FiveCylinder Radial Engine Model DM116 1:6 Runable Mini Engine Kit Bring a piece of aviation mechanics to your workspace with this realistic 1:6 scale fivecylinder radial engine kit. Precisely machined metal parts, a functional electric drive, and a handson assembly process make this kit suitable for hobbyists, modelers, and anyone interested in the mechanics of aircraft engines. Key benefits Real operating simulation: Assembles into a runable radial engine that demonstrates real motion and linkage, giving a clear, handson understanding of how radial engines work. Durable metal construction: Major components are made from aluminum alloy and stainless steel for realistic weight, texture, and longevity. Compact display size: Finished model measures 19.9 x 19.9 x 11.4 cm and weighs 1900 g, making it suitable for desktop display or demonstration. Safe, convenient power: Builtin lithium battery 3.7 V 800 mAh with DC 5 V USB charging. Charging time about 2 hours. The unit includes automatic power off when encountering external resistance to protect the mechanism. Educational assembly experience: Over 250 parts provide an immersive build that teaches mechanical assembly, patience, and problem solving. Assembly difficulty rated 4 stars with an estimated build time of about 4 hours. Complete kit and packaging: Supplied in a end metal gift box with engine set, installation tool set, and a paper English instruction manual.
