The Cobra Champion series motors are the most powerful versions ever made for FPV Racing! A completely new design that increases cooling and efficiency, these motors provide the ultimate power for your FPV Racing Quads. 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 CP-1407 motors come without bullet connectors ,and feature extended pre-tinned motor leads that are 3 inches (75mm) long. These motors also have 2mm threaded holes in a 12x12mm pattern on the back plate for easy installation on your model.
The CP-1407 series motors are designed for the Micro size FPV racing quads and feature an integrated 5mm threaded motor shaft which eliminates the chance of having a prop adapter spin off in flight. The included nylon insert prop nut, which has an integrated prop washer, provides a solid attachment for your propellers that will not loosen up and slip during use.
Also included with every Cobra CP-1407 Series Motor is an accessory pack, which includes everything you need to securely mount the motor to your quad frame, and to mount the prop to the motor.
The hardware kit contains the following items:
● Four M2 x 5mm Socket Head Motor Mount Screws
● One 1.3mm Hex Key Wrench
● One Locking Prop Nut with Nylon Insert
*Please observe the motor specifications properly. This will determine the correct size ESC required for proper operation*
