12.14. LevelOffset
Thisfunctionisusedtooffsettheabsoluteangleerrorcausedbyinstallation.Suchdeviationmayprobablymake
theplanedropdownorupwhenoperatinginselfbalancemode.Youhavetoperformaleveloffsetafter
installationtomaketheplanemaintainlevelflight.Thereare2waystoperformaleveloffset: 

 AutomaticCalibration 
 Step1  Turnonthetransmitterandpowerontheplane,waituntiltheinitializationisdone.
 Step2  SwitchthecontrollertoSelfbalancemode.
 Step3  Puttheplanetoitsattitudeforlevelflightontheground(Usuallytheplaneshouldbeputwitha
smallangleofattack,whichisthemostappropriateattitudeforlevelflight).Clickthe“LevelOffset>
Automatic”menuintheprogramcardorthe“AutoLevelCalibration”buttoninthePCconfigtooltostart
thecalibration.Whilecalibrating,theLEDwillkeepblinkingYELLOWrapidlyforabout3seconds,don’t
movetheplaneuntilthecalibrationisdone.Calibrationmightfailiftheangleislargerthan ±20°in
eitherrollorpitchaxis.TheLEDwillblinkREDrapidlyinthecaseofacalibrationfailure.Ifit
happens,youneedareinstallation!
 Step4  It’sreadytoflyaftercalibration.

  ManualOffset 
Amanualoffsetallowsyoumakeafurtheradjustmentfortheinstallationdeviations.The
valuesareadjustablewithin ±20°inbothrollandpitchaxes.Pleasenotethatthereis
nodirectlinkbetweentherealmovingdirectionoftheservosandthepositiveor
negativesignofthevalues,becauseitdependsonwhichinstallationorientationor
gyrodirectionyouareusing.Forexample,iftheplanekeepsdroppingdowninselfbalancemodebefore
offsetting,youmightincreaseordecreasethevalueforpitchaxistomaketheelevatorsurfacealittleupperthan
before,untilyougetacorrectlevelflight.Foreaseofobservation,youmightneedtotemporarilyincreasethe
gainorgainratioforselfbalancemodebeforechangingthevalues,andrestoreitafterfinishingtheadjustment.

Inordertomakeabackuporsharingofthesettings,youcansave5copiesofthedataintotheinternalmemory
