Frequently Asked Questions - Xrotor Micro Hobbywing

How do I charge the Xrotor Micro battery?

Connect the included USB charging cable to a standard USB power source (e.g., computer or wall adapter) and then to the battery. The LED will turn red during charging and green when fully charged. Charging takes about 40 minutes.

What is the flight time of the Xrotor Micro?

The flight time is approximately 5 minutes with the 300mAh battery. Allow the motors to cool for at least 15 minutes before recharging.

What is the maximum control range?

The control range is up to 100 meters in open outdoor areas with no signal interference. Indoor range may be reduced due to walls.

How do I bind the drone to the transmitter?

Turn on the controller first, then connect the drone's battery. Wait for the LED on the drone to stop flashing and become solid, indicating successful binding. If binding fails, turn off both and repeat.

What type of propellers does it use?

It uses 65mm plastic propellers (2 CW, 2 CCW). Replacement propellers can be purchased separately. Ensure to replace damaged propellers immediately.

Is the Xrotor Micro ready-to-fly out of the box?

Yes, it is a Ready-to-Fly (RTF) model. It includes everything needed: drone, controller, battery, charger, and propellers. You only need to supply 2 AA batteries for the controller.

How do I calibrate the drone?

Place the drone on a flat, level surface. Turn on the controller and drone. Push both joysticks to the lower right corner for 2 seconds until the drone's LED blinks quickly. The calibration is complete when the LED returns to solid.

Does the Xrotor Micro have a camera or FPV?

No, this model is a basic micro drone without a camera or FPV capability. It is designed for acrobatic flight and learning.

How do I replace a motor?

Remove the propeller and unscrew the two screws holding the motor in place. Disconnect the wire from the flight controller and install the new motor in reverse order. Ensure proper motor direction (CW/CCW) as marked.

What should I do if the drone does not take off or flies erratically?

First, check that the battery is fully charged and properly connected. Ensure propellers are correctly installed (blade side up) and not damaged. Re-calibrate the drone on a level surface. If problems persist, check motor wires and controller batteries.

    G --> H["8. Zero throttle detected (arming sequence end):"]

At this point throttle calibration values are stored. You may remove power from the ESC, or just continue running your ESC.

Attention!

1. This is an extremely powerful brushless motor system. We strongly recommend removing your propellers for your own safety and the safety of those around you before performing

2. Available throttle calibration range is from 1000us to 2000us, and the difference between minimum and maximum throttle must be more than 140us (70us in bidirectional mode). If a calibration is done where the difference is less than 140us (70us), the maximum will be shifted so that the difference is 140us (70us).

3. Oneshot125 mode works just the same as regular 1-2ms mode, the only difference is that all timing is divided by B. And the same for Oneshot42, where all timing is further divided by 3. Multshot also works similarly, except the input signal range is 5x25us.

4. Dshot is supported at any rate, up to at least Dshot1200. When the input signal is Dshot, throttle calibration is disabled, and the throttle calibration values are ignored.

5. Input signal rates up to at least 32kHz are supported. But please note that higher input signal rates put a heavier load on the MCU, and will reduce the maximum ERPM that the ESC can handle.

06 Programming parameters

1. Rampup Power:

Rampup power can be set to relative values from 3% to 150%. This is the maximum power that is allowed when ramping up at low RPMs and during start-up. For low RPMs, the maximum power to the

During startup, the actual applied power depends on throttle input, and can be lower than the maximum level set by the rampup power parameter, but the minimum level is a quarter of the maximum level. 2. Temperature Protection:

Temperature protection can be enabled or disabled. And the temperature threshold can be programmed. The programmable threshold is primarily meant as a support for hardware manufacturers to use, as different hardware can have different tolerances on the max temperatures of the various components used.

1. Low RPM Power Protection:

Power limiting for low RPMs can be enabled or disabled. Disabling it can be necessary in order to achieve full power on some low KV motors running on a low supply voltage. However, disabling it increases the risk of sync loss, with the possibility of toasting motor or ESC

1. Low Voltage Protection:

Low voltage protection can be set between 2.5V and 4.0V per LiPo cell. Or it can be disabled. When enabled, it will limit power applied to the motor if the battery voltage drops below the programmed threshold. This feature is primarily intended for fixed wing crafts.

1. Current Protection:

Current protection can be enabled to limit current. If enabled, then current will be limited to maximum the programmed value. The reaction time of the current limiting is quite fast, so current will also be limited during accelerations.

The value given for current protection, is per ESC. So if setting limit to e.g. 40A for each of the ESCs in a quad (using BLHeliSuite32), then the total current limit for the four ESCs will be 160A.

1. Motor Direction.

Motor direction can be set to fwd / rev / bidirectional / bidirectional rev.

In bidirectional mode, center throttle is zero and above is two rotation and below is reverse rotation. When bidirectional operation is selected, throttle calibration is unsabled. 7. Deman Compensation:

Demag compensation is a feature to protect from motor stalls caused by long winding demagnetization time after commutation. The typical symptom is motor stop or stutter upon quick throttle increase, particularly when running at a low RPM. As mentioned above, setting high commutation timing normally helps, but at the cost of efficiency.

Demag compensation is an alternative way of combating the issue. First of all, it detects when a demag situation occurs.

-In this situation, there is no info on motor timing, and commutation proceeds blindly with a predicted timing.

- In addition to this, motor power is cut off some time before the next commutation.

A metric is calculated that indicates how severe the demag situation is. The more severe the situation, the more power is cut off.

When delimag compensation is set to off, power is never cut.

When setting it to low or high, power is cut. For a high setting, power is cut more aggressively.

generally, a higher value of the compensation parameter gives better protection.

1. Motor Timing:

Motor timing can be set between approximately 10 and approximately 310 in approximately 10 increments (actual accurate values here are 15/16ths of a degree).

Typically a medium setting will work fine, but if the motor stutters it can be beneficial to increase timing. Some motors with high inductance can have a very long commutation demagnetization time.

This can refer to the order of a short open quick discount move, particularly which coming at a low rate. According to this high, it will offer more one for de-magnitudes, and often helps

This parameter can also be set to date. In this case the code monitors being installation time, and keeps timing as low as possible without having issues with de-mag. On well-accepted motors, timing can be low in the entire power range, and thereby max power can be reduced. On not so well behaved motors, timing is increased as needed, and thereby improves margins against sync loss.

1. Maximum Acceleration:

Maximum acceleration can be set between 0.1%/ms and 25.5%/ms. It can also be set to maximum, in which case acceleration is not limited. Limiting acceleration is primarily intended as a backup parameter that can be used in cases where too hard acceleration gives desyncs.

When setting to e.g. 10%/ms, it means that the power applied to the motor is not allowed to increase by more than 10% per millisecond.

1. Throttle Cal Enable:

If disabled, throttle calibration is disabled.

1. Minimum Throttle, Maximum Throttle and Center Throttle;

These settings set the throttle range of the ESC. Center throttle is only used for bidirectional operation. The values given for these settings are for a normal 1000us to 2000us input signal, and for the

For Dshot input signal, these settings have no effect

1. Brake On Stop:

Brake on stop can be set between 1% and 100%, or disabled. When not disabled, the given brake force will be applied when throttle is zero. For nonzero throttle, this setting has no effect. This feature is primarily intended for fixed wing crafts with folding props.

On some ESCs this setting is not linearly programmable, it will just be enabled (at 100% force for any setting 1%-100%) or disabled (this applies to ESCs that have "EN/PWM" style fet drivers).

1. LED Control:

LEDs can be controlled on ESCs that support it. Up to 4 LEDs can be turned on or off.

1. Beep Strength:

Sets the strength of beeps under normal operation.

1. Beacon Strength:

Sets the strength of beeps when beeping beacon beeps. The ESC will start beeping beacon beeps if the throttle signal has been zero for a given time. Note that setting a high beacon strength can cause hot motors or ESCs!

1. Beacon Delay:

Beacon delay sets the delay before beacon beeping starts

1. PWM frequency

Motor PWM frequency can be programmed between 16kHz and 48kHz. Higher PWM frequency can run motors smoother. Programmable frequency also allows for moving of small but potentially disturbing bumps in the throttle response. All ESCs have these bumps, with BLHeli_32 they can be moved in the RPM range, to a place where the system has low sensitivity to them.

07 Others

1. Thermal Protection

The ESC measures temperature within the MCU and limits motor power if the temperature is too high. Motor power is limited over a range;

-If the temperature is above the threshold, motor power begins to be limited.

-If the temperature is above the threshold plus approximately 150°C, motor power is limited to 25%.

Motor power is not limited below 25%.

1. Stall Protection

If the motor has attempted to start but not succeeded for a few seconds, it will stop attempting and wait for throttle to be zeroed before attempting again.

1. Beacon---Beeps

If the ESC is armed and sees zero throttle for a given time, it beeps beacon beeps, which are approximately one beep per three seconds.

1. Not activated ESC...Beeps

All ESCs shall be activated during manufacturing. If for some reason this is not done, the ESC will beep like this upon power up, before the normal operation beep sequence starts: "B, B, 8... (the time interval shortens gradually)". If for some reason activation has failed and the ESC is not regarded as a valid BLHeli_32 unit, the ESC will beep like this upon power up, before the normal operation beep sequence starts: "BBB, BBB, BBB" (the tone of the "BBB" changes from high to low). In this case the ESC will only accept 1-2ms nwm input signal.
