The offset settings:
Theoffsetpointisthepositionofthemasterencoderfromwhichthesalvechannelisadded.Ifthevalue0%isset,the
offsetpointisinthecentrepositionofthemasterencoder.Ifthemasterencoderisthendeectedfromthecentreto
theleftandright,theslaveservowillalsodeecttotheleftandrightifthedefectionvaluesaresetaccordingly.
Therealsoistheoptionofdeectingtheoffsetpoint.Thisisrecommendedwhentheslaveservoistodeectinonly
one direction and the master encoder is a „non-self-neutralising encoder“, such as a rotary encoder or the throttle/
pitch stick.
Practical example:
Ifa glidermodelhas spoilerapsin thewings,they areusu-
ally controlled via the throttle stick (see schematic illustration in
sketch A and B).
With the stick in front (top gure, sketchA), the spoiler aps
are retracted. If the control stick is pulled back to the body, the
spoilerapsextend.Inmostmodels,anelevatordeectionmust
bemixedinforthemodeltoyonstraight.
Withoutoffsetsetting(sketchA),theelevatorwouldbedeected
downandupaccordingtothevaluessetwiththeapsretracted
and extended.
With half-extended spoiler aps, the elevator is in the centre
position since the throttle stick is also in the centre position (see
middle drawing, sketch A).
Use the offset setting (sketch B) to move the throttle stick all the
way to the front and to change the offset value so that the eleva-
tor is in the centre position again (see top drawing in sketch B).
If the throttle stick is now moved back to the centre position, the
requiredelevatordeectionismixedin.
Since the max. elevator addition is already reached
at the centre position of the throttle stick, the elevator
deectionwillnolongerchangeifthethrottlestickis
taken back farther.
 Forbetterillustration,themixed-inelevatordeection
inthedrawingsingure47wasillustratedmuchlarger
than it actually has to be.
