How much has it flown?
Ask about flight time, number of flights and records in the flight app. High hours are not automatically bad, but make battery, motor and hinge wear more likely.
This guide uses Dutch and European references. Before flying elsewhere, check the rules and registration requirements for your destination.

A drone may look undamaged yet have suffered a hard landing, worn batteries, a crooked gimbal or unreliable sensors. Check the entire flight system as well as the images.

Before you leave
Ask about model, use and damage first.
'DJI Mini' or 'Mavic' is not specific enough. Versions differ in weight, camera, sensors, controller, battery and European drone class. Ask for photos of the model number, serial number and any C0, C1, C2, C3 or C4 label.
Has it ever crashed?
Ask explicitly about collisions, hard landings, water, sand and repairs. 'Only a propeller was hit' can also mean a bent motor shaft, damaged arm or misaligned gimbal.
Which version are you buying?
Check the exact drone, controller and included batteries. A similar controller or battery may physically fit without supporting all the model's functions.
What is included?
Agree how many batteries, propellers, cables, chargers, charging hubs, gimbal protectors, bags, filters, memory cards and purchase documents are included.
The most expensive surprises
Batteries and previous damage
deserve extra attention.
A worn battery does more than shorten flight time. Voltage drops or sudden failure can crash the drone. An earlier crash may also have left hidden damage.
Inspect each battery separately
Look for swelling, cracks, dents, leaks, burnt contacts and damaged catches. A battery should sit flat and click in without force.
Ask about charge cycles
Where available, check cycles, errors and cell voltages in the official app. Large differences between cells or a rapidly falling percentage are warning signs.
Check arms and hinges
Unfold all arms gently. Look for hairline cracks near screws, colour differences, glue, play and arms that feel different from the others.
Turn the motors by hand
With the drone switched off, motors should turn evenly without scraping. Resistance, sideways play or unusual noise may indicate damaged bearings or a bent shaft.
Inspect the whole system
Six components to test every time.
Propellers
Check each propeller for cracks, white stress marks, chips, bending and incorrect mounting. Replace damaged propellers before a test flight.
Camera & gimbal
Look for lens scratches and condensation. Switch on: the gimbal should initialise smoothly, finish level and move without clicking or shaking.
Sensors
Clean vision, distance and infrared sensors and inspect for cracks. Check the app for compass, IMU, GPS and obstacle detection errors.
Controller
Test both sticks through their full range, every button, dial, antenna, port, screen and battery. Sticks should return neatly to centre.
Storage & connection
Record video at your desired maximum quality, take photos and play files back. Check the card slot, internal storage and live connection stability.
Serial number & firmware
Compare serial numbers on the drone, app, packaging and receipt. Check that drone, controller and batteries are recognised normally with no unexplained warnings.
Only where safe and permitted
Make a gentle test flight.
Fly low with plenty of clear space and undamaged propellers. If unsure, let the seller take off first. A minute of hovering reveals much about motors, positioning and gimbal.
- 01
Read the messages
Wait for sufficient satellites and check home point, compass, IMU, battery and calibration messages. Never ignore red or recurring warnings.
- 02
Hover at eye level
The drone should hold height and position reasonably steadily. Strong drift, shaking, pulsing or one unusual motor sound needs investigation.
- 03
Fly in every direction
Gently test ascent, descent, turning and short movements forward, backwards and sideways. Responses should be predictable and movement should stop when you release the sticks.
- 04
Test camera and gimbal
Take photos and video while turning and moving. Look for a tilted horizon, shaking image, focus problems, marks and jerky gimbal movement.
- 05
Check battery and heat
After landing, check consumption and carefully feel battery and motors. One much hotter motor, an error or a sudden percentage drop is suspicious.
- 06
Release the account binding
If the brand uses account binding, have the seller remove the drone and controller from their account. Then check you can activate and pair the system yourself.

Reasons to walk away.
- 01A battery is swollen, damaged, unusually hot or shows cell or voltage errors.
- 02Arms, motor mounts or casing have cracks, glue marks or obvious deformation.
- 03The gimbal initialises incorrectly, shakes, clicks or stays tilted.
- 04The app repeatedly reports motor, ESC, compass, IMU, GPS or sensor errors.
- 05The serial number, drone class, receipt or explanation of previous damage does not add up.
- 06The seller refuses a safe test flight or cannot remove account binding.

This check helps you inspect carefully but does not replace a technical inspection or knowledge of current flight rules. If unsure about an expensive or visibly repaired drone, consult a specialist.
