喷气式飞机BD5 制作指南

Designed and Drawn by: Tony Audsley (Lockey)Suggested build specs:Material: 6mm Depron or MPF (approx one and a half full sheets) 1000 x 700 sheet Servos: 3 x HXT900 9g (or similar)Motor: D2826-6 2200kv Outrunner Motor (or similar)ESC: TURNIGY Plush 40amp Speed Controller (or similar) Prop: GS Sport 6x4E Precision propeller (or similar)These are the formers shown in the position they need to goThe Fuselage SkeletonFirst glue F8 and F9 in place on the “vertical former”Glue the “horizontal former” to the “vertical former” and into F8Glue the top formers” in place as shownPlease note: The side panels and hatch panels are slightly oversize and any excess can be trimmed off after gluing in placeGlue in place the rest of the formers as shownAfter gluing, I use a sanding block to sand the formers to follow the shape of thefuselage and make it nice and smooth for the side panels to be glued on.Cut 2 x 10mm x 6 mm dou- blers from some scrap foam and glue onto the fuselage sides as shown.This is for sanding and rounding a littleAlternative Rudder and Elevator controlThis shows the use of snakes for the control of elevator and rudder.This method has the added advantage of moving the servos up front to help with the balancing of the plane.Horizontal Stab and ElevatorPrepare the stab by gluing in the carbon fibre tube.Chamfer the edge of the elevator and hinge with your favourite method.Glue the control horn in placeTail Fin and RudderHinge the rudder to the tail fin (Vertical Stab) with your favourite hinging method.Attach the control horn to the rudder and firthe servo into the fin Connect the and testThe Side PanelsIf using Depron Stick clear packaging tape on the outside of the panels before rolling.(If using MPF, there s no need to use packaging tape)I use a piece or 20mm (3/4“)plastic reticulation pipe to roll the Depron aroundTail PipeAgain (if using Depron) stick clear packagingtape on the outside of the panels before rolling.IMPORTANT:If using Depron . Before bending-rolling, stick clear packaging tape to the outside of the panels to stop them cracking (If using MPF, there s no need to use packaging tape)The horizontal stab can be glued in place and the control rods / snakes can be fitted and testedAfter test fitting, the LEFT side panels can now be fitted to the fuselage skeletonNow fit the tail finConnect up the servo horns and rodsRout the cables from the motor and servos andtest that everything is working OK.Once you are happy that everything is working OK you can fit the right hand side panel in placeYou can now fit the motor And glue in place the tail cone.The HatchGlue the formers together and then glue on the top panels. IMPORTANT:If using Depron Before rolling the top panels, stick clear packaging tape to the outside of the panels to stop them crack- ing (If using MPF, there s no need to use packaging tape)Before gluing on the top panels, sand the formers and base to follow the contours.Showing tail cone and motor in placeAfter routing the servo wires, you can now attach the wingThe WingGlue the carbon fibre tube in placeHinge the ailerons to the wing with your favourite hinging method.Dihedral BraceOnce you have prepared both halves of the wing you can glue them together with the Dihedral as shown glue the dihedral brace in place (I like to use epoxy glue for this)Place one wing flat on the bench and block the end of the other up by 75mm (2.95 inches)I have used the “Torque Rod” methodfor operating the ailerons, but you could use other methods if you wish.Shape / sand the belly pan to shape and glue into placeLaminate the nose pack, glue into place and sand to shapeI use magnets to hold the hatch in placeStart with the C of G on the spar, turn upside down to make balancing easy
