Ṣeto
1. Ayẹwo akọkọ
Carefully unbox the drone and inspect it for any visible damage during shipping. Ensure all wires are securely connected and there are no loose components.
2. Propeller fifi sori
Attach the propellers to the motors. Ensure the correct rotation direction for each propeller. Typically, propellers are marked (e.g., R for clockwise, L for counter-clockwise) or have different hub shapes. Refer to the motor rotation diagram if available in your flight controller software settings.

This image illustrates the proper method for attaching propellers to the drone's motors, ensuring they are oriented for correct thrust direction.
3. Battery Connection (XT30)
Connect a fully charged 4S LiPo battery (recommended 650mah-750mah) to the XT30 connector on the drone. Ensure the connection is firm. Always connect the battery last before flight and disconnect it first after flight.

This image demonstrates how to correctly connect the XT30 battery to the drone's power port.
4. Receiver Binding (ELRS2.4)
This variant comes with an ELRS2.4 receiver. To bind your ELRS radio transmitter to the drone, follow these general steps:
- Power on your ELRS radio transmitter and navigate to the ELRS LUA script.
- Power on the drone by connecting the battery. The receiver's LED should flash slowly.
- Initiate the binding process from your ELRS LUA script on the transmitter.
- The receiver LED on the drone should turn solid once successfully bound.
- If binding fails, cycle power on the drone three times rapidly (connect battery, disconnect, connect, disconnect, connect) to put the receiver into binding mode, then retry from the transmitter.
For PNP (Plug-N-Play) or TBS NanoRX variants, refer to their respective binding procedures.
5. Flight Controller Configuration
The drone is equipped with a Sub250 Redfox A3 45A AIO flight controller. It typically comes pre-configured. However, for advanced settings or troubleshooting, you may need to connect it to a computer using a USB cable and use flight controller software (e.g., Betaflight Configurator) to adjust parameters, calibrate sensors, or update firmware. Ensure you have the correct drivers installed.

- Ṣàyẹ̀wò àwọn propeller fún ìbàjẹ́ àti ìtọ́sọ́nà tó tọ́.
- Verify transmitter is powered on and bound to the drone.
- Confirm flight area is clear of obstacles and people.
- Perform a quick visual inspection for any loose wires or components.
2. Arming ati Disarming
The drone's motors will not spin until it is 'armed'. The default arming switch is typically configured on your radio transmitter. Consult your transmitter's manual or flight controller software settings for specific arming procedures. To disarm, use the same switch or a designated disarm command. Always disarm immediately after landing.
3. Ipilẹ Flight idari
Familiarize yourself with the basic controls on your radio transmitter:
- Ijoko: Controls altitude (left stick, vertical).
- Yaw: Rotates the drone horizontally (left stick, horizontal).
- Ipo: Tilts the drone forward/backward (right stick, vertical).
- Eerun: Tilts the drone left/right (right stick, horizontal).
Start with gentle movements in an open area until you are comfortable with the controls.

Itoju
1. Ninu
Regularly clean the drone to remove dirt, dust, and debris. Use a soft brush or compressed air. Avoid using liquids directly on electronic components.
2. Rirọpo propeller
Inspect propellers for cracks, bends, or nicks before each flight. Damaged propellers can cause instability and reduce flight performance. Replace any damaged propellers immediately with new ones of the same type and size (2*2.2*4).
3. Itọju batiri
- Store LiPo batteries in a cool, dry place at storage voltage (around 3.8V per cell).
- Never overcharge or over-discharge LiPo batteries.
- Do not use damaged or puffed batteries.
- Use a reputable LiPo charger with balancing capabilities.
4. Awọn imudojuiwọn famuwia
Lorekore ṣayẹwo olupese ká website or relevant flight controller software communities for firmware updates. Updating firmware can improve performance, add features, or fix bugs. Follow update instructions carefully to avoid bricking the flight controller.
Laasigbotitusita
- Drone won't arm: Check if the transmitter is bound, battery is connected, and all safety conditions (e.g., accelerometer calibration, arming switch position) are met in the flight controller software.
- Ọkọ ofurufu aiduroṣinṣin: Inspect propellers for damage, ensure motors are spinning freely, and check for correct flight controller orientation in software. Recalibrate accelerometer.
- No control input: Verify receiver binding and ensure the receiver is properly connected to the flight controller. Check channel mapping in flight controller software.
- Motors not spinning evenly: Check for bent motor shafts, debris in motors, or ESC calibration issues.
- Akoko ofurufu kukuru: Battery may be old or damaged, or propellers might be inefficient. Ensure battery is fully charged.
