An.important.part.of.preparing.the.aircraft.for.flight.
is.properly.balancing.the.model..This.is.especially.
important.when.various.engines.are.mounted.
Caution: Do not inadvertently
skip this step!
The.recommended.Center.of.Gravity.(CG).location.for.
the.F6F.Hellcat.is.5

".(134mm).behind.the.leading.
edge.of.the.wing.against.the.fuselage..Make.sure.the.
gear.is.retracted.when.checking.the.CG,.as.the.CG.
will.change.depending.on.the.gear.position..Make.
sure.the.aircraft.is.inverted.when.measuring.the.CG..
If.necessary,.move.the.battery.pack.or.add.weight.to.
either.the.nose.or.the.tail.until.the.correct.balance.
is.achieved..Stick-on.weights.are.available.at.your.
local.hobby.store.and.work.well.for.this.purpose.
Charge.both.the.transmitter.and.receiver.pack.for.your.
airplane..Use.the.recommended.charger.supplied.with.
your.particular.radio.system,.following.the.instructions.
provided.with.the.radio..In.most.cases,.the.radio.
should.be.charged.the.night.before.going.out.flying.
Check.the.radio.installation.and.make.sure.all.the.control.
surfaces.are.moving.correctly.(i.e..the.correct.direction.and.
with.the.recommended.throws)..Test.run.the.engine.and.
make.sure.it.transitions.smoothly.from.idle.to.full.throttle.
and.back..Also.ensure.the.engine.is.tuned.according.
to.the.manufacturer's.instructions,.and.it.will.run.
consistently.and.constantly.at.full.throttle.when.adjusted.
Check.all.the.control.horns,.servo.horns.and.
clevises.to.make.sure.they.are.secure.and.in.good.
condition..Replace.any.items.that.would.be.considered.
questionable..Failure.of.any.of.these.components.
in.flight.would.mean.the.loss.of.your.aircraft.
Before.each.flying.session,.range.check.your.radio..This.
is.accomplished.by.turning.on.your.transmitter.with.the.
antenna.collapsed..Turn.on.the.radio.in.your.airplane..With.
your.airplane.on.the.ground,.you.should.be.able.to.walk.
30.paces.away.from.your.airplane.and.still.have.complete.
control.of.all.functions..If.not,.don’t.attempt.to.fly!.Have.
your.radio.equipment.checked.out.by.the.manufacturer.
