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 unidirectional brushed ESC.

Parameter:
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 start 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.

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.

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
