Common faults
This section helps you understand what is happening with your drone and decide whether to fix it yourself or take it to a service centre. The descriptions are general: see the manual for the steps for your model.
Drift and unstable flight
What to do
Replace the propellers, calibrate according to the manual, take off away from metal structures.
Signal loss
Possible causes
Obstacles between the controller and the drone, radio interference, excessive range.
What to do
Set the altitude and signal-loss behaviour in advance; keep the drone within visual line of sight.
GPS and compass
Possible causes
Too few satellites, interference, flying near buildings or metal.
What to do
Wait for a stable signal before take-off; if there are compass warnings, do not take off.
Battery
Possible causes
Wear, cold, improper storage.
What to do
In cold weather keep batteries warm until take-off and shorten flights; take a swollen battery out of service.
