Instruction Manual
1. Introduction
This manual provides detailed instructions for the assembly, operation, and care of your COBI Northrop F-5A Freedom Fighter Aircraft model. This set allows you to construct a detailed 1:48 scale replica of the iconic F-5A Freedom Fighter, as used by the Royal Norwegian Air Force (Luftforsvaret).
The F-5A Freedom Fighter was a light fighter aircraft developed by the American Northrop Corporation, introduced into service in 1964. Known for its maneuverability, operational simplicity, and relatively low cost, it became a popular export model globally. The aircraft played a significant role in various conflicts and served as a pilot training platform. Norway acquired 108 F-5 aircraft between 1966 and 1972, utilizing them for nearly 35 years before their withdrawal from active service in 2000.
