Model building is a fun pastime for the whole family, allowing you to create detailed scale replicas of the world's most famous aircraft, ships vehicles and spacecraft, both fact and fiction! All Revell plastic model kits are arranged into a 157-tier 'Skill Level' system, which lets you see the most appropriate level for you or the person you're purchasing for. From this, you can choose kits from the most appropriate level or levels, dependent on previous building experience.
