1/700 WWII IJA Type 98 20mm AA Gun

Kits that we have rated as skill level 4 require all the same modeling techniques and tools as skill level 3. However, these kits tend to include more and smaller parts, the use of multiple materials (resin, white metal, photo-etched, etc.) to complete the kit, and the need to perform some modifications to the parts before they can be used, such as changing their size, opening holes, etc. To properly complete a level 4 kit, you will want to have all of the skill level 3 tools. In addition, a pin-vise (hand-powered drill) and plastic saw will assist in modification of parts when necessary.

Kits in this class are not suitable for small children at all. Children under 14, even if experienced, are likely to have difficulty with a kit like this if they attempt it alone. Adults who have never before completed a plastic model kit are advised to avoid kits of skill level 4 or 5 until they have gained modeling experience working with something less challenging. Examples of kits in skill level 4 would be injection-plastic kits of cars or aircraft that include resin or white metal modification parts, or kits that call for you to cut or otherwise modify existing parts in some way. Many resin figure kits with many parts would also fall into this class.
