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 come with the latest BL-Heli firmware installed, and are able to accept refresh rates of up to 600 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. If the user wishes to upgrade the firmware, make changes, or switch to the new One-Shot firmware, this can be done with the optional USB ESC Programmer, which is available separately. This ESC uses the BB21 MCU, so make sure that the correct firmware is installed when changes are made.

The Cobra CP-20A Speed Controller does 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 CP-20A Multirotor ESC comes with pre-tinned 18 AWG battery input leads, which are 95mm (3.75 inches) long, but can be cut as needed for installation purposes. This ESC features pre-tinned output pads, so the motor leads can be soldered directly to the ESC if desired. Also included with the ESC are a set of three 18 AWG motor output leads which are 95mm (3.75 inches) in length. These can be soldered to the ESC if you need to reach further to get to the motors. The total weight of the CP-20A ESC, including the battery input leads and the control lead is 5.8 grams. The set of 3 output lead wires weighs 2.2 grams
