FiveCylinder Radial Engine Model Kit DM116 Color: 1/6 Scale: 1/6 Overview This detailed metal model recreates a classic fivecylinder aircraft radial engine at 1/6 scale. Designed for hobbyists, collectors, and learners, the kit assembles into a functional, motordriven replica where pistons and crankshaft move in realistic sequence. The DM116 uses precision aluminum alloy and stainless steel parts for a durable, authentic feel. Key benefits Authentic mechanical motion: Motordriven pistons and crankshaft simulate real radial engine operation for a convincing desktop display and handson learning. quality materials: Aluminum alloy and stainless steel construction gives lasting durability and an accurate metal finish. Educational value: Assembly and operation illustrate mechanical principles such as timing, reciprocating motion, and simple drivetrain linkage, making it a strong STEM learning aid. Portable power and safety: Builtin 3.7V 450mAh lithium battery with USB DC 5V charging; automatic poweroff protects the mechanism if external resistance is encountered. presentation: Delivered in a end metal gift box, ready for display or gifting. What makes it stand out Over 250 precision metal components for a realistic build experience. Functional simulation instead of static display, combining a mechanical model with electric drive. Thoughtful safety feature that stops the motor on obstruction to prevent damage during operation or testing.
