1/72 Wright Cyclone R3350 engines (4 pcs)

Kits that we have rated as skill level 5 require all the same modeling techniques and tools as skill level 3 and skill level 4. In addition, skill level 5 kits are often composed entirely of materials other than injection plastic, can contain many very small parts, often require extensive modification of parts to complete, and in some cases do not come with English-language instructions (Japanese only). Kits of this latter type require a degree of engineering common sense on the part of the modeler, as well as extensive test-fitting, to properly assemble.

Tools and supplies required to complete kits of this class are unchanged from those of skill level 4. 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, and even this may not help. Adults who have never before completed a 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 this class would include resin and metal kits of racing cars and ships, accessory parts for such kits, and advanced, posable resin kits of science-fiction items.
