D6-05 Attaching the undercarriage mounts to the bottom of the fuselage.
D6-06 The parts that make up the cowl (1/4" balsa).
D6-07 Building the horizontal stabilizer and elevator.
D6-08 Building the vertical stabilizer and rudder.
D6-09 Cowl being assembled.
D6-10 Outside of cowl rough sanded to shape.
D6-11 Inside of cowl sanded to shape.
D6-12 Aft fuselage side being assembled.
D6-13 Pushrod guides being added to fuselage sides.
D6-14 Aft fuselage sides being joined together.

D6-16 Elevator and rudder pushrods.
D6-17 Pushrods connected to control surfaces.
D6-18 Pushrods connected to servos.
D6-19 Wire parts for the undercarriage and tail skid being formed.
D6-20 Copper wire applied to UC joints.
D6-21 UC joints soldered.
D6-22 Tail skid joints soldered.
D6-23 Parts to make up wheels.
D6-24 Wheels being assembled.
D6-25 Wheel covers printed on cardboard from file folders.
D6-26 Wheels mounted on axles.
D6-27 Standard wheel collars used as spacers to keep wheel from binding on UC struts.
D6-28 Wheels retained on axles by epoxying small washers to axles with JB Weld.
D6-29 Notches cut in ends of wing spars to join with wing tip plates.
D6-30 Wings being assembled-spars, bottom sheeting, ribs and tips.
D6-31 Wings being assembled-leading edges, trailing edges, top sheeting and ailerons added.
D6-32 File folder cardboard being fitted to the top of the fuselage to be used as a template for the top sheeting.
D6-33 Fuselage top sheeting being glued.
D6-34 Fuselage top sheeting and and turtle deck stringers added.
D6-35 Rear of fuselage below vertical stabilizer filled with scrap balsa.
D6-36 Cockpit floor sheeting with a hatch for access to the elevator and rudder servos. (before top sheeting was applied)
D6-37 Servo access hatch open.
D6-38 Access to elevator and rudder servos is through cockpit opening. (top sheeting applied and cockpit floor hatch removed)
D6-39 Aileron servos being mounted to cover plates.
D6-40 Aileron servos installed on wing-top view.
D6-41 Aileron covers from bottom of wing.
D6-42 A 3/32" x 3/16" balsa stick applied to the front of the aileron to serve as a pivot point for CA hinges. Stick is parallel with bottom of aileron and sanded with a 25 degree bevel.
D6-43 1/8" balsa sheeting glued to top of axel to act as fairing. (viewed from bottom)
D6-44 1/16" sheeting is laminated to the bottom of the 1/8" sheeting on both sides of axle and sanded to a streamline shape.
D6-45 Major components assembled-front view. (ignore the dihedral on the bottom wing. It will be 0 degrees with final assembly)
D6-46 Quarter view.
D6-47 Rear view.
D6-48 Battery mounting plate as seen through bottom hatch at front of fuselage.
D6-49 Latch for battery hatch made from 3/32 inch brass tubing and 1/16 inch piano wire.
D6-50 Battery hatch in place on bottom of fuselage.
D6-51 Cowl is mounted to fuselage with three pairs of 1/16 x 1/8 rare earth magnets.
D6-52 Aileron servo extensions made from 26 ga ribbon cable.
D6-53 Aileron servo end of extension cable.
D6-54 Extension leads from each aileron are joined together in the upper wing center section then routed to fuselage along the left aft cabane strut.
D6-55 Aircraft covered with polyester tissue (polyspan) and the covering sealed with one coat of Minwax Polycrylic.
D6-56 Temporary jigs to set the down and right thrust of the motor mounting stick.
D6-57 Motor mount being glued to the firewall.
D6-58 Base of motor mount reinforced with balsa strips.
D6-59 Cockpit coaming made from shrink tubing preshrunk over a length of thick solder molded to the shape of the cockpit opening.
D6-60 Lower wings being glued to fuselage. Sandwich bags full of sand keep the wings flat and in place (dihedral = 0 deg).
D6-61 Ailerons servos are connected to the control horns with pushrods.
D6-62 Top wings being glued to the cabane struts. Again the wings are weighted with sand bags. The interplane struts were attached in a similar manner.
D6-63 Undercarriage is attached to the mounts with carpet thread and thin ca glue.
D6-64 Tail skid is attached in the same manner as the UC. Because there is no access to the TS mount the TS was attached to the mount before the mount was glued to the fuselage.
D6-65 Pins made from toothpicks are used to align and reinforce the vertical stabilizer attachment to the fuselage.
D6-66 Rigging points are made from the shank and eye of #10 fish hooks.
D6-67 Small fuel tubing was split lengthwise and placed over the undercarriage struts to bring them up to scale steel tubing diameter. The fuel tubing was later painted.
