Speed System
For better penetration in headwinds and improved glide performance in sinking air, crosswinds or
headwinds,youshouldyfasterthantrimspeedby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.To
accelerate,rstmakesurethatyouhavenobrakeapplied(removeanywrapsfromthebrakes)andtake
hold of the B risers, we recommend to use the wooden handles. Apply the speed bar smoothly and
progressivelytoavoidsuddenchangesofpitch/angleofattack(AofA)andtoallowthewingtoaccelerate
efciently.MaintainpressureontheBrisersanduseactivecontrolwithacombinationofthespeedsystem
andtheBrisersthroughturbulentair.OnlyreleasepressurefromtheBriserswhentheairissmooth.
Atfullspeed theZenois fastbuthas less inherentstability;only usemaximumspeed in verycalm air
conditionsandalwaysyactivelywiththeBrisers/speedbar.
Active Flying
Toreducethefrequencyofcollapsesinturbulentconditions,itisessentialtouseactiveying.Theaimof
activeyingistocontrolthepitchandinternalpressureofthewing.Thiscanbedonewiththebrakesor
theBrisers(seebelow),butinveryturbulentair,werecommendtoalwaysusethebrakes.
Inturbulentair,ywiththebrakesapplied(approx.20cm),thiswillgiveyouthenecessaryfeedbackwhich
isvitaltokeepthewingopen.Itisalsoimportanttolookatyourwingasthisgivesadirectindicationof
itsinternalpressureandlikelihoodofcollapse.Inputscanbesymmetricorasymmetric;youmayhaveto
applybothbrakesorjustonetomaintainequalpressureacrossthespan/chordofthewing.Avoidying
withcontinuous amounts ofdeep brakein rough air as youcould inadvertently stall the wing.Always
consideryourairspeed.
Active B Riser Control
Whenglidingattrimspeedorinacceleratedight,werecommendtopilotthewingwiththeBrisers.This
givesan improvedfeeland controlover the wingenabling youtoy activelywithout using thebrakes
(which causes drag and pitch movements). The direct feel allows you to stop collapses before they
happenandmaintainhigherspeedsandhigherlevelsofefciency.
ToywiththeBrisers,keepholdofyourbrakehandles(removeanywraps)andeitherrestyourhands
onortakeholdofthewoodenhandleslocatedontheBrisers.NowyouhavedirectcontroloftheAofA;
bypullingtheB risers downorrearwardsyouincreasethe AofA, releasingpressurereducesAofAand
returnsthewingtotrimspeed.WithBrisercontrolyoucanyactivelythroughturbulence,collapsescan
bestoppedoratleastreducedwithcorrectinputsduetothesuddenincreaseinAofA.Ifyoufeelthenose
ofthewingloseinternalpressure,oryouseeacreaseappearbetweentheAandBlineattachmentpoints
onthesailyoucanquicklyinputtheBriserstostopthecollapseoccurring.Theamountofpressureand
sizeoftheinputisdependentontheamountofturbulence,orlossofpressure,butalwaysavoidlongdeep
inputstoavoidinducinglargepitchmovementsorinadvertentstalls.
Duringaccelerated ight,the added controlof activeB riserying further increases the efciencyand
stabilityofthewing.WhilstacceleratedtheactofpullingtheBrisersisexactlythesameasreleasingthe
speedbar.Thistranslatestodirectcontrolofspeed,AofA,andinternalpressureinyourhands.Coupled
withactive speed barcontrol, adjustmentscanbe madewiththe Brisers to optimiseyour speed and
internalpressurethroughturbulencehelpingyoutomaintainahigheraveragespeedwhilstreducingthe
likelihoodofunexpectedcollapses.Whenpushingthebar,iftheairbecomesslightlyturbulentapplysome
pressuretotheBrisers,whentheairbecomeslessturbulentagainyoucanreduce(orrelease)pressure
ontheBrisersforextraspeed.Flyingfastandefcientlyinnormalairrequiresconstantattentiontothe
wing,itisnecessary to combineBriserinputs and speedbaradjustmentstokeep thewingopenand
pressured.
Thiscontrolmethodissuitableforglidingingood‘normal’airwithouthugelevelsofturbulence,itdoesnot
replaceproperactiveyingwiththebrakesinstrongturbulentconditions.Ifyouareunsureabouttheair
returntheglidertotrimspeed,releasetheBrisersandytheglideractivelywiththebrakes.
Big Ears
Topullbigears,keepholdofyourbrakehandlesandtaketheoutermostA-line(AR3)oneachside,then
pulloutand down(preferablyone at atime)until thewingtipsfold under. Thesizeof thebigears can
beadjustedbypullingmoreline,orreachinghigheruptheline.Oncethebigearsareengagedyoucan
furtherincreasethesinkratebyusingtheacceleratorsystem.FordirectionalcontrolwhileusingtheBig
Ears,useweightshift.
IMPORTANT
No pilot and no
glider are immune to
collapses, however
active ying reduces
the tendency to
collapse. When
the conditions are
turbulent, be more
active and anticipate
the movements of
the wing. Always be
aware of your altitude
and do not over-react.
IMPORTANT
Always keep hold of
your brakes. Do not y
in turbulent conditions
DO NOT perform spiral
dives with the Big Ears
engaged.
IMPORTANT
Whilst accelerated DO
NOT use your brakes
to y actively in
turbulent air, doing so
will actually make the
wing more prone to
collapse.
IMPORTANT
Regulate your speed
depending on the local
airmass. If it becomes
turbulent, release the
speed system and
y actively with your
brakes or B risers.
