This piece comes from an extension collection and is in very nice cosmetic condition. The crankshaft DOES Seem to turn, though not entirely.
It likely needs some sort of service. My guess, judging from the collection from which this came, is it probably needs light work, but I cannot guarantee that. This item is in the category "Toys & Hobbies\Radio Control & Control Line\Control Line & Free Flight". The seller is "jastermereel" and is located in this country: US. This item can be shipped to United States.
