Black Widow 3508-680Kv With Built-In ESC CW/CCW

Do you want deadly performance for your multirotor?  The Black Widow Series of motors have been specifically designed for multi-rotor racing when only the best will do.

More compact, lighter and with greater efficiency, Black Widow motors are premium motor systems incorporating both the motor and ESC into a single unit.   This saves space, reduces overall weight of the model, reduces drag and allows the system to run cooler.

Wth the built in ESC you can also change the direction of rotation of these motors with a simple flick of a switch and there is also a USB compatible flashport at the base of the unit that will allow you to update the firmware. 

These crisp looking units have been manufactured to exacting standards and use original NMB bearings to ensure the smoothest running and reliability of the motor.  Quality mounting accessories are of course included and multiple mounting holes cater for most multi-rotor frames currently on the market.   

If you are into FPV racing and want motors with real bite in performance then its hard to go past the Black Widow Series.
