details. It is designed to be pulled by one of my 1/400 airport tractors.
This model was designed as 1/400 but you have the option to print it in bigger scales (please request other scales if you need). This is highly detailed so can only print in the detail plastics.
