IMPORTANT

In the unlikely

event of a brake line

snapping in ight, or

a handle becoming

detached, the glider

can be own by

gently pulling the rear

risers (C-risers) for

directional control.

Limitations

The LM7 has been designed as a high performance solo XC/competition wing and is for experienced

pilotsonly.Itisnotsuitableforbeginnerorintermediatepilots,aerobatics,trainingortandemights.To

TheLM7wascertiedwiththeuseofcollapselines,thereforeduringSIVcollapsesmustnotbeperformed

informationpleasecontactyourlocalOzonedealer.Ensurethatyoufullyunderstandthecorrectandsafe

useofthisequipmentbeforeattemptingSIV.

PREPARATION

IMPORTANT

Using the accelerator

decreases the angle

of attack and makes

the wing more prone

to collapse, therefore

using the accelerator

near the ground or in

turbulent conditions

should be avoided.

Accelerator System

Tosetuptheacceleratorsystem,rstroutethelinessuppliedwiththespeedsystemthroughtheharness.

Makesurethisisdonecorrectlyandthat thelinespassthroughallofthepulleys(checkyourharness

manualforinstructions).Attachthespeedsystemlinestotheacceleratorsystemontheriserswiththe

Brummelhooks.

Abasic set-up can be performed on the ground: ask a friend to pull the risers tight intotheir in-ight

positionwhilstyousitintheharnessontheground.Nowadjustthelengthsofthelinessothatthemain

barsitsjustbeneathyourseat.Youshouldbeabletohookyourheelintothelowerloopoftheaccelerator.

TheremustbeenoughslackinthespeedsystemtoensuretheArisersarenotinadvertentlypulledduring

normaltrimspeedight,butnotsolongthatitisimpossibletousethefullspeedrangeoftheglider.Fully

extendingthelowerloopofthespeedbarwillacceleratethewingtoapproximatelyhalfitsaccelerated

speedrange.Forfullspeed,hookyourheelsontotheupperbarandsmoothlyextendyourlegs,maximum

speed is when the pulleys on the risers overlap. Once set up, test the full range of the accelerator in

calmyingconditionsandensurethatbothrisersarepulledevenlyduringoperation.Fine-tuningcanbe

completedwhenyouarebackontheground.

Harness

Itisimportanttosetupyourharnesscorrectlybeforeyingthewing.Makesuretospendtimeadjusting

your harness’s different settings until you are completely comfortable. We recommend a chest strap

Topreparethewing,layitoutonthetopsurfaceandperformathoroughdailycheck.Youshouldinspect

BASIC FLIGHT TECHNIQUES

IMPORTANT

Never take off with

a glider that is not

fully inated or if you

are not in control of

the pitch/roll of your

wing.

Launching

Your LM7 will launch with either the forward or reverse technique. The wing should be laid out in a

pronouncedarc,withthecentreofthewinghigherthanthetips.

Forward Launch - Nil to Light winds

Whenthewindisfavourable,whilstgentlyholdingtheArisersmoveforwardpositively,yourlinesshould

becometightwithinoneortwostepsandtheLM7willimmediatelystarttoinate.Youshouldmaintain

aconstantpressureontherisersuntilthewingisoverhead.Donotpulldownorpushtherisersforward

excessively,ortheleadingedgewilldeformandpossiblycollapsemakingtaking-offmoredifcultand

potentiallydangerous.

Movesmoothlythroughouttheentirelaunch,thereisnoneedtorushorsnatchatit.Youshouldhave

plentyoftimetolookupandcheckyourcanopybeforecommittingyourself.Onceyouarehappythatthe

LM7isinatedcorrectly,acceleratesmoothlyoffthelaunch.

Reverse Launch - Light to Strong Winds

Layoutyourwingasyouwouldfortheforwardlaunch.However,thistimeturntofaceit,passingone

entiresetofrisersoveryourheadasyouturn.Nowyoucaninatethegliderwithyourbodyweightand

theA-risers.Oncethewingisoverhead,releasetherisers,brakegentlyifnecessary,turnandlaunch.

Instrongerwinds,bepreparedtotakeafewstepstowardsthegliderasitinates.Thiswilltakesomeof

theenergyoutoftheglideranditwillbelesslikelytooveryyou.Thisreverse-launchtechniquecanbe

usedinsurprisinglylightwindstoo.

Speed to Fly

Flyingattrimspeed(hands-up),theLM7willachieveits‘bestglide’speedforstillair.Youshouldyat

thisspeedwhenglidingdownwindorwhentheairisnotexcessivelysinking.Forbetterpenetrationin

headwindsandimprovedglideperformanceinsinkingair,crosswindsorheadwinds,youshouldyfaster

thantrimspeedusingtheacceleratorsystem.Usinguptohalfbardoesnotdegradetheglideangleor

stabilitysignicantlyandwillimproveyouryingperformance.Youwillreachthenextthermalfasterand

higher.AtfullspeedtheLM7isstable,howeverwerecommendthatyoudonotyatfullspeedcloseto

Westronglyadviseyoutokeepholdofyourbrakesatalltimesandtonotyinturbulentconditions.

IMPORTANT

Always keep hold of

your brakes. Do not y

in turbulent conditions

IMPORTANT

Never initiate a turn at

minimum speed (i.e.

with full brakes on) as

you could risk entering

a spin.

therefore they should

never be executed

CARE AND MAINTENANCE

Caring Tips

Carelessgroundhandlingdamagesmanyparagliders.Herearesomethingstoavoidinordertoprolong

thelifeofyouraircraft:

•DONOTdragyourwingalongthegroundoranyhardsurfaceasthisisguaranteedtocausedamageto

thesailcloth.Liftitupandcarryitclearoftheground.

•DONOTtrytoopenyourwinginstrongwindswithoutuntanglingthelinesrst-thisputsunnecessary

•DONOTwalkonthewingorlines.

•DONOTrepeatedlyinatethegliderandthenallowittocrashbackdown.Trytokeepthismovement

assmoothaspossiblebymovingtowardsthegliderasitcomesdown.

•DONOTslamyourgliderdownonthegroundleadingedgerst!Thisimpactputsgreatstrainonthe

wingandstitchingandcanevenexplodecells.

•FLYINGinsalty air, inareaswith abrasive surfaces(sand,rocks etc.) andgroundhandling in strong

windswillacceleratetheagingprocess.

•DONOTyintherainorexposethewingtomoisture.

•DONOTexposethewingtounnecessaryUVorhighlevelsofheat.Leavingthewingsittinginthesunor

allowingittogethot(e.ginthebackofacar)willsignicantlyincreasethechancesofprematureageing.

•Ifyouywithawrap,youshouldregularlyundothetwistingthatappearsonthemainbrakelines.By

twistingthelinebecomeshorterandyoucanendupwithaconstanttensiononthetrailingedge.

•Changeyourmainbrakelinesiftheyaredamaged.

•Whengroundhandlingbecarefultonotsawthebrakelinesagainsttherisersormainlines.Theabrasion

causedbyasawingmotioncandamagethemainlinesandtherisers.Ifyounoticeanysignsofabrasion,

especially to the lines, make sure to replace them. It is important to modify your groundhandling

techniquetostopanyfuturedamage.

•Yourwinghasanopeningonthewingtipscalledthe‘Butthole’.TheButtholemakesiteasytoempty

anysand,leaves,rocks,mobilephonesetcthatmayhaveaccumulatedinthewing.

ItisrecommendedthatyouregularlyCHECKyourwing,especiallyafteraheavyperiodofuse,afteran

incidentorafteralongperiodofstorage.

IMPORTANT

Only a few cms of

input from your

brakes can maintain

your wing in the stall.

Always release your

wraps if you have

taken them!

IMPORTANT

A bad preparation

on launch, aerobatic

ying, ying a wing of

too high a level or in

conditions too strong

for your ability, are

the main causes of

cravats.

IMPORTANT

Never y in the rain or

with a wet glider.
