It comes with four shaft adapters—6mm, 1\/4\", 7mm, and 5\/16\"—so you can fit it on common motor shafts without extra parts. A nylon insert lock nut design keeps the spinner securely attached to the back plate, reducing the chance of loosening during flight. This spinner is intended for hobbyists aged 10 and older who are assembling or upgrading remote-controlled planes.\u003c\/p\u003e\u003ch2\u003eWhat shaft adapters are included?\u003c\/h2\u003e\u003cp\u003eThe spinner package contains four aluminum adapters that let you match the spinner to your motor shaft.

If your shaft is one of these, you can install the spinner right out of the box without buying additional hardware.\u003c\/p\u003e\u003ch2\u003eHow the spinner secures to the back plate\u003c\/h2\u003e\u003cp\u003eUnlike many spinners that rely on a simple screw or friction fit, the Du-Bro 542 uses a nylon insert lock nut. The nut threads onto the back plate and the spinner cone, and the nylon insert creates a tight grip that resists vibration. This design helps keep the spinner from working loose during engine run-up or flight. The entire assembly is simple to install—no special tools are needed beyond a standard wrench or nut driver.\u003c\/p\u003e\u003ch2\u003eProduct dimensions and weight\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpinner diameter\u003c\/td\u003e\n\u003ctd\u003e2 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBlades\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct dimensions (package)\u003c\/td\u003e\n\u003ctd\u003e5.9 x 3.8 x 2.1 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem weight\u003c\/td\u003e\n\u003ctd\u003e0.8 ounces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel number\u003c\/td\u003e\n\u003ctd\u003e542\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eDu-Bro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCustomer rating\u003c\/td\u003e\n\u003ctd\u003e4.5 out of 5 stars (80 ratings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCommon questions about the Du-Bro three-blade spinner\u003c\/h2\u003e\u003ch3\u003eDoes the spinner work with electric motors?\u003c\/h3\u003e\u003cp\u003eThe supplied data does not specify motor type compatibility.
