During.operation,.permanent.radio.interference.prevails..The.RC.EYE.650.starts.an.emergency.landing.independently..The.red.and.green.

low voltage Monitoring
The battery voltage is permanently monitored. If a certain battery voltage is exceeded (threshold approx. 9.4 V), the red LED (LD2) starts to
flash.quickly..The.green.LED.(LD1).is.permanently.lit..This.indicator.can.only.be.reset.by.disconnecting.the.flight.battery..If.the.red.LED.(LD2).
flashes,.you.should.carry.out.a.landing.as.quickly.as.possible.and.adjust.the.flight.operation.
If the RC EYE 650 is connected to a non-fully charged battery, this can also lead to undervoltage detection. In this case, fully charge
the flight battery first of all and then try the take-off once again.

general handling
An.RC.EYE.650.is.essentially.equipped.with.the.handling.of.a.normal.helicopter..The.differences,.however,.are.in.the.detail..For.helicopters,.
the.torque.balance.is.stabilised.by.special.gyros.(in.the.yaw.function)..For.this,.there.are.two.different.systems:."Normal.gyros".or.gyros.with.
the."heading-hold".function.
Normal.gyros.stabilise.(cushion).the.tail.propeller.against.tipping.motions.which.are.caused.by.the.pilots.(driving.speed.and/or.nick.changes.
and/or.external.influences.(e.g..side.wind)..A.gyro.with."heading-hold".function.has.a."holding.action".against.these.tipping.motions..Both.
systems.respond.to.a.control.command.–.e.g.."yaw.to.the.left".and.subsequent.neutral.positioning.with.the.immediate.stopping.of.the.tipping.
motion.
In.your.RC.EYE.650.–.unlike.in.standard.helicopters.–.there.are.three.gyros.installed.for.the.yaw,.nick.and.roll.functions..The.installed.gyros.
are.–.in.comparison.with.standard.gyros.–.neither.to.be.described.as."normal.gyros".nor.with."heading-hold".function.
The.gyros.in.the.RC.EYE.650.are.linked.together.so.that.after.the.end.of.a.control.command.the.RC.EYE.650.always.attempts.to.reach.
neutral.position.(hovering.flight)..Of.course,.how.well.this.works.depends.on.the.space.available,.the.flight.speed.and/or.the.prevailing.flight.
condition,.the.trim.values.of.the.RC.EYE.650.and.external.flight.conditions.e.g..wind.
starting the Motor
Before switching the transmitter on, set the throttle stick to "motors off" and all trim levers / trim sliding controllers of
the pilot stick to the neutral position. otherwise, the rC eye 650 may not recognise the transmitter after the battery is
connected.
