The Anatomy of a XuGong

The Foldable Arms, Motor Mounts, and Motors

Thefoldablearms,milledoutofasolidplateof5mmAluminium,allowtheXuGongtocollapseto

asizewhichfitseasilyintotheaverageShoeBox/HandBag/BackPack,etc.

Whetherthelong,orshortarmversionisbuilt,thepivotpointsallowthefourmotorstopivotinto

thecenteroftheframeforstorageandtransport.Whileinthisposition,thepropbladesare

mucheasiertoprotectfromdamagethantheyareonamoretraditionalquadcopter.

The Anti-Jello Plate

TheAntiJelloplateconsistsofanFR4plate,laidoutwithPCBtraces,whichroutethepower

betweenthebattery,andthefourESCs.

Itincludesaselectionofholesforsiliconedampers,thenumberofwhich,andthedurometer

(hardness)ofwhich,determinethetradeoffbetweenvideoquality,andaerobaticflight

characteristics.

Twokindsofdampersareavailable,theblackonesincludedwiththeproduct,whicharegoodfor

slowflyingphoto/videowork,andsomeharderreddampers,formoreaggressiveflying.

Thereddampershaveaslightlydifferenttooling,toleavemorematerialinthecenter.

The Frame Assembly

TheFrame,constructedmainlyofaverysturdyblackFR4material,holds(andprotects)the

battery,andalloftheelectronics.Theflightcontrollersitsinaprotectedboxinthecenterofthe

frame.TheA/VTx,andUHFRxcanoptionallybeplacedintherecesseseachsideoftheframe,

keepingthemprotectedagainstcrashdamage.

AnalternativeframeassemblywillbemadeavailableinearlyJanuary2014,whichwillbemade

ofcarbonfibre,withlightweightanodizedaluminiumnutsandscrews.

ThisversionworkswellfortwotypesofQuadflyers,thelongrangefanatic,whowantstoshed

everygramfromtheweightofthequad,andtheposer:),whojustwantsaquadtolook

fantastic.

The GoPro Camera Assembly

TheGoProcameraassemblyincludesapaddedsupportforaGoPro3(anyedition),anoptional

supportforanSDcamera(FatSharkCMOS,with‘GoProequivalent’Lens,highlyreommended).

ForthestandardversionoftheXuGong,asimpletiltonlygimbalusingaHitecHS65MGservo

(orsimilar)issupported.Thisisafairlyrobustmechanism,whichworkswellforaquadwhich

willbecrammedintoabackpackduringtravel.

The‘HB’versionofthisservoworksalso,butthegearsareabitfragileforthisapplication.

AbrushlessgimbalisunderdevelopmentfortheXuGong,andwillbeavailableinearly2014.

Several3rdpartybrushlessgimbalshavebeensuccessfullyusedontheXuGong,includingthe

Tarot,whichwithafewsimplemodificationscanbemountedontheXuGong’sfrontbulkhead.

Building the XuGong... Component Selection:

Thereareahugenumberofdifferentcomponentsavailabletobuildmulticoptersthesedays.The

costofthesecomponents,alongwiththeirquality,andcompatibility,varieswidely.

Thecomponentselectionsbelowarebaseduponourexperiencetodate,andwillresultina

successfulfoldablequadcopterbuild.

Flight Controller

MostoftheXuGongprototypesbuiltbytheImmersionRCteamhaveusedvariousversionsof

theDJINazaFlightcontroller.

Thisexperiencewillbereflectedinthisbuildlog,itwillbetheflightcontrollerusedduringthe

build.

TheNazaMLiteis,insomeways,moresuitablethanthenewerV2,duetoitsmuchsmaller

(andthuseasiertomount)LED/Powerunit.

Ofcourse,anyflightcontrollerdesignedtoflyquads,assumingreasonablephysicalsize,willdo

justfineasareplacementfortheNaza.

ForusewiththeOpenPilot,andsimilarFCs,astandardpatternof4holesisprovidedonthe

bottomplateoftheframe.

Motors

Asfortheflightcontroller,mostoftheXuGongprototypeshaveusedthestockDJImotors(DJI

2212/920kV).Thesearegenerallypricedfairlyreasonably,andfittheframearmsnicely.

Theyarealsocompatiblewitheitherthe8”DJIpropsusedonthesmallerversionoftheXuGong,

theXuGong8,andthe10”(1038)propsusedontheXuGong10.

Props

OneofthemostcommoncausesforcrashingduringtheXuGongdevelopmentwasdueto

propsbreakinginflight.Theearlier8”DJIpropsweregenerallytheculprit.

Graupner8”carbonfibrepropsdoworkasreasonablereplacements,butrequireasmall

amountofdrilling/filingtoallowthemtofitontheshaftsofthestockDJImotors.

Forthe10”versionoftheXuGong,thenewer1038propsfromDJIworkverynicely,andareyet

tofailforusinflight.

Tip:EventhoughtheXuGongisdesignedtoreducethetransmissionofvibrationtothe

camera,wellbalancedpropsarestillagoodidea.

Battery

SeveralbatteriesarecompatiblewiththeXuGong,andshouldbeselectedbaseduponthekind

offlightcharacteristicsrequired.Abatterybox30mmheight,with2.4mmrequiredforthe

retainingringoftherubberfeetmeansthata28mmtallbatteryfitscomfortably,butnothingtaller.

RememberthatthebatteryplaysabigpartinthedeterminationoftheCenterofGravityofthe

XuGong.Aheaviercamera,orabrushlesscameragimbal,canbecompensatedforbyaheavier

battery.Inaddition,anoseheavyXuGongcanbebalancedbyslidingthebatteryrearwardsin

thebatterybay,andpaddingthefrontofitwithasmallblockoffoam.

Forpureflighttime,theZippyCompact4000,4s,25C,isagoodchoice(HobbyKingPart

NumberZC.4000.4S.25).ThispackisusedonmostoftheImmersionRCprototypeXuGongs.

A/V Transmitter

Thiswillbealittlepredictable,butwedohighlyrecommendanImmersionRCproductfortheA/V

transmitter.Forlicensefreeuse,on5.8GHz,the25mW5.8GHzTxisagoodchoice,andwill

complywithCEstandardsforuseinEurope.

Forlongerranageuse,orwherearadiolicenseisavailable,thepopular600mW5.8GHz

transmitterisalsoaverygoodchoice.

ThetopandbottomframeplatesforthestockXuGongaredesignedtofitthetransmitter

betweenthem,protectingitfromdamagecausedbymost‘hardlangings’.

Asmallpieceof3MVHBtapekeepsthetransmitterfirmlyattachedtothesideofthequad.

A/V Transmitter Antenna

ThebottomplateoftheXuGonghasa‘hook’designedtomountoneofour5.8GHzSpiroNET

omnidirectionalantennas.Thisispositionedsoastokeeptheantennabelowthecraft,inclear

viewofthegroundbasedreceiver,andthecorrectdistancefromtheA/VTxforthestandard

cablelength.

FPV Camera

EventhoughthevideooutputofthegimbalmountedGoPromaybeusedasanFPVcamera,it

isnotreallyrecommended.GoProcamerashavebeenknowntoshutdown,losingtheirvideo

feed,forseveralreasons(toohot,toocold,deadbattery,..justbecauseitisthethirdSundayof

themonth…).

ToavoidthestressofhavingtousetheFlightController’s‘ReturnHome’functiontorecovera

‘blind’quadcoper,asecondaryFPVcameraishighlyrecommended.

ThegimbalwasdesignedforusewiththeFatSharkCMOScamera.Lightweight,andwithvery

goodperformanceindifficultlightingsituations.

AwideanglelenseisrecommendedinordertolettheCMOScameraseethesame(orsimilar)

FPVastheGoPro.ThismakesframingshotswhilefilmingwiththeGoPromucheasier.

Radio Control system

Continuingonthepredictabletheme,wehighlyrecommendtheImmersionRCEzUHFreceivers

foruseinthecontroloftheXuGong.ThesecanbeeasilyprogrammedtoemitaPPMstream

fromoneoftheservooutputs,whichiscompatiblewiththePPMmodeoftheNazacontroller.

Thisgreatlysimplifieswiring,andenableseventhe4channelEzUHFreceivertosupplythe5

channelsrequiredtoflythequad,plusadditionalchannelsforgimbal(andother)control.

AnyoftheEzUHFreceivers,canbeusedwiththeXuGong,thislistcurrentlyincludesthe4

channel,8channel‘lite’,and8channeldiversity.

Attheotherendoftheradiolink,thereareseveralradioscompatiblewiththeEzUHF.Our

currentfavouriteistheFrSKYTaranis,withournewJREzUHFModulepluggedintheback.

WiththeEzUHF,evenwiththe4channelunit,radiocontrolrangewillexceedtherange

achievablebythequaditself.

FortheEzUHFRxAntenna,afull½wavedipoleishighlyrecommendedifrangeofmorethana

fewkilometersisrequired.

Thisantennacanbeconstructedusingthemonopoleantennaswhichareshippedstockwiththe

EzUHFReceivers.Takealengthofthecablecommonlyusedforbicyclebrakecables,the

samelengthasthemonopole,andsolderittothesideofthemonopoleSMAconnector.The

flexiblenatureofthiscablewillallowtheantennatodeformduringtakeoffandlanding,andfold

outtocreateasoliddipoleduringflight.

Mountthereceiveronthebackofthequadcopter,nearthe‘tail’,withthedipolemounted

verticallybehindit.

Building the XuGong... Basic Concepts:

Concept #1: Introducing the IRC T-Nut

TheIRCTNutisauniquedesignwhichallowsverystrongjointsbetweenFR4plates,while

captivatingthenylocnutduringassembly.

Usingtheseiseasy,justinsertthenylocnutintotheplasticpart,andpushthetwointothe

TSlot.ThepartswillberetainedtoallowthesecondFR4platetobemated,andthescrew

inserted.

Tip:ifyouhavedifficultiestoinsertthenylocnutandtheplasticpartintheTSlot,firstsqueeze

thelowerpartinandtwistthetopintheholeinsteadofinsertingitfromtheside

Concept #2: Anti-Jello Dampers
