Cobra Multirotor Speed Controllers are designed to be the perfect compliment to the Cobra Multirotor motors, but can also be used with virtually any brand brushless motor. These speed controllers use a proprietary firmware that is optimized for use in multirotors, and are able to accept refresh rates of up to 500 Hz from your flight controller board. They come set up and ready to go from the factory, so in most cases, no programming of any kind is required.

The Cobra FPV Mini Speed Controllers do not provide BEC voltage to power your receiver or servos. A separate battery or BEC circuit is required when using these speed controllers. In most cases, you can use a power distribution board with a built-in 5 volt switching regulator circuit. The control lead on this ESC only has the Signal and Ground connections, so there is no need to pull the red wire out of the connector..

The Cobra 20A Mini FPV Multirotor ESC comes with pre-tinned input and output leads, which can be cut as needed for installation purposes. The battery leads on the ESC are 18 AWG, and the motor leads are 20 AWG.
