Maintenance guide
Drone maintenance checklist.
By the NVX engineering team, New Delhi
Most drone crashes and costly repairs start with something a quick check would have caught: a chipped propeller, a loose connector or a tired battery. Use these checklists before and after every flight, every month and before storage. Always follow your manufacturer's manual where it differs.
Pre-flight checklist
Two to five minutes before every flight.
Propellers
No chips, cracks or bends; mounted firmly in the correct direction.
Airframe and arms
Arms locked, no cracks, landing gear secure, nothing loose.
Battery
Fully charged, no swelling or damage, latched firmly; controller charged too.
Sensors and calibration
Compass, IMU and gimbal show no errors; calibrate away from metal if asked.
Home point and failsafe
Home point recorded, return-to-home altitude set above local obstacles.
Post-flight checklist
After landing, before packing up.
Let it cool
The motors and batteries get hot; let them cool before handling and charging.
Inspect for damage
Look over propellers, arms, gimbal and camera for any impact marks.
Clean
Remove dust, grass and moisture; for spray drones, rinse the tank, pump, lines and nozzles.
Check motors
Spin each motor by hand; it should turn smoothly without grit or noise.
Note anomalies
Log any warnings, odd sounds or drifting so they can be checked.
Monthly checklist
Or every 20 to 30 flight hours for working drones.
Firmware
Update drone, controller and battery firmware from official sources, then test-fly in a safe area.
Fasteners and connectors
Check screws, plugs and cable ties for looseness or corrosion.
Battery health
Review cycle count and cell balance in the app; retire weak packs.
Propeller replacement
Replace propellers on a schedule, not only after damage.
Logs review
Look for repeated warnings in flight logs.
Storage checklist
For breaks of more than a week or two, and through the monsoon.
Storage charge
Store batteries at storage level, roughly half charge, never full or empty.
Cool and dry
Keep the drone and batteries away from heat, direct sun and humidity; use silica gel in the case.
Gimbal lock
Fit the gimbal cover or lock to protect the camera.
Periodic checks
Check battery levels every few weeks and top up to storage charge.
When to call a technician
Stop flying and book an inspection after any crash or water exposure, or if you see motor or ESC errors, persistent compass or IMU warnings, gimbal faults, a swollen battery or unexplained drifting. NVX repairs DJI, FPV, agriculture and enterprise drones, with a quote before any work.
FAQ
Maintenance Checklist: common questions
How often should a drone be serviced?
Do quick checks every flight and a deeper check monthly or every 20 to 30 flight hours for working drones. Follow the manufacturer's schedule where it exists.
How often should I replace propellers?
Immediately if chipped, cracked or bent, and on a regular schedule for working drones even if they look fine.
How do I clean a drone after flying in dust?
Use a soft brush and air blower; do not use water on electronics. Spray drone tanks and lines can be rinsed with clean water.
Should I update drone firmware?
Yes, from official sources, but read the release notes and test-fly in a safe area afterwards.
Can NVX service my drone?
Yes. NVX repairs and maintains camera, FPV, agriculture and enterprise drones from Connaught Place, New Delhi, with courier support across India.
