Cobra Parts - Bolt-On Prop Adapter - 28mm Extra Long 4-Hole
The bolt-on style prop adapters that come with the Cobra motors are machined from very durable aluminum stock, so they will last quite a long time. However, every so often on a "Not so Perfect" landing you may bend one. For those cases we offer these replacement prop adapters.
The Cobra C-28mm Bolt-On Prop Adapter, Extra-Long (4-Hole) is designed to fit all of the Cobra 2808, 2814, 2820 and 2826 size motors. Included with each prop adapter is a prop washer and nut, along with 4 new screws to mount the prop adapter to your motor.
The Extra-Long Prop Adapter is designed to be used in applications where you are using a prop with a thicker than normal hub along with a plastic spinner with a thick backplate. In these unique applications, the stock prop adapter is just not long enough.
The prop adapter has a metric M6x1.0mm thread, and has a threaded shaft which is 33mm in length, 9.5mm longer than the stock prop adapter. With the included prop washer and nut, this prop adapter will fit props with hub thicknesses ranging from 5mm to 25.5mm or from 3/16 inch to 1 inch.
