Cobra Brushless Multirotor Motors offer performance and value for Your RC Models. 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 CM2217 series motors have a 3.17mm motor 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 for reliability, and often need to be cut to length for the specific installation, the CM2217 motors come without bullet connectors and feature extended pre-tinned motor leads that are 17 inches (430mm) long. These motors also have 3mm threaded holes in a 16x19mm pattern on the back plate for easy installation on your model.

The CM2217 series motors include a bolt-on style prop adapter has an M5x0.8mm thread for holding traditional multirotor props that have a 5mm center hole. The included prop washer and nylon insert prop nut provides a solid attachment for your propellers that will not loosen up and slip during use.

Included with every Cobra CM2217 Series Motor is a complete accessory package which contains the following items:

● Four M3x6mm Flat Head Motor Mount Screws
● Three M2x6mm Socket Head Prop Adapter Mounting Screws
● Machined Aluminum Bolt-on Style Prop Adapter
● Machined Aluminum Prop Washer
● Locking Prop Nut with Nylon Insert
● Machined Aluminum Cross Mount
