User Guide

Wiring diagram

1. BEC output wire (red, brown): The additional BEC output wire is plugged into the receiver battery dedicated channel or any available channel. (For better BEC power output, it is recommended to insert the BEC cable into a battery-specific channel or any available channel)
2. RPM signal wire (yellow): electrical RPM output line of the motor needs to be connected to the RPM in of an external device (such as a Flybarless system gyro).
3. Throttle signal wire (white, red, black): Insert into the receiver throttle channel. Depending on the receiver type, the white wire is to transmit the throttle signal, whereas the red and black lines are parallel to the output of the internal BEC (e.g. the BEC voltage output wire and ground wire).

Normal boot process

Turn on the transmitter and push the throttle stick to the lowest point.

The ESC is connected to the battery, the motor will sound off with “123”, indicating that power turned on is normal.

A “beep” tone is sounded off to indicate the number of lithium batteries.

Finally, a long “beep” tone indicates that the ESC self-check is complete and the motor can be driven at any time.

Throttle stick calibration operation method

Turn on the transmitter and push the throttle to the 100% TH point.

ESC connect battery, motor will sound ” 123″, indicating that power turned on is normal

Then motor will sound off with a “beep-beep, indicating calibration for the highest point is successful.

Next, push the throttle stick to the minimum with in 5 seconds, and wait 1 second for the throttle lowest point to be calibrated successfully..

A “beep” tone is then sounded off to indicate the number of lithium batteries.

Finally, a “beep” tone indicates that the system is ready to take off at any time

• The ESC default throttle range is 1100µs-1940µs (Futaba standard). The throttle range should always be re-calibrated for the first time or when the transmitter has been replaced.
• Before calibration, always have the throttle curve set to default. Ensure that the throttle value corresponds to the highest point(100%) of the remote control throttle and the lowest throttle point (0%).

ESC programming and Data checking

• The ESC parameters can be programmed specifically to meet different flight needs.
• The ESC will be able to record the calibration speed of the current flight (only in storage Governor Mode), the minimum voltage, maximum temperature and other information.

Programmable parameters and instructions

Programmable parameters and parameter values

“*” in the form below indicate factory defaults.

Programmable parameters description

1. Flight mode

2. Fixed-wing mode: Suitable for fixed-wing aircrafts. In this mode, the throttle has to be more than 5% (including 5%) to start the motor and the throttle response is rapid.

3. Helicopter External Governor mode: Suitable for helicopters without any governor or helicopters using external governors. The throttle has to be higher than 5% (including 5%) before starting the motor. After the slow start is completed, the motor will start off with a smoother manner, followed by a faster throttle response accelerated to the current throttle value;

4. Helicopter Express Governor mode: Suitable for helicopters flying at a fixed headspeed. The throttle has to be higher than 40% (including 40%) before starting the motor. In the soft start process, the motor starts in an ultra-smooth acceleration to complete the speed calibration.

5. Helicopter Store Governor mode: Suitable for helicopters flying at a fixed headspeed. The throttle in this mode has to be more than 40% (including 40%) before starting the motor. The motor starts in an ultra-smooth manner. After the soft start, the governor will be activated.
   *Note that speed calibration must be done each time when other modes are switched to this mode.

6. LiPo cells
   The number of battery cells can be detected automatically, or set manually. Select Auto-calculation to calculate the number of battery cells automatically. Errors on battery cells will be detectable during self test and can be adjusted accordingly.

7. Low-Voltage Cutoff Type
   Soft   Cutoff: The output power will be gradually reduced to 50% of the total power output after low voltage protection is triggered.
   Hard Cutoff: Disconnect the power output immediately after low voltage protection is triggered.

8. Cutoff Voltage
   2.8V-3.8V per cell with 0.1V step adjustability. For example, When using 6S lithium batteries, the protection voltage should be set by ×6.

9. BEC Voltage
   The ESC is built-in with a BEC of 5-12V and has the capability to adjust 0.1v per step.

10. Response time
    Adjust the response speed of the throttle in “helicopter Express Governor” or “store Governor”. The higher the value, the slower the throttle response speed. 4-25 fully adjustable.

11. Governor parameter P
    This parameter is for controlling the ESC to compensate the amount of the motor speed during the process of maintaining the speed-governing effect; the higher the value, the bigger the amount; and vice versa. This function functions together with the Governor Parameter I.

12. Governor parameter I
    When the speed falls below, or exceeds the value set, the speed is compensated by the ESC. This parameter is used to resize the degree of rotation. Too large parameters will cause excessive make-up, and too small parameters will cause insufficient replacement.

13. Auto Restart Time
    This feature is only available in helicopter Express or Store Governor modes. It is the time set to push the throttle from more than 40% to 25% to 40% throttle range, and then push back more than 40%. The parameter will not take effect when the throttle range is below 25% or between 25%-40% beyond the set time. The ESC will execute the “helicopter Express / storage fixed speed” modes of the default start-up process only if the throttle range is above 40%.

14. Restart acceleration time
    1-3 seconds, with 0.5 seconds step adjustability . This parameter controls the time required for the motor to accelerate from zero to full speed during a quick restart. (This is an auxiliary function and is only valid if the “time to turn off and land” function is valid)

15. Brake types
    Normal brake: This function will stop the motor from braking during operating according to the value set on the braking force.

16. Brake Force
    The greater the value, the shorter the time taken for the motor to come to a standstill. 0-100%, with 1% step adjustability. This function is only valid in normal brake mode.

17. Timing
    This item is for adjusting the ESC timing. It’s adjustable between 0 and 30° with the step of 1°.

18. Motor direction
    This item is for setting the rotation direction of the motor, and it’s “CW” by default. After connecting the motor to the ESC, (if the motor rotates clockwise); when setting this item to “CCW”, the motor will rotate counterclockwise; (if the motor rotates counterclockwise), when setting this item to “CCW”, the motor will rotate clockwise.

19. Active Freewheeling
    This item can be enabled or disabled when the “Flight Mode” is set to the “Fixed-wing” or “Helicopter (External Governor) mode; it’s fixed at “Enabled” when the “Flight Mode” is set to the “Helicopter (Elf Governor)” or“Helicopter (Store Governor)” mode. With this item enabled, the throttle linearity will be great.

20. Start-up force
    This item is for adjusting the start-up force of the motor (during the start- up process). The higher the value, the larger the start-up force. It’s adjustable between 1 and 7.

Speed Governor Function

Explanation for the ESC Speed-governing

Establish the “Motor RPM-Throttle Amount Curve” via the speed standardization, and then set the throttle amount to some fixed value on the transmitter, in that condition, the motor will output the RPM corresponds to the throttle amount and keep rotating at that speed.

• In the “Helicopter (Express Governor)” mode, the ESC won’t save the “Motor RPM-Throttle” curve after it’s disconnected from the battery, so every time when the ESC is connected to the battery, it will standardize the speed, otherwise you cannot use the speed-governing function normally. In this mode, due to the differences like batteries’ discharge capacities, the standardized RPM is a little different every time. In consequence, at the same throttle amount, the RPM may be a bit different when using different batteries, but this won’t affect the speed governing effect.
• In the “Helicopter (Store Governor)” mode, the ESC will save the “Motor RPM-Throttle” curve after the speed standardization. So after adjusting to this mode from any other mode, you need to standardize the speed when the ESC is connected to the battery for the first time and you needn’t standardize the speed again after disconnecting the ESC from the battery first and then connecting it to the battery again. If adjusting to any other mode from this mode and saving the “Motor RPM-Throttle” curve, and then adjusting back to this mode, the “Motor RPM Throttle” curve saved by the ESC will be cleared, and you need to standardize the speed once again. If your ESC remains in this mode in future, then it will always carry out its operation as per the saved “Motor RPM-Throttle” curve. When standardizing the speed for the first time, we recommend using a battery in good condition. Afterthe RPM standardization, change another battery with the same number of cells to fly your aircraft. At the same throttle amount, the RPM should be consistent with the RPM of the first flight.

RPM Standardization

1. The principle of RPM Standardization
   During the RPM standardization, the ESC will establish a “Motor RPM-Throttle” curve by itself based on the actual battery voltage and the actual KV rating of the motor. Therefore , you need to standardize the speed with a fully charged battery, and ensure the main blade pitch is 0° (in order to make the helicopter not take off). In general, people use the default “Throttle Curve & Pitch Curve” of the transmitter (as shown below) when they standardize the speed. Attention! Please ensure the main blade pitch is 0° and the throttle amount is above 40% (we recommend using 50%) when standardizing the speed.

2. Procedures of RPM Standardization

   • We recommend using the default “Throttle Curve & Pitch Curve”. ( If you don’t want to use the default setting, then please ensure the throttle amount is 50% and the main blade pitch is 0° when the motor rotates.
   • Turn on the transmitter, move the throttle stick to the bottom position and then wait for the ESC completing the self detection.
   • If you’ve set the “throttle cut” function, please lock the “throttle cut”, and then move the throttle stick to the 50% position and then unlock the “throttle cut”. If there is no “throttle cut”, then you can move the throttle stick to the 50% position directly.
   • The ESC drives the motor to rotate, the main blades start to accelerate slowly (because the main blade pitch is 0°, so the helicopter won’t take off, but you still needs to be careful), you need to wait for the acceleration completing and the speed getting stable, and then lock the “throttle cut” or move the throttle stick to the bottom position.
   • The ESC will stop driving the motor, the main blades start to slow down and then stop rotating.
   • The RPM standardization completes.
     
     

Attention! Please calibrate the throttle range before the RPM standardization. There will be no need if you’ve carried out the ESC/Radio Calibration when the first time you used this the ESC or you didn’t restore the settings to factory defaults after the calibration (changing the transmitter & receiver is an exception).

How to Set the Governor

• The best throttle amount (set in the Helicopter “Store Governor” mode) of the ESC ranges from 70% to 90%, so please try to set the throttle amount (set in the Helicopter “Store Governor” mode) within this range. A low throttle amount (set in the Helicopter “Store Governor” mode) will make the ESC always function inefficiently; while a high throttle amount (set in the Helicopter “Store Governor” mode) will leave the ESC a very small compensation space, then compensation insufficiency issue may happen and cause (speed decrease) problem when the load is high. In that case, we recommend changing the motor or drive gear ratio (you need to re standardize the speed after you change the motor or drive gear ratio).
• In the “Helicopter (Store Governor)” mode, if fly your aircraft with a low performance battery after standardizing the speed with a high performance battery may cause damage to the low performance battery.
• In “Helicopter (Store Governor)” mode, different battery packs can bring the same stable RPM only if they have the same cell count. This won’t change even when you change the battery pack. However, battery packs with different cell count don’t have the same effect. For instance, in “Helicopter (Store Governor)” mode, you can`t use a 4S to calibrate the motor RPM and then use a 6S to drive the motor, hoping it can run at the same RPM.
• You can decide the control feel via adjusting Governor Parameter P/I. In “Helicopter (Store Governor) or Helicopter (Express Governor)” mode, connect your ESC to a smart phone or PC, then you can check the “throttle vs speed” chart.

1. In “Helicopter (Store Governor)” mode, you can check the standardized speed (Max. RPM) and needn’t standardize the speed every time when the ESC is connected to the battery as in the “Helicopter (Express Governor)” mode, so it’s more convenient. We recommend using this mode in the condition that you’re using fixed motor, drive gear ratio and battery (with same cell count). In this mode, only if the drive gear ratio is accurate, the main blades’ RPM corresponds to the throttle amount (set in the Helicopter “Store Governor” mode) that you will get will be accurate as well. About how to “set the speed-governing function” in this mode, let’s take an example .1.

   • In “Helicopter (Store Governor)” mode, connect the ESC to the LCD program box or WIFI Express module when the RPM standardization completes, and then find the record (as shown below) as per the instruction about the “ data checking” process.
     The value shown in the image is just an example, pleas take the value actually displayed on your LCD program box as standard. This value is the max. electrical RPM and the motor can reach at the 100% throttle.

   • Take a helicopter with single reduction gear unit as an example, the motor poles is 10, the motor drive gear is 13T and the main drive gear is 120T (that the drive gear ratio is 9.3), and then you can get the main blades’ RPM at the 100% throttle.
     Formula: Main Blades’ RPM (at the 100% throttle)=Max. RPM÷ (Motor Poles ÷2)÷Drive Gear Ratio The Main Blades’ RPM (at the 100% throttle) in the example is: 157*1000÷(10÷2)÷(120÷13)≈3400 RPM If the Main Blades’ RPM needs to remain at 2700RPM during the 3D flight process, then you need to set the throttle amount (set in the Helicopter “Store Governor” mode) to 2700÷3400≈ 0.8, that is you need to set the throttle amount to 80%. At this time, you need to set the value of the 3D throttle curve (i.e. IDLE1) to 80% (as shown below):So next time, when you fly your helicopter, let it take off in the “Normal” mode first and then switch to the “IDLE1” mode directly, then your helicopter can start the 3D flight with 80% throttle amount (that’s the standardized speed of 2700 RPM).
     Notes: in general, you can set and save 2/3 sets of throttle curve IDLE settings on a high quality transmitter (and you need to adjust the main blade pitch of each set of IDLE setting as per the actual demand), and switch between these settings during the flight and have the different throttle amount (set in the Helicopter “Store Governor” mode) to meet the different RPM demands (i.e. when setting IDLE1 to 70%, IDLE2 to 80%, IDLE3 to 90% in the way as explained earlier, then you will have three different throttle amounts (set in the Helicopter “Store Governor” mode) to meet different flight demands.

2. In the “Helicopter (Express Governor)” mode, you are not allowed to check the Max. RPM, so you need to set the transmitter in advance and check the main blades’ RPM with the help of some external device (like RPM viewer) and then decide the throttle amount that you need to set. Here you can calculate the throttle amount roughly. For example, if the KV rating of the motor is 480KV, the battery is a 12S LiPo, the motor drive gear is 13T and the main drive gear is 110T, then the main blades’ RPM is: KV Rating × Battery Voltage ÷Drive Gear Ratio (480124.2*13÷110≈2850). So if you want your motor to rotate at the speed of 2150RPM, then the throttle mount is: 2150÷2850≈0.75 (that is 75%), and then you adjust it accordingly as per your preference or the data you read on the RPM viewer
   

Warning Tones and Protection

1. LED indicators and warning notes
   Protection| Tone| LED indicator| Instruction
   ---|---|---|---
   The input voltage is abnormal| “BB, BB, BB, BB…”| Red LED, followed by the tone| The input voltage is not within the input voltage range
   Throttle signal loss| “B,—,B,—,B,—…| Red LED, followed by the tone| The throttle signal input was not detected
   The throttle stick is not moved to the 0% position.| “B, B, B, B…”| Red LED, followed by the tone| The throttle value is not at 0% throttle
   The throttle range is too small| “B, B, B, B…”| Red LED, followed by the tone| When calibrating the throttle stroke, set the throttle travel too small
   Temperature protection| “BB, BB, …” or “BBB, BBB…”| Red LED, followed by the tone| The internal temperature of the ESC exceeds the protection temperature
   Low voltage protection| “BBBB, BBBB…”| Red LED, followed by the tone| The operating voltage is lower than the set protection voltage
   Current protection| None| Red is always bright| The operating current is higher than the set current

2. Protection function description

   • Abnormal power-on voltage protection
     The ESC enters a protective state once the input voltage detected is not in the operating range. Prompting LED light to flash.

   • Start-up protection
     The start-up protection will be able to detect the motor speed from when the speed stops rising or the rising speed is unstable. If the throttle input is less than 15%, the ESC will try to restart automatically; (This may occur due to; Poor contact between the ESC and motor connections, individual output wires, faulty motor, propellers blocked by other objects, Binding gears, etc.)

   • Temperature protection
     When the operating temperature of the ESC has exceeded 110 degrees Celsius, power will be gradually reduced for safety, but will not be turned off. There will still be up to 50% of power, to ensure that the motor has the power to land.
     After the temperature drops, the ESC will gradually be restored back to maximum power. The ESC temperature must not exceed 70 degrees or it will not work. Prompting LED light to flash (above is the soft-off protection mode, if you choose hard-off, cut off the power directly)

   • Throttle signal loss protection
     When the throttle signal is lost for more than 0.25 seconds, the output is immediately switched off to avoid further damage due to the propeller rotating at a high speed. Once the signal has been restored, the power output will be restored.

   • Overloading protection
     When there is a sudden surge of current, power will be cut off and will be restarted. If the load is still abnormal after the restart, the power will be completely cut off.

   • Low voltage cutoff protection
     When the operating voltage of the ESC has exceeded the protection voltage set, power will be gradually reduced for safety, but will not be turned off. There will still be up to 50% of power, to ensure that the motor has the power to land.

   • Over-current protection
     The current will be cut off immediately once the set value has been breached.
