Monty Newman president Hartford Engineering Havre de Grace Md manufactured fiberglass mold mold have built four airplanes fly basically very much alike weight ranges have 7 lbs 3 oz 9 lbs complete ready fly out fuel Attention drawn small insig nificant looking diagram Fig 1 will great value people decide build F-S will also great use anyone building RC kit original design size object bolt wing place fuse lage locate fuselage wing stand until leveling dial indicator reads zero shown indicator should sitting top /2 wide template made balsa wood top template should parallel center line wing rib same true stab However stab flat template will required next step will locate stab template top finished stab has inserted through fuselage sides ready glued place Move leveling indicator top stab template adjust approximately Y4degree positive incidence point can check horizontal positioning stab shim place small balsa wedges Tack glue stab place 5-minute epoxy Last operation locate engine align ment Use flat maple strip X 12 long Cut hole through center /8 thick surface install spinner backplate shaft bolt maple strip position Rubber-band engine approximate position time move leveling device maple strip shown Fig should read 90 degrees achieve zero thrust line reference 8 Model Aviation wing Double check surfaces readings maintain same previously described drill engine mounting holes method will take guesswork out locating stab relation wing engine positioning have found due curvature fuselage easy fooled final position ing after final building heart break learn have made mistake Before starting fabrication model would suggest details like motor mounts i/s plywood firewall bulkhead ood main landing gear plat forms 3/16 plywood should fabri cated first items will help learn ing curve plans will insure proper cut outs details building progresses would also recom mend using epoxy holding heavily loaded items like motor mounts fire wall etc water base glues internal structures Skin butt joints can joined Hot Stuff smooth sanded outer surfaces sure surfaces perfectly matched because Hot Stuff will bridge small gap like other glues concerned about seams opening later can add strip tissue paper inside surface skins before joining structures Use favorite glue areas will fuel-soaked may want use light-weight glass cloth resin cutting cloth areas allow approximately /4 mismatch have found experience once have small patch located well advised leave alone Also small spot epoxy 5-minute will hold cloth con tour can brush resin Wing Construction wing has shown plans using build-up construc tion technique decide cup tea please use Adjusto-Jig equivalent insured straight true wing assembly Dihedral approx imately inch under tip has successful As can observe plans wheel retract mech anism plate well supported wing rough landings flying grass fields will little worry Ailerons barn door type method chosen order maintain horizontal stability very low speeds guess whatit really works will find F-S will land very low speeds approximately 10 degrees nose high attitude Barn doors take some worry out cross wind landings say nothing stopping money going through four-point rolls Cuban eights etc will observe Rhom-Products torque tubes used aileron hinges order maintain true hinge line small length tubing same diameter used outboard ends ailerons additional bushing design gives trouble-free operation Take care make sure three guide bushings torque tubes perfectly line wing panel Cut out ailerons after top wing has sheeted sanded Stabilizer Making stab very sim ilar wing assembly technique Cut ribs sandlocate wing jig cutting tool cut holes locating wires Ad just station locators install ribs Adjusto-Jig equivalent Locate trail ing edge
