Description
INDCM-4510-28 Cobra CM-4510/28 Brushless Multirotor Motor
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 CM-4510 series motors have a 6.0mm 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 CM-4510 motors come without bullet connectors and feature extended pre-tinned motor leads that are 13 inches (330mm) long. These motors also have 3mm threaded holes in a 25x25mm pattern on the back plate for easy installation on your model.
The CM-4510 series motors allow for multiple propeller mounting options. They have a pair of 3mm threaded holes that are 12mm apart for mounting carbon fiber props that use this attachment method. There are also four other 3mm threaded holes for attaching the included bolt-on style prop adapter. This prop adapter has an M6x1.0mm thread for holding traditional multirotor props that have a 6mm 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.

Four M3x6mm Motor Mount Screws
