THIS DESIGN started life 14-gram Bostonian semiscale Lacey M- 10 idea metamorphosis came cousin Tom Schmitt still HiLine Ltd time told motor used HiLines Mini-6 unit available gearing HiLine motor now available Micro-4 Don Srull Tom said built flown several small models successfully using little gem motor two 50-mAh batteries entire power train weighed 20 grams Id pretty well blocked out Lacey M-10 design quick calculation showed enlarging 48-sq-in Bostonian 12 times could convert 70 sq-in mini-Electric So after quick trip local photocopy shop design time motor Construction fun flyer easy build construction conventional caveat though Light weight allimportant Choose wood very selectively use much adhesive necessary dope structures covering lightly possible Wing I generally build structure first builder can choose between sliced sheet solid ribs chose sliced ribs because thought result would lighter Now Im sure since felt necessary use auxiliary spar support front upper cap strips either case choose light hut firm quarter-grained wood 6- 8-lb density Cut spars leading edges trailing edges firm straight grained wood 8- 10-lb density Build both panels flat plan Join center section Add gussets sand wing lightly over Note wing-attach screw location boxed small rectangles 1/16 balsa prevents having chase small 4-40 screw over inside covered wing did Tail surfaces too built flat plan recommend building fin rudder unit separating after have joined soft copper wire hinges Sand tail surfaces lightly over Fuselage deviation conventional box frame constructiontwo side frames joined cross membersis two side frames dont match cabin area full-scale prototype asymmetry result passengers door being right side looking forward pilots door left Cut longerons firm straight grained wood 8- 10-lb density Somewhat lighter wood acceptable uprights cross members diagonals Note top longerons have severe bend can achieved help either ammonia jet steam Since forward lower longerons 70
