Cobra Parts - Bolt-On Prop Adapter - 28mm 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 (4-Hole) is designed to fit all of the Cobra 2808, 2814, 2820 and 2826 size motors. This is the same model that comes packaged with a new motor. Included with each prop adapter is a prop washer and nut, along with 3 new screws to mount the prop adapter to your motor.
The prop adapter has a metric M6x1.0mm thread, and has a threaded shaft which is 23.5mm in length. With the included prop washer and nut, this prop adapter will fit props with hub thicknesses ranging from 5mm to 16.5mm or from 3/16 inch to 5/8 inch.
