Compact, reliable, and easy to install, it became a standard feature on many British aircraft during the First World War.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOur scale replica comes in full color and is easily assembled!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWant the propeller to spin in the wind?
