These polished aluminium spinners are machined from aluminium bar stock, with a machined back plate. To the rear of the spinner there is a small-machined lip, and the lip locates securely to a similar lip on the edge of the back plate, this ensures the safe location to the back plate time after time.
Each spinner comes with a prop adaptor, reducer ring, and a hex wrench to make fitting to any model easy, and the spinner itself is pre-cut to take two-bladed propellers, so there is no need to struggle with this often awkward job.
Do not confuse these top quality spinners with the spun aluminium type, these spinners really are top quality, durable items that will stand up to the rigours of the occasional nose over without getting dented, of suffer distortion due to centrifugal forces. Available in a range of sizes from 38mm, 1 ½ inch right up to 152mm, 6inch to fit sport or scale models.
