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 y 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 ight mode (and ‘Safe bank’).
Switchingtoanotheright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yingdevice.Therearenomechanical
partsthatneedtobelubricatedorrequirespecialmaintenance.However,aftereachight
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ying
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sufcient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ying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yingthenthismaybe
duetooneofthefollowingreasons:
