J Perkins RC Aircraft Spinners & Backplates

Find the right spinner for your fixed‑wing model in our Spinners category, part of the Props, Etc range. We stock a wide selection from J Perkins, Fusion, SC, Dubro and Radio Active to suit electric, glow and petrol aircraft. Choose by diameter to match your cowl and prop – common sizes include 30 mm, 40 mm, 51 mm, 57 mm and larger. Pick 2-blade or 3-blade cut-outs to suit your propeller, and decide between lightweight plastic for park flyers and sport models, or precision aluminium for added strength and heat resistance. Backplates are available in plastic or metal, and we carry both collet (for smooth shafts) and bolt-on/adaptor types (for threaded shafts) with a range of shaft sizes. Tips: measure your crankshaft or motor shaft carefully, ensure the backplate hole pattern matches your prop, and check there’s clearance for spinner screws and cooling. Balance the spinner/prop assembly to reduce vibration and protect airframes and bearings. With our large UK stocks, friendly expert team and fast despatch, it’s easy to get exactly what you need — including next day delivery options for UK customers. Not sure which spinner fits?
