KINGMODEL 1S 4A Brushed ESC
The KINGMODEL 1S 4A brushed ESC is ultra-small speed controller , can drive all kinds of 1S 720, 820, N20, N30 motors. It is a good choice for a 1S small plane and a small boat.
It is a unidirectional brushed ESC.
Suggestions: If you want to fly with FU-TA-BA or FLYSKY receiver, 8520 or even 1020 hollow cups, you can use this ESC. If you use radio-link, you should use it in 2A-3A. As the current is too large and the voltage drop is too large, the radio-link receiver can be disconnected. Please note that the receiver is disconnected due to the large voltage drop. This ESC has nothing with the ESC 2.7V. To do
Parameters
- Voltage 3.6V - 5.8V Current 4A (1S lithium battery or 4 NiMH).
- Remote control signal PWM (1000-2000)) (1100-1900) automatic adaptation of the run.
- Low throttle starts to prevent unsafe safety of high throttle motor rotation.
- With out-of-control protection (lost signal (equivalent to the ESC signal line is broken), the motor stops).
- Receiver power output = battery voltage minus 0.2v or 0.3v maximum allowable current 3A.
- Item Name: Electronic Speed Controller
- Model: Brushed, Voltage: 3.6 - 5.8 V. Current: 4A (support 1S LiPo battery).
- Remote control signal PWM: (1000-2000) (1100-1900) automatic adjustment of the run.
- Size: 18.5 x 9.5 mm, Weight: less than 1g (only plate without wire), Weight: 5g plate with wire 5g.
- Application: suitable for all types of 1S 720. 820 N20 N30 Engines.
Wiring diagram & size
Receiver power supply:
- The power supply mode is that the battery is directly powered and there is a 3A freewheel diode.
- But when a large current is used, the voltage drop of the
- 1S battery is very large. If the battery voltage is 3.88V, the voltage is reduced by 3.06V when the current is 4A. The ESC can work with this voltage, but the receiver does not necessarily work.
- The measured world flies 7-way, and the foot 3-way receiver 3.06 V can still work normally, but Led will not work.
Application: suitable for all types of 1S 720. 820 N20 N30 Engines.

These are very convenient to drive small brushed DC motors (3.7v). They provide 5v BEC for a receiver and servos. Your may have to splice in different connectors depending on what batteries and receivers you use.The price is very competitive.

Work great but limited amps

The stock airplane is alright. Swapped everything for the AR410, 2.1g servos and this ESC. It runs a 1020 coreless motor. No power issues and everything works fine. Runs a 400mah 1s lipo. I would definitely have a collection of these for those micro plane weekend projects.

Does not come with calibration instructions. To calibrate the throttle settings. Set your TX throttle stick up to max. Plug in the ESC, then set throttle stick down to lowest setting.Works as advertised. Be careful of the voltage you give it. It works up to 4.8 volts and no more than that. Works with 4 AA batteries if you use rechargeable batteries that are only 1.2 volts each. (1.2 x4=4.8v) which is the rated max it works good at. Does not work if you use 4 AA Nicad batteries that are 1.5v each. (1.5x4=6v) which is too much voltage. At 6v the unit simply does nothing. It wasn't damaged though and worked as advertised when I used (4.8)v.

These are a low amp, small motor ESC. If you are using them within the 4A or less rating all is good. They have a smooth power delivery which is essential for my application. I purchased 2 packs of 3 and all 6 work as expected. Highly recommend for low amp small brushed motor applications. It is often difficult to get smooth control of very small motors (N20's) and these deliver that performance. Would I buy again? Yes, I just did.Additional information, I forgot to include in my original post that these were tested with a digital bench-top power supply and a digital electronic load in addition to battery and motor testing.

THEY DO NOT RUN THE MOTORS WITH ENOUGH CURRENT TO FLY EVEN THE LIGHTESS PLANE
