This YF-16A was the second F-16 built and was used to evaluate the characteristics of the new type. One of the important factors of the evaluation of a combat machine is in the determining of a proper color scheme to help conceal the plane from the eyes of the enemy pilots. The markings on this model of the YF-16A represent one of the interesting color patterns used to determine the effectiveness of the camouflage. Eventually a scheme of all gray shades was adopted, but it is interesting to note that the latest French camouflage schemes for their new fighters is almost identical to this scheme. Models are supplied unpainted and some assembly may be required.
