Cobra Brushless Motors offer performance and value for Sport Flyers and Competition pilots alike. They are built from high quality components, and are designed to give years of top-level performance. All Cobra Motors are shipped in a custom designed package that features protective foam on all sides, with separate compartments to protect the motor and accessory pack.
The Cobra 2203 series motors have a 3.0mm shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. The stators are made with 0.20mm laminations for maximum efficiency and minimum Eddy Current losses. Since these motors are typically soldered directly to the speed controller to save weight, the 2203 motors come without bullet connectors and feature pre-tinned motor leads. These motors also have a cross mount built right into the back plate for easy installation on your model.
Included with every Cobra 2203 Series Motor is a complete accessory package which contains the following items:
● Four M2x8mm Motor Mount Screws
● O-ring prop adapter with 2 screws
● 20mm dia. x 2mm O-Ring
The O-Ring prop adapter is a reversible unit with a 5.5mm centering ring on one side to fit GWS Slow-Fly props, and a 7.0mm centering ring on the other side to fit GWS DD series props. With the proper center hole adapter ring, GWS Slow-Fly props and other brands will also fit perfectly on the prop adapter.
