This Quanum 40A Multi-Copter Brushless Speed Controller is exactly what you are looking for in a lightweight, super-powerful speed controller. The first  ESC with Synchronous Rectification hardware design in the market. This Quanum 40A Multi-Copter Brushless Speed Controller Programmable ESC with 5V/3A BEC. The ESC power input uses extremely low output resistance greatly enhances the power stability and has a protective effect on the battery. Separately voltage regulator IC for the microprocessor. providing good anti-jamming capability. Using Simon K’s dedicated multi-copter program tgy_debug, and the master chip with high stability crystal oscillator, making the motor control more precise. If you are wondering to build a drone and don’t know what will be the best ESC for you then worry no more, we have got your back. At Robu, we have everything for you to get started with your drone project.

Specifications :

Features :

• Drive tube and high-power Mos, and Mos tube plus a separate heat sink, Extreme low output resistance of the PCB(printed circuit board), super current endurance.
• The power input uses extremely low output resistance greatly enhancing the power stability and having a protective effect on the battery.
• Safety electrical function: when the power is turned on, regardless of the throttle stick in any position does not start the motor immediately, to avoid personal injury.
• Separately voltage regulator IC for the microprocessor. providing good anti-jamming capability.
