Cobra Parts - Bolt-On Prop Adapter - 2221 Series 4-Hole
ThThe 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-22mm Bolt-On Prop Adapter (4-Hole) is designed to fit all of the newer style Cobra 2221 size motors that have 8 cooling holes on the front end. 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 4 new screws to mount the prop adapter to your motor.
The prop adapter has a metric M5x0.8mm thread, and has a threaded shaft which is 18.5mm in length. With the included prop washer and nut, this prop adapter will fit props with hub thicknesses ranging from 3mm to 12.5mm or from 1/8 inch to 1/2 inch.
