Features:
Wonderfully Detailed Model: Our 5-Cylinder Radial engine model kits feature genuine precision-cast and machined parts in anodized aluminum and stainless steel.  Each piece is accurate, detailed and directly correlates to assemblies found in modern, high-performance automobile engines. This is a superb introduction into engineering and mechanics.  
Complete Accessories: The kit contains over 230 parts.  Each finely-crafted part is labeled, and packaged in custom foam carriers to ensure they are organized, complete, and undamaged.  A clear, full-color instruction manual is included.  While the engine is complex, step-by-step instructions – along with some patience – ensure excellent results.  
Simulation Model: A real electric motor inside the starter motor housing drives the 5-Cylinder Radial engine.  The crankshaft, rods and pistons can be observed through special viewing windows.  You can observe the operation of the 5-Cylinder Radial engine during the whole process. It is not only a beautiful decoration, but also a simulation dynamic model that can simulate the operation of a real 5-Cylinder Radial engine. Even when not in motion, it is an impressive machine to see.
Excellent Learning Activity: This kit is not recommended for unsupervised children under the age of 14, due to its small parts.  However, it provides a great opportunity for adults to spend time with children. The child will learn to understand and follow illustrated instructions, manipulate parts and basic tools, and to know the accomplishment of a job well-done.  It fosters an appreciation for the ingenuity in today’s technology as well as the need for it in coming generations.  
Gifts: The 5-Cylinder Radial engine kit is packaged in a colorful, durable metal gift box.  That ensures that the kit arrives intact.  Plus, it makes an excellent presentation when given as a gift.  It is a great idea for anyone interested in mechanical things.
