A used drone can save you a lot of money, but a few problems are expensive to fix and easy to miss. Use this checklist in person, or ask the seller for the same evidence in photos and video if you are buying remotely.
Account lock: check this first
Many drones are linked to the account that activated them. Ask the seller to confirm it has been unlinked, or to unlink it in front of you after a test flight. A drone you cannot activate is a paperweight.
Batteries
- Ask for the cycle count and health for every battery, shown in the app
- Look for swelling, dents or a case that does not sit flush
- Batteries that drain fast at rest or show cell imbalance are near the end of their life
- Price in replacement packs if cycle counts are high
Gimbal and camera
- Power on and confirm the gimbal self-calibrates without shaking, buzzing or error messages
- Check the lens for scratches and the gimbal cover for cracks
- Record a short clip and look for horizon tilt, jello or focus problems
Motors, arms and body
- Spin each motor by hand: it should turn smoothly with no grinding
- Check arms and hinges for cracks, glue or looseness
- Look for scuffs on the bottom shell and sensors, a common sign of hard landings
- Props should be undamaged; replacements are cheap but chips suggest crashes
Flight test
If you can, fly it. It should hold position steadily in a hover, respond cleanly to stick input and return without warnings. Errors about the IMU, compass or vision sensors deserve a closer look before you pay.
Paperwork, Remote ID and registration (US)
- A receipt or proof of purchase helps confirm it is not stolen
- Ask whether there is any remaining manufacturer warranty or protection plan, and whether it transfers
- Drones that require FAA registration must broadcast Remote ID, either built in or with a module
- Register the drone under your own name before you fly it
Paying safely
Meet in a public place for local sales and use a traceable payment method. Avoid deals that push you to pay off-platform before you have seen the drone, or prices far below the going rate for that model.
