Q1: I need an inspection drone for a heavy LiDAR and communications package. When does a 20-kilogram payload platform make sense?
A1: The UI20 is intended for missions that genuinely need a large payload: its specification lists up to 20 kg payload and 45.6 kg maximum takeoff weight. A lighter platform is usually easier to transport and regulate, so choose this size only after weighing the complete equipment stack.
Q2: Our custom inspection payload weighs 18 kilograms before cables and mounts. Can the inspection drone still carry the complete system?
A2: The UI20 lists 20 kg payload capacity, but the 18 kg sensor is not the complete installed load. Add mounts, cables, power converters, landing clearance and any secondary camera, then verify center of gravity, total takeoff weight and endurance with the manufacturer.
Q3: When the inspection drone carries the full 20-kilogram payload, what flight time should a contractor use for route planning?
A3: The UI20 specification lists about 20 minutes of endurance with a 20 kg payload and 65 minutes with no payload. Those figures still vary with speed, wind, temperature, battery condition, hover time and required landing reserve, so test the actual configuration.
Q4: For lighter inspection work, can the inspection drone really stay airborne for about an hour, or is that only a no-load figure?
A4: The UI20's 65-minute figure is explicitly listed for 0 kg payload. It should not be quoted for a camera, LiDAR, light or communications package; request or measure an endurance curve for the exact installed mass and route.
Q5: Two technicians need to move the inspection drone between substations. What are the folded dimensions and working weight?
A5: The UI20 is listed at about 720 × 720 × 650 mm with arms and propellers folded. Aircraft weight is about 13.5 kg without a battery and about 25.6 kg with one battery, before payload, case, controller and charger, so plan lifting and vehicle space carefully.
Q6: Our bridge inspection rig needs both a zoom camera and thermal sensor. Which inspection drone payload option combines those functions?
A6: The UI20 page lists the ZT30 four-sensor optical pod with a 30× optical camera, thermal sensor, additional wide camera and laser rangefinder. Its listed installed weight is about 854 g, leaving capacity for other equipment, but integration and data workflow still need verification.
Q7: For simple daylight construction photos, is there a lighter inspection drone camera than the large thermal and laser pod?
A7: The UI20 supports the A8 mini gimbal camera, listed at about 95 g with 4K video and 6× digital zoom. It is the lighter visual option when thermal imaging and laser ranging are not required, subject to the ordered mount and data interface.
Q8: At night we inspect a large rail yard. How much illumination can the inspection drone's high-power searchlight provide?
A8: The UI20 page lists a three-axis 300 W searchlight with 30,000 lm output and an illuminated area of about 706 m² at 100 m. The light weighs about 1.28 kg, and glare, shadows, power draw, flight time and night authorization must be evaluated.
Q9: During emergency inspections, can the heavy inspection drone broadcast live instructions as well as play stored messages?
A9: The UI20 page lists a quick-release speaker supporting real-time voice, uploaded audio, text-to-speech, alarms and stored playback, with up to 130 dBA maximum sound pressure and a stated 500 m effective broadcast distance. Actual intelligibility depends on wind and noise.
Q10: Our mountain corridor is exposed to crosswinds. Is a large inspection drone with only 6 m/s wind resistance suitable there?
A10: The UI20 specification lists maximum wind resistance of 6 m/s, lower than several smaller inspection models on the site. A heavy payload and large airframe require conservative gust and turbulence limits, so conduct a site wind study before selecting it for exposed mountain work.
Q11: Before quoting a 15-kilometer inspection drone route, how should we interpret the controller and flight-radius specifications?
A11: The UI20 specification lists a maximum configurable flight radius and MK32 transmission range of 15 km when unobstructed and interference-free, while another page module says 10 km. Neither is a guaranteed mission radius; use the current radio configuration, battery reserve, terrain and legal limits.
Q12: For repeatable LiDAR passes, can the heavy inspection drone use RTK, and what accuracy is stated?
A12: RTK is listed as an option for the UI20, with fixed accuracy of about 1 cm + 1 ppm horizontally and 1.5 cm + 1 ppm vertically. Survey accuracy still depends on correction quality, calibration, payload timing, trajectory processing and ground validation.
Q13: At an industrial site with cranes and cables, does this heavy inspection drone include obstacle avoidance as standard?
A13: The current UI20 specification and product sections do not establish a standard obstacle-avoidance system. Do not infer one from other products on the site; design routes, visual observation, stand-off distances and any added sensing around the actual ordered aircraft.
Q14: The product page calls the inspection drone body IP65. What should our rain-operation procedure assume?
A14: The UI20 marketing section describes an IP65 body, but the main aircraft specification does not repeat a complete system rating. Obtain written confirmation for the aircraft, battery connectors, payload and controller, and do not treat an ingress rating as permission to fly in unsafe rain.
Q15: We receive the inspection drone with two large batteries. Can the charger handle both at once, and what power supply is needed?
A15: The UI20 page lists two standard 70 Ah batteries and a UD2 charger by default. The charger is described as dual-channel with up to 3,000 W output, so confirm simultaneous-charge behavior, local input voltage, circuit capacity, grounding, connector type and cooling before installation.
Q16: If the inspection drone battery weighs around 15 kilograms, how should field crews handle transport, charging and replacement safely?
A16: The UI20 battery specification lists roughly 15.5 kg per 70 Ah pack. Use rated lifting and storage equipment, protect the terminals, follow temperature and state-of-charge rules, inspect the housing and connectors, and train crews for the manufacturer's approved installation procedure.
Q17: What exactly comes with the heavy inspection drone before we add a camera, LiDAR, speaker or searchlight?
A17: The UI20 page lists the complete aircraft, one MK32 remote controller, two standard 70 Ah batteries and one UD2 charger by default. Payloads, RTK, mounts, cases, generators and other field equipment should be confirmed separately in the selected variant and quotation.
Q18: Our control vehicle uses QGroundControl. Can the inspection drone controller run that software and display the payload video?
A18: The UI20's MK32 controller lists Android 9, a 7-inch display and compatibility with QGroundControl or Mission Planner for H.264 video. Confirm camera control, telemetry fields, codec, ports and the exact application version because basic video compatibility is not full payload integration.
Q19: During a long inspection shift, how many hours can the inspection drone controller operate before it needs charging?
A19: The UI20 MK32 controller specification lists a 10,200 mAh battery, about 10 hours of life and roughly 3.5 hours to charge with PD 30 W. Display brightness, radios, external devices and temperature can shorten the actual shift.
Q20: A university wants to test several heavy sensors on one inspection drone. What integration limits should the research team document?
A20: For the UI20, document total mass under 20 kg, takeoff weight under 45.6 kg, center of gravity, power demand, mechanical attachment, vibration, data interfaces, endurance and emergency jettison or landing plan. Research use does not remove aviation approval requirements.
Q21: We operate three heavy inspection drones from one depot. Which spares and maintenance tools should be standardized?
A21: For a UI20 fleet, standardize approved 70 Ah batteries, UD2 charging equipment, X9 Plus motors and 36-inch propellers, landing and folding hardware, payload mounts, controller accessories, connectors and inspection tools. Use the official life limits and service manual for replacement planning.
Q22: After carrying a maximum payload, which inspection drone components deserve an immediate post-flight check before another heavy lift?
A22: On the UI20, inspect propellers, motors, arms, folding locks, frame, landing gear, payload mount, fasteners, battery, high-current connectors and any gimbal or light. Record vibration or hard-landing events and follow the manufacturer's heavy-load maintenance interval.
Q23: Our aviation authority treats a 45-kilogram inspection drone differently from a small UAV. What approvals should the project check first?
A23: The UI20's listed maximum takeoff weight is 45.6 kg, so registration, pilot qualification, operational category, airworthiness evidence, remote identification, insurance and site permissions may differ materially by jurisdiction. Confirm the exact local rules before purchase or contract bidding.
Q24: A government infrastructure tender needs a 20-kilogram inspection drone. What acceptance tests would prevent an unsuitable system from being delivered?
A24: For the UI20, test the exact 20 kg mission payload, loaded endurance, wind limit, RTK, radio range, camera or LiDAR data, battery rotation, charger power, fail-safes and transport setup. Specify training, spares, documentation, maintenance, warranty and local approval as contract deliverables.
Q25: The insurer and bank are reviewing a heavy inspection drone purchase. Which risks belong in the ownership calculation?
A25: For the UI20, include payload integration, heavy batteries and charging infrastructure, transport and lifting, trained staffing, permits, insurance, maintenance, high-current components, spares, repairs and downtime. A 20 kg capacity creates opportunities, but it does not guarantee utilization or financial return.
