Product Features
1. Safe power-on function: When the power is turned on, the motor will not start immediately regardless of the position of the throttle stick to avoid personal injury;
2. Throttle stroke adjustment function: adapt to different remote control oil
The difference in door stroke improves the linearity of throttle response, with smooth and delicate speed control feel and speed control linearity;
3. Program setting items:
Brake setting: no brake/with brake, the factory default is no brake.
Battery type: Li-xx (lithium battery) / Ni-xx (nickel cadmium or nickel metal hydride), the default value is Li-xx (lithium battery).
Low voltage protection mode: reduce power/turn off output, the default value is to reduce power.
Low voltage protection threshold: low/medium/high, the default value is the middle cut-off voltage.
When it is set to use Li-xx batteries, it will automatically determine the number of lithium batteries. The cut-off voltage of each battery under low/medium/high conditions are: 2.6V, 2.85V, 3.1V.
When it is set to use Ni-xx batteries, the ESC will automatically detect the voltage of the battery pack when it is powered on. The cut-off voltage for low/medium/high conditions is 0%, 45%, 60% of the input voltage at startup (0% means Don’t do low-voltage protection)
Start mode: normal/soft/super soft start, the default value is normal start.
Normal start is suitable for fixed wing, and the motor can be started quickly within 0.2 seconds
Soft start/super soft start is suitable for helicopters; the initial speeds of soft start and super soft start are both relatively low. It takes 1 second and 2 seconds from start to full speed, but if the throttle is turned off after starting, it will be restarted within 3 seconds. All start in normal mode to avoid crashing due to slow reaction when doing some aerobatics flying.
Timing angle: low/medium/high, the default value is medium timing.
Under normal circumstances, low timing can accommodate more motors, but in order to improve efficiency, it is recommended to use low timing for 2-pole motors and medium timing for motors with 6 poles or more. To increase the speed, the timing can be set to a high timing. After changing the angle setting, you should test on the ground before flying.

4. Comprehensive protection function:
Undervoltage protection: set by the user through the program;
Overvoltage protection: The input voltage will not start when the input voltage exceeds 18 volts, and it will be automatically protected. At the same time, a rapid "beep beep" warning sound will be emitted;
Overheat protection: Built-in temperature detection circuit, the ESC will automatically shut down when the temperature of the MOS tube is too high;
Remote control signal loss protection: reduce the power after the remote control signal is lost for 1 second, and turn off the output if there is no remote control signal for another 2 seconds;
Process characteristics
1 The power input terminal adopts ultra-low impedance and large-capacity electrolytic capacitors, which greatly improves the anti-interference ability;
2 The output MOSFET power tube is equipped with an independent heat sink to reduce the temperature rise of the device and improve the system's high-current working ability;
3 Using single-chip microcomputer control;
4 The single-chip microcomputer adopts an independent voltage regulator chip to avoid power interference caused by BEC load changes and improve the stability of the single-chip microcomputer;

Setting method
1. Turn on the transmitter and push the throttle to high (FUTABA series transmitters need to use REV as the throttle channel).
2. Connect the receiver and motor.
3. When the ESC is turned on and the transmitter is normal, there will be the following sound: (If there is a long "di" sound after the sound is over, there will be no sound later, then check the transmitter throttle channel reverse setting.)
B B means LIPO automatic protection
BB BB means NIMH/NICD automatic protection
BBB BBB means brake selection
(When there is no operation, all sounds will continue to loop until there is an operation request.)
There are settings you want during the sound cycle. When you hear the syllable of the prompt sound, (for example, select LIPO automatic protection, when you hear a B, the throttle is pulled to the low position) quickly pull the throttle to the low position. At the same time, the motor will make a very sharp sound to confirm.
At this time, if there are other settings, quickly push the throttle to the maximum, then you can select the next option.
If the setting you want is completed, wait for 2 seconds, the motor will sound the appropriate battery protection confirmation sound again, and confirm the throttle position before you can use it.
LIPO automatic protection has only 2 protection voltage protection points, namely 6V and 9V. The battery can be used without a fully charged battery.
NIMH automatic protection is calculated according to the actual number of batteries. Each battery is set to 0.8V. In order to accurately determine the voltage of the battery, please fully charge the battery. If it is not fully charged, the ESC will estimate the protection voltage based on 70% of the voltage. (This function can also be used when using 4LIPO)
The factory setting is none. You can do a brake setting operation during actual use, so that the motor will use the back electromotive force to brake after closing the throttle.
If you want to release the brake function, you can set the brake operation again, then the function will be cancelled.
Factory parameter reset function, because this series of ESCs has overheating and misoperation protection functions, if you find that your ESC accelerates, or turns, or any characteristics such as the throttle curve have changed when new, then you can do it once Factory parameter settings to regain high performance.
When it is turned on, there is a long beep of B, indicating that the ESC is in the LIPO automatic protection state, and three beeps of BBB, indicating the NIMH/NICD automatic protection state.

Use common sense: (literacy)
Some players picked up the ESC and installed it directly on the plane, but when they heard a beep, the motor just didn't rotate or the speed could not go up. The reasons are as follows:
To use the ESC for the second time, you need to identify the remote control's large and small strokes. The method is as follows:
Connect the ESC to the motor----connect the ESC cable to the receiver-----Turn on the remote control and push the throttle to high point----plug the ESC to the battery----- --Listen to the sound----Music (123)-----Didi (confirmation sound of high throttle)----After two beeps, pull the throttle stick to the low point-----heard didi Three beeps ---- (throttle low point confirmation, 2S two beeps, 3S three beeps) -----OK
The three wires of the brushless ESC can be connected arbitrarily. If the steering is wrong, just swap any two of them.
