For the ELRS 2.4G version, follow the standard ExpressLRS binding procedure for your specific radio transmitter. Typically, this involves powering on the drone three times consecutively, waiting for the LED to flash rapidly, then initiating the binding process on your transmitter. Refer to your ExpressLRS module manual for detailed instructions.
3.4 Першапачатковыя праверкі
Before the first flight, perform the following checks:
- Verify all screws are tightened.
- Пераканайцеся, што прапелеры надзейна замацаваны і не маюць пашкоджанняў.
- Confirm the flight controller (FC) is properly configured and calibrated using Betaflight or a similar configurator.
- Check that the O4 Air Unit Pro is functioning and transmitting video feed.
- Perform a range check with your radio transmitter.
4. Інструкцыя па эксплуатацыі
4.1 Перадпалётны кантрольны спіс
- Праверце аб'ём батарэіtage on both drone and radio transmitter.
- Inspect propellers for any cracks or damage.
- Ensure the flight area is clear of obstacles and people.
- Confirm GPS lock (if applicable and configured) and home point set.
- Verify video feed quality from the O4 Air Unit Pro.
4.2 Узлёт і пасадка
Arm the motors using the designated switch on your radio transmitter. Slowly increase throttle to lift off. Maintain a stable hover before proceeding with flight maneuvers. For landing, slowly decrease throttle while maintaining control, aiming for a soft touchdown. Disarm motors immediately after landing.
