SIG RASCAL ARF, Assembly Manual, Page: 2 / 18

heat gun to re-shrink the covering but you must be very careful
around any seams or joints. Re-heating seams will cause them to
"creep", making them unsightly. This is especially true with the
Rascal’s inset style of trim scheme. You must also be careful when
using a heat iron or heat gun when working around the window
and windshield areas - heat will distort these plastic pieces.
A very easy way to avoid damaging seams and joints when
reshrinking the covering is to protect the seams with wet paper
towels rolled into strips. These are arranged directly onto the joints
or seams and their coolness protects the seam from shifting or
"crawling" under heat.
For part number reference, your Rascal ARF was covered in
Oracover® film with the following part numbers:
#10 White and
#21-58 Transparent Green or
#21-75 Transparent Violet
REQUIRED TOOLS:
For proper assembly, we suggest you have the following tools and
materials available:
A selection of glues - SIG Thin and Thick CA and SIG
Kwik-Set 5-Minute Epoxy
Threadlock compound, such as Loctite® Blue
Selection of hand tools, such as;
Screwdriver Assortment
Pliers - Needle Nose & Flat Nose
Small Allen Wrench Assortment
Pin Vise for small dia. drill bits
Sandpaper
Hobby Knife with sharp #11 blades
Paper towels
Small Power Drill with selection of bits
You will also be required to make a few solder connections. We
suggest that you have a good soldering iron and good quality
solder and flux. For the pushrod connections, we use and like the
Stay-Brite® Silver Solder products. For electrical connections, use
solder specifically for that purpose.
WINGS:
❑
1) Start by using a hobby knife with a #11 blade to clear out the
rear wing bolt holes on the top and bottom of the wing center
section. Test fit the wing center section to the fuselage and secure
with the provided nylon 4-40 wing bolt. The fit will be good, with
the center section well centered on the fuselage.
❑
2) Remove the center section from the fuselage and test fit the
wing panels onto the exposed plywood dihedral brace ends. The
fit should be firm. Use 5-minute epoxy to join one of the wing
panels to the wing center section. Apply glue to the correct side of
the exposed rib on the center section and also apply a thin coat
onto the plywood brace. Slide the center section plywood brace
into the slot in the appropriate wing panel. Press the wing panel
firmly in place to the center section. Wipe off all excess glue with
acetone or alcohol and tape the panel securely to the center
section - top and bottom. Allow the epoxy to set and glue the
remaining wing panel in place.
❑
3) After the glue has set, use the four provided 1/4" x 10" self-
adhesive strips of white Oracover® film to cover the bottom and
top wing joints, centering the covering over each joint. Save the
excess strip material. Check the fit of the completed wing to the
fuselage. Remove the wing and set it aside for now.
