Along with the development of model aircraft, more and more ESCs have come into the market. How to choose the right ESC for the aircraft has become a problem.

Skylord series ESCs are applicable for airplane and primary helicopter and have a total of 11 models ranging from 6A to 100A in continuous current which could meet nearly all airplanes’ need. ESC is an important step in the process as you need to ensure your ESC can handle all power passing through it. Now here is the evaluation about Skylord series ESCs and something important when user chooses the ESC.

Appearance

Skylord ESCs are small size with simple packing, which are convenient for ship and carry. Every ESC has different continuous current as well as the corresponding size.

In addition, a user manual in Chinese and English is included.

Product features

With great drive capability, the highest motor speed can reach 210000 RPM (2 poles), 70000 RPM (6 poles), 35000 RPM (12 poles).

Support three start modes: Normal, Soft, and Super-soft, It takes 300 milliseconds, 1.5seconds and 3 seconds from initial throttle advance to full throttle in corresponding. Normal mode is suitable for fixed-wing aircraft. Soft and very soft modes are suitable for helicopters.

The ESCs have full protection features such as low voltage protection, over-heat protection, over-load protection, and throttle signal lost protection, it can effectively extend the service life of the ESCs.

Support multiple programmable items which could meet more users’ need.

A 3-in-1 programming card with a very small size and intuitive interface can be purchased additionally for easily programming the ESC. It brings much more convenience for users than transmitter.

Specifications

Here is the table below about ESCs’ specifications. User can choose the appropriate ESC depends on situation.

6A to 30A Skylord ESCs, they are all Linear BEC that reducesthe voltage from the main Lipo to 5V by converting the excess voltage into heat. The advantage of this kind of ESC is its small size and low interference. However,as input voltage gets higher, or current draw gets larger, more power will be wasted and converted into heat. That’s why this type of voltage regulator is not ideal for high input/output voltage difference or high current application.It’s generally only used on 3S or below.

As for 40A~100A, use the switching UBEC when the current application is much higher. In fact, the Switching UBEC are more power efficient and the BEC tends to overheated with large input/output voltage difference, but switching UBEC doesn’t have this problem and thus more reliable. In addition, switching UBEC generally can provide more current safety.

Important Items

Continuous Current: indicate the maximum amount of constant current allowed to pass through to the motor safely. If you draw more current than it can handle, your ESC will start to overheat and eventually burns out or even go up in flames. For example, the Tomcat motor named TC-P-3510-KV1080, whose max burst current is 30A needs the ESC’s continuous current over 30A, so it is better for user to choose the ESC named skylord-40A-UBEC. In addition, the fact is there will be no power gain to your motor when using ESC with too many amps. In fact, using 40A ESC doesn’t mean your airplane is flying faster than using 20A ESC, instead your airplane will be heavier.

Burst Current: might allow a higher current to pass through for a short period of time such as 10 seconds. Over this time, the ESC will bust out.
