Cobra Brushless motors are manufactured with high quality and durable components. All Cobra engines are delivered in a specially designed packaging, which are lined on all sides with foam protection. In this way the motors and accessories are maximally protected.
The Cobra CM-2204 motors have a 3.0mm motor shaft for extra strength, and a large ball bearing shaft. The stators are 0.20 mm thick laminated so they provide maximum efficiency with minimal eddy current loss.
The motors are to save weight, soldered directly to the speed controller.
The Cobra 2204 engines do not require Bullet plug. The motors are 3 mm threaded holes in a 16x19mm pattern on the backplate. This ease of installation is guaranteed.
The latest version of the CM-2204 motors have an integrated 5mm threaded motor shaft which prevents prop adapters spin-off in flight.
The supplied Prop Washer and the nylon insert nut Prop enable stable attachment, which can loosen or slipped nothing.

4x M3x5mm Motor Mount Screws
