
Beginassemblybybuildingthetworearframesoverthe

thesidesheetpartsusingformersF1A,F1B,F2andthe
3/16”plymotorplate.Takeespecialcaretogetthemotor

thegluetodry,andthenaddthepartsF3andF4,
completewiththetriangularreinforcingblocks.Bendup
anddrilltheduralc/sstruts,drillthestrutplates,andbolt
thestrutssecurelyinplace.Lockoffallthenutswitha

alignment,jointhefrontandrearfuselagehalves.

So,nowthatyouhavesomethingresemblingafuselage,
