Q: ESC—Is one as good as the next?
A: Does a Gremlin handle like a Mercedes?
Many overlook the importance of the ESC. But if you prefer your motors to run with the smoothness, power and precision of a Mercedes, then you’d be wise to consider the superior qualities that catapult the 
ESC above the rest of the field.
- SUPERIOR PROGRAMMING – The team of programmers spent 3 years perfecting their “smooth start” ESC. Utilizing the already high level SimonK firmware, Emax made improvement after improvement until they had created the best high performance speed controller available.
- HIGHEST QUALITY COMPONENTS – ESCs come with an American made (IR) MOSFET for a very stable current that leads to a long life. In addition, the PCB is made from thick 5-oz. high grade copper, helping to further increase the ESC longevity. Other components such as the capacitor and resistor also follow in the Emax tradition of exceptional quality.
The moral of the story: All ESCs are NOT alike.
If you trust your ESC to just anyone, you may find your multicopter crashing to the ground like a meteorite.
