Gyro Gain Trimmer Pot Description and Adjustment

The.“gain”.trimmer.pot.adjusts.the.gain.setting.value.of.the.piezo.gyro.used.to.aid.in.keeping.the.tail.of.the.
helicopter.straight.while.flying .

•. Pilots.interested.most.in.hovering-type.maneuvers.with.very.little.forward.flight.and.aerobatics.may.choose.to.

have.the.gain.set.as.high.as.possible.(without.making.the.tail.twitch.quickly.from.side.to.side),.keeping.the.tail.
of.the.helicopter.very.solid.during.flight ..Do.note,.however,.that.high.or.excessively.high.gyro.gain.settings.will.
result.in.accelerated.tail.motor.wear.and.reduced.life .

•. Pilots.interested.most.in.fast.forward.flight.and.aerobatics.may.prefer.a.somewhat.lower.gyro.gain.setting.that.

allows.for.more.control.of.the.tail.in.flight .

Note:.For.more.“locked-in”.tail.performance.all.around,.we.recommend.the.installation.of.an.optional.Heading.

Lock.type.gyro.as.outlined.in.the.“Optional.Heading.Lock.Gyro.Installation.and.Setup”.section.of.this.manual.found.

on.pages.40–47 .

•. To.increase.the.gyro.gain,.simply.turn.the.trimmer.pot.clockwise.(+) ..Dial.the.trimmer.pot.counterclockwise.(-).to.

decrease.gyro.gain ..The.gain.value.is.set.too.high.if.the.tail.of.the.helicopter.twitches.quickly.from.side.to.side ..
This.gain.value.can.also.be.set.too.low,.allowing.the.tail.of.the.helicopter.to.feel.“loose”.in.flight ..Take.your.time.
