If you’re an RC enthusiast and love to fly your planes or quadcopters in the free, open air, then you will be able to understand the value of a quality Electronic Speed Controller like this 40A Bidirectional Brushed ESC without Brake. This ESC is capable of 40A continuous draw, with 340A instantaneous draw in both forward and backward mode, and operates on a variable 7V to 24V DC supply to allow for a wide range of different batteries, with Lithium 2S batteries being the recommended batteries to use.

Bear in mind that this ESC does not have a brake integrated into it, which does offer some great benefits compared to braked ESC’s, but may not be the ideal choice for everyone. However, most of the problems that are commonly associated with non-brake ESC’s can be remedied in a variety of ways, and we prefer to choose brakeless ESC’s whenever possible so as to save on unnecessary costs while still enjoying the same flight quality that we’re used to.

Finally, this ESC also features an onboard heatsink to protect the controller from heat generated by high current draws, with good quality RC Connectors and cabling to ensure that all of the connected components are also kept safe from electrical or thermal damage.
