It can also be related to transport issues.
Cold temperature environmental conditions may require
sensitive electronic components to reach ideal operating
temperature slower as compared to under favourable
environmental conditions such as room temperature.
Under such cold conditions your unit may tend to drift in
any direction, increasing gradually. This can be avoided by
re-initializing the flight gyro after approx. 3 - 4 minutes into
flight. Small drifts in any direction are normal, however.
Drift may also be caused by propeller wash while flying
close to ground surface. Ideally, avoid operating the unit
in cold conditions (close to 32°F and 0 °C respectively) to
prevent product damage.
