andtouseaheatguntoremoveanywrinklesandre‐tightenthecovering.Itisbesttodothisnowwhiletheplane

isnotassembled,remembertonotletanyheatgetnearanypartslikethecanopyorcowlasthismaycause

damage.



Wealsorecommendthatyougooveralltheaccessiblejointswithcyanoglue.Wickglueintoareasofhighstress

aroundtheU/Cplateandmotorbox.



UseNutlockonallmetaltometaljoints.Evenifyouareusingelectricwithlowvibrationlevelsitwillmakesure

LandingGearAssembly



Tostopthefuselagegettingdamagedwhilethemodelisassembledwerecommendfittingthelandinggearfirst.



Pusheachaxlethroughthelargeholesandtightenupusing2spanners.



Placeacolletontheaxlefollowedbythewheel,thenanothercolletontheoutsideasperbelowdiagram.



Donottightenupthecolletsyetasthewheelneedstobefittedanequaldistancewithinthewheelpant.



TheU/Crakesforwardsousethecorrectwheelpantperside.Putnutlockontothe2xfactoryfittedblindnutsonthewheelpant



Fitovertheaxleandsecurewith2xcapheadbolts



Nowlineupthewheelinthecentreofthewheelpantopeningandtightenthecollets.Remembertousenutlockandtomakesurethewheelcan

movefreely.

RearStab

Removetheelevatorsandhingesfromtherearstabandplaceitintheopening.



Itisimportantthatcareistakenwhenaligningtherearstab.Measureeachsidetomakesurethatanequalamountshowsoneachside.

FittheCFwingtubeandlookingfromthefrontandbackcheckthattheelevatorplateisinhorizontalalignmenttotherearstab.Ifitisnotthentrim

theopeningsothatitisequal.

Fitthewingsandmeasurefromtheendofthewingtotheelevatorstabtomakesurethatbothsidesareequal



Glueing–Onceyouthinkyouarereadytoglue,measureagain.Werecommend2methodsforgluing.Eitherremovethecoveringontheareathatis

coveredbythefuselageandgluewithepoxyorleavethecoveringonandgluewiththincyno.Wickinginthinfirst,ifalargegapisvisiblethenuse

mediumorthick.Remembertowickinsmallamountsatatimekeepingtheplanelevel,thiswillensurethegluestayswhereitneedstobe.

 

Dependingonifyouarefitting1or2elevatorservo’syoumayneedtofittheelevatorjoiningbar.



Workouthowmuchofthejoinerbarneedtogointotheelevatorhalfbylayingthebaroverthehalvesandsettingthesamelengthastherearstab.

Openupthecoveringattheinsideofeachoftheelevatorhavesandmarktheareaofwoodthatneedstoberemoved.



Cuttheareaofwoodawaywithasharpknife



Testfitthejoinerbar

 

Cuttheareaforthejoinerbarontheotherelevatorhalf,irondownthecoveringandtestfit.

Gluethejoinerbarinto1oftheelevatorhalveswithepoxy.

Nowwecanhingeoneoftheelevatorswiththejoinerbargluedin.

Apply‘vaseline’tothehingepointonthehingesandusing30minuteepoxytogluetheseintotheboththestabandelevatorhalf.Wipeoffexcess

gluebeforeitsets.

Dryfittheotherelevatorhalfwiththehingesandmakesurethatbothhalvesaligntothestab.Trimwherethejoinerbarsitsifrequired.

Gluethehingesinbothstabandelevatoragainwith30minuteepoxy.Whilegluingusetapetokeepitinalignment
