plans several thousand pre-1941 designs Ive tried eliminate onerous tasks scratch building will try show few pet tricks construction notes Lets get started July1975 39 General As see model uses lot 3/16 x 3/16 spruce Get 48 lengths substitute balsa hobby shop can get spruce Sig should stock anyway Youll need several sheets 3/32 C-grain sheet balsa thats speckly kind 3/16 sheet can scrap box pieces short just sure grain runs drawn Try get celluloid windows butyrate sheet will work see-through look old fashioned Construction RC isl can make guy emotional Below radio just like installationstanks batteries two-channel brick etc Area 660 sq Fuselage Cut out formers respective sizes plywood quick way trace parts onto thin typing paper spray 3M Spray Contact Cement stick place Cut out part peel paper off Simple Drill holes nose form er dowels before assembly Mark drill engine mount 4x40 blind nuts Tatone tank mount will run 19 about 1 2 minutes plenty time get thermal activity prefer Sullivan tank will fit windshield area Just run tubes out side through celluloid Next lay sheet Saran Wrap 1-landi Wrap etc over plans use wax paper weakens glue joints Lay side fuselage down using ali phatic resin Tite Bond orSig Bond Allow dry least hour remove pins will way lay some small pieces Handi Wrap over structure areas might have trouble reaching knife blade separating halves later Build second side over first just similar possible Allow overnight dry separate halves using kitchen knife gently popping apart halves Now comes part everyone afraid Well make simple youll never dread frame fuselage again Fit bulk heads B C respective notches trim needed cement Sig Bond quickly turn fuselage upside down wing rests flat building board pin place Use clothespins masking tape hold B C place Square up right angle triangle adjustable carpenters square Keep fuselage square both dimensions ad justing clothespins tape until have lined up Dont take off board yet First fit crosspieces 3/16 spruce complete everything back bulkhead C allow set up least 24 hours fuselage still board lo cate center line marking middle B C Lay straight edge yard stick etc over marks clothespin place should extend tail post position Pull sides together tail post centers straight edge Now glue clothespin together aft ends sides Now mark mid lines remaining crosspieces place Check again squares tape everything place now have square fuselage dimensionsthat wasnt hard Add 3/32 sheet sides use contact cement front sand bottom contours Place 1/16 plywood bottom using

Finish fuselage dowels etc landing gear commercial item dealer can order comes com plete threaded axle Sure beats bending 5/32 wire Installation RC gear used Nyrods simple easy prefer pushrods go
