18. Selecting a flight mode
18.1 GPS mode
In the GPS mode the Navigator 250 holds a set position (x, y,and z-axis). The GPS
functioncontrolsandmakesadjustmentstoallthreeaxes.
1. Activate the Basic mode.
2. Lift the Navigator 250 up to the desired altitude and position it. Move the throttle
towards its centre position.
3. ActivatetheGPSmodeonyourtransmitter.
4. TheNavigator250nowholdshorizontalpositionandaltitude.
5. Correct the position as desired.
6. ChangeightmodestodeactivatetheGPSmode.
TheGPSsignal strength isindicatedbythe rear LEDs. Dependingonthe GPS signal
strengththesolidLEDisinterruptedbydistinctblinkpatterns,whicharesummarizedin

18.2 Basic mode
■
The basic mode is designed specically for users who are new to ying multirotor
systemsandthosewholookforintuitivecontrolsforaerialphotography.
■
Thecontrolsrespondlessaggressively.Thisbehaviourisintentional,allowingpilotsto
getarstfeelingofhowtheNavigator250respondstoleverinput.
■
Auto-Levellingisenabled.Itmeansthatifthepilotletsgooftheaileronandelevator
controlstick,theNavigator250regainsarelativehorizontallevelposition.Smalldrifts
inanydirectionarenormal,especiallyduringnotfullycalmconditions.
■
WerecommendthismodewhenyouintendtouseacameraorFPVequipment.Motor
power is restricted for smoother operation and less aggressive behaviour, which is
benecialtoscenerycapture.
18.3 Expert mode
TheExpertmodeunleashesthefullpotentialoftheNavigator250.Bankinganglesand
poweroutputaresignicantlyincreased,theaccelerationsensorisdeactivated,allowing
fullypilotcontrolledippingandrolling.
Thismodeisdesignedforpilotswhohavefullygainedexperienceandcondencewith
yingtheNavigator250.Itallowsfastpasses,loops,rolls,ipsatthepilot’sownability
sincecontrolfunctionssuchasauto-levellingarecompletelydisabled.
