1.Introduction
CongratulationsonthepurchaseoftheHawkerHunter,producedbyDerJetModelCompany,TAIWAN!
This1/6scalelegendaryjetwasdevelopedonthebaseofaWorldMastersmodeldevelopedandflownby
three‐timesvicechampionRetoSennofSwitzerland.Thus,youdidnotonlybuyamagnificentflyingplane,
thisARFkitisdesignedtoallowparticipationincompetitionssuchasthe13,5kgclassattheJetWorld
Mastersorothers.TheseoutlineshavebeenoriginatedbyFlightfactory.chGmbHonthebaseofthefirst
Hunterkits.Subsequently,minorchanges/improvementsinthemanufacturingofthekitarenotincluded.
(Thesebuildingguidelinesareinnocasemeanttoguaranteeanycoverofdamageormalfunctioncaused
bynegligence,misuse,accident,unauthorizedrepairormodificationasthefinalusecannotbecontrolled

RCpowersupply:WerecommendusingadualpowersupplysystemsuchasPowerBoxSystemsInthefirst
threeHunters,weusedoncePowerBoxEvolution(withexternaldoorsequencer)andfor
convenience,twicePowerBoxCockpitSRS(withintegrateddoorsequenceranddual
satellitereception)poweredbyLiPo7,4Vwith2x2800mAhcapacityorLiFe6,6Vand2x
3200mAhcapacity.
Turbine: ThelightandyetsolidconstructionoftheDerJetModelHunterallowsforawiderangeof
turbines.Flyingwithwith12‐14Nofthrustpowerissufficientforflightperformance.Yet,
itallowssafetake‐offsfromeverysurfaceatthecostofslightlyhigherspeedinthefinal
landingapproach.TheuseofaJetCatP90RXi(10,5kgthrust)byoneSwisspilotallowed
bothcomfortabletake‐offs(40monhardsurfacerunway)andsmoothrealisticflyingwith
reasonablyshortlandings.

4.Optionalaccessories:ToupgradeyourDerJetModelHawkerHuntertoafull‐scalejet,theoptionalparts
arehighlyrecommendedbothforstaticandflightdisplayincludingunderwingtanksanddetailedkitofcannon
blastdeflector,antenna.
5.Mainwingcompletion
Buildingthewingsisstraightforwardanddoesnottakemuchtime.Ifyoudobothwingsatthesametime,just
makesurethatonepairofservosisoppositehandedasshowninthepictures.Startwiththeinstallationofthe
servos,whichfitperfectlyintothefactory‐installedservomounts.


Justusetheservogrommetsandtheservocoverwillkeeptheservowellfixedandinplace.Watchoutforthe
servoleadtomovefreeandpreventitfrombeingscratchedbysharpfibreedges.Shouldyouwishtoinstall
functionalpositionlights,youhavetodrillaholeof4mmfromthelightlocationtowardstheaileronservomount
throughwoodenformers.Iglueda4mmdrillintoanaluminiumtube5x4mmtoallowdrillingtothedistance.
Oncedrilled,pre‐installthelightwiresorfinishinstallationofthelightsbeforemountingtheaileronservo.







Runtheservoandlightwireswiththefactory‐installedwhitelinetowardstheinnersideofthewinganddothe
samewiththeflapservo.Makesuretheneutralpositionoftheservohorniscorrectbeforefinallypositioningthe
twoservos.Startnowwiththeflapanddrawthepositionofthethreeflaphingesfromthewingtotheflap.


Carefullydrilla5mmholeintotheflaps,startingwithsmallerdrillsandsmartlyincreasingthediameter.Rougher
methodsmightresultintodamagedsurfaceofthepaintedflap.Repeatthisdrillingtoopentheholesforthe
hingesonthewing,positioningtheholeasfarawayaspossiblefromtheflaptoallowfreemovement.





Gluethethreehingesintotheflapafterhavingcontrolledeasyandsmoothtravel,usinga24hrsgluesuchasUHU
Endfest300andthickeningmaterialsuchasthixotropicpowder.Youmaywanttoshortenthehingestofitthe
holesoneithersideoftheflapsandwingasshowninthepicture.
Addonetinydropofoilintothehingepointtoavoidbeinggluedtogether.Makesuretheoildoesnotspillover
thehingewhereitshouldbeglued!Oncedry,gluetheothersideofthehingesintothewing,usingthesameglue
andfixitwellduringthedryingprocess.



Once dry, mark the positions for the control horns for both the aileron and flap using masking tape.



Placethecontrolhornfortheaileronsuchasthepilotholeisrightoverthemovinglineoftheflex‐strapofthe
aileron,allowingtheservototravelatthesameforceupanddown.
Theflapcontrolhorncanbeinstalledslightlytotherearedgeofthewing,allowinglargertravelandthusmore
leveragedforcefromtheflapservo.Carefullyopennowtherequiredslotlengthsforthecontrolhornsusinga
dremelcuttingdiscorothertoolsyouarefamiliarwith.



Nowdrilla3mmhole(orsmallerifusingaclevis)intothehornsandroughenthelowerpartwheretheywillbe
gluedintothecontrolsurface.Applysufficientamountofglueintotheslotsaswellasonthehornsforperfectly
solidfit.Fixthecontrolhornsduringdrying.
Oncethegluehasfullycured,installthepushrodsandre‐mounttheservohatchcoverssuchastheservohorns
canmovefreeintothecoverslots.




Itisrecommendedtomountthemainlandinggearanditsdoorsintwosteps.Asthemechanicsandlegsaswellas
thewheelsarefactory‐assembled,thefirststepisdonequickly.
Beforescrewingthemechanicsinplace,fixthe3mm‐tubes(twodifferentcolorsofyourchoicefromthehardware
pack)overthesmallfittings.Runthetubesintothewingandsmoothlybackthroughtheholesinthewooden
formersandmakesuretheymovefreelyanddonotbend.Leaveenoughlengthsofarandcutitlatertoyour
preferredlength.InstallnowthemechanicswitheitherwoodscrewsorwithM4screwsandself‐tappingnuts
underneaththewoodensupports.Bothhavebeentestedinpracticeandthesimplewoodscrewssustainwell
evenonroughsurfaces.Tracknowthewheelangletemporarilyuntilyouaredonewiththefinalassemblyanddo
aroll‐out.


Markthepositionofthescrewholesoverthemaingeardoorsusingthemaskingtape.


6.Horizontalstabilizerassembly
Asforthemainwings,finishingthestabiseveneasiertodoastheycomewithfactory‐installedservomountsas
wellastheelevatorfixedwithflex‐strips.Thatleavesyouwiththechoiceofservostoinstallandgluingthecontrol
horns.Thishasbeenexplainedinthemainwingsectionwhichyoumaysimply“copyandpaste”thisforthestab.
Thedesignoftheservomountsleavesawiderangeofsuitableservosatyourdiscretion.TheFutabaBLS153
shouldprovidehighsecurityandenoughpower.Werecommendtochooseservoswithatleastapprox.5kg/cmof
torqueandpreferablymetalgears.Iusedadouble‐sidedfoamytapetocovertheservosideandtouchingthe
hatchcover,whichadditionallyholdstheservoinplaceoncethecoverisfirmlyscrewedinplace.









Sosimplyassemblethetwostabswiththeincludedsolidcarbonstabsandjustdrillasmall2mmholeineachof
thelowersidepartsofthestabsandusea2,2mmself‐tappingscrewtoholdtheminplace.



7.Rudderassembly
Thekitagainleavesyouwiththechoiceofinstallingservohorn,pushrodandcontrolhornoutsidesuchasforthe
aileronsandelevators,whichisstraightforward.Astheverticalfinprovidessufficientspacetomountastandard
sizedservoandletthepushrodruninside,itmayincreaseyourappetiteforamorescale‐likesolutionwithbarely
seeinganymechanics.Inanycase,therudderisfixedwithtwohinges.Wellglued,theyhaveprovedenough
strengthtoresistanyrudderforce.Irecommendtofirstgluethehingesintotherudder.Whenplacingtheminto
theexistingholes,watchthehingepointstobeinlineandasfarinsoyoubendata90°angleandagainparallelto
eachother.
