    This is a scratch built model of an enlarged Paul Bradley’s reproduction of the
    1950 Top Flite Jigtime Model Piper Vagabond. I used 10 10”x 14” styrofoam meat trays.
    The thickness is approx. 5 mm; you can get these from your local grocery meat
    department however you may have to buy a whole pack.

    The first step is to remove the rim from the trays; any razorblade type knife will work.

    Join two trays by overlapping and cutting the ends; this will make the ends
    line up very close with little gap. Glue ends with any foam safe glue. I use
    a low melt hot glue.

    Trace your template of the fuselage side.

    [​IMG]

    Lay traced side on top of other side and tape ends, cut both sides using a straight edge
    when possible, this will make sides the same shape and size, layout
    former locations on the inside.

    Cut out formers and motor mount holes.

    [​IMG]

    Glue formers in place; use a small square to make formers perpendicular;
    bevel inside of tail before joining ends.

    Insert sticks for wind mount and epoxy in place; epoxy motor mount.

    Form windshield and nose cover; glue in place and trim to side
    of fuselage.

    Layout stab and rudder; cut and round edges; cut control surface
    and bevel hinge edge at 45 degrees.

    [​IMG]

    Glue stab and rudder in place; make sure they are straight and square;
    cover top up to wing opening and trim to side.

    Use clear tape for elevator and rudder hinge; install servos, control horns and
    push rods.

    [​IMG]

    Make landing gear from piano wire and laminate in place; use light weight
    wheels.

    [​IMG]

    Cover bottom, add nose cap and trim to side.

    [​IMG]
    [​IMG]

    Round edges with fine sandpaper and cut nose off at front of first former.
    Nose can be reattached with tooth picks.

    [​IMG]

    Cut out wings; glue tips in place.

    Make spar from 4 ¼” x 5/32 dia. aluminum tubing; bend at 1” from each
    end to desired dihedral; insert 1/8 dia. x 12” bamboo skewer in ends.

    [​IMG]

    Layout location for spar and cut channel; glue wing sections and spar in place;
    round front top edges and brake sharp edges on back; glue heavy paper at rubber
    band intersections.

    Install radio equipment and motor.
