. . . .Step 1
Install.the.recommended.servo.hardware.(grommets.and.
eyelets).supplied.with.the.servo..Install.a.long.half.servo.
arm.(JRPA212).onto.the.servo..Connect.a.24".Servo.
Lead.Extension.(JRPA212).to.the.servo.lead..Secure.the.
connectors.by.tying.them.in.a.knot,.using.dental.floss,.
or.by.using.a.commercially.available.connector.clamp.to.
prevent.the.servo.leads.from.becoming.disconnected.
Note:.Always.secure.the.servo.connector.and.
servo.extension.together.to.prevent.the.wires.
from.becoming.unplugged.inside.the.wing.
   
. . . .Step 2
Position.the.servo.onto.the.hatch.so.the.servo.arm.is.
centered.in.the.notch..Also.ensure.the.servo.arm.does.not.
extend.past.the.edge.of.the.servo.hatch..Once.satisfied,.
mark.the.location.for.the.servo.mounting.blocks.
