32 | Low Altitude Control – Min. Height
22. Low Altitude Control – Min. height
■
Low Altitude Control settings are available in the EYEControl:Navigator app.
■
Low Altitude Control only restricts the minimum altitude.
■
Accuracy: ±2 m, min. height: 5 m
Important! In order to fly lower than the set min. height
you must keep the throttle stick at its miniumum position for
min. 5 seconds.
■
Low Altitude Control can only be activated in GPS flight mode (and ‘Safe bank’) .
■
Switching to another flight mode deactivates Low Altitude Control.
22.1 Avoid crashes
■
Study »Fig. 15.
The Low Altitude Control is controlled by atmospheric pressure. When you connect the
battery in a certain place the atmospheric pressure is measured and taken as ‘zero’ value,
from which the min. height is calculated.
Example:
▬
Min. height set in app: 40 m
▬
Height above sea level: 1000 m
Once the Navigator 250 surpasses 40 m (actual 1040 m), Low Altitude Control is triggered
and the Navigator 250 will not descend lower than the 40 m mark (± 2 m).
The pilot must be aware that the Navigator 250 does not consider obstacles that are within
the set height and can therefore easily crash into objects in its path (see »Fig. 15).
23. Maintenance, care and repair
We provide video instructions for many spare parts. View
them on www.rclogger.com. If instructions are available,
follow them with precision.
23.1 Regular cleaning and maintenance
23.1.1 Cleaning
The Navigator 250 is a simple but well-designed flying device. There are no mechanical
parts that need to be lubricated or require special maintenance. However, after each flight
you should clean the Navigator 250 of possible dirt (wool strings, dust, etc.).
For cleaning, use a dry or slightly damp cloth and avoid contact between water and the
electronics, rechargeable battery and motors.
23.1.2 Maintenance and repairs
Defective components present a hazard. Replace all damaged components before flying
the Navigator 250 again. It is important that you only use original spare parts. Non-original
spare parts can lead to damage and accidents, or may not be of sufficient quality.
23.2 Drift
■
Cold temperature environmental conditions may require sensitive electronic
components to reach ideal operating temperature slower as compared to under
favourable conditions such as room temperature.
■
Under such cold conditions your unit may tend to drift in any direction, increasing
gradually. Small drifts in any direction are normal, however. Drift may also be caused by
propeller wash while flying close to ground surface. Operate the Navigator 250 within
the temperature range given in the technical data.
If you need to continuously trim the Navigator 250 to ensure proper flying then this may be
due to one of the following reasons:
