

Duetothemodelspendingtimeindifferentclimateszonesfromthefactoryonitswaytoyou,someofthe

coveringmayhavewrinkles.Wehighlyrecommendthatyoutaketimetore‐sealallcoveringedgeswithaniron

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



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

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.
