How to use Fliteskin
FliteskinTM can be attached to a balsa or ply frame
in 3 different ways: with GorillaTM polyurethane
glue, with a good quality contact cement or slow curing CA (Cyano)
glue suitable for fiberglass. In every case the areas to receive
the glue need to be sanded with 80/100 grit or similar.
not use heat.
Application on framed wings:
Un-roll the sheets in a clean table or building
Position sheets over the plans to determine
Sand the entire wing top with a long T sand paper
to make sure all ribs are even.
Using sharp knife (box cutter), cut the sheets so
they will overlap 1/4"
to 1/2" (6,5mm to 12,5mm) over the leading edges and wing tips.
Position the skin in place over the surface to
sheet (dry) and pin trough the skin in 2 or 3 places on the
Leading edge of the wing or, if covering a fuselage, over a
supporting stringer. These will
be the positioning guides.
Next remove skin from frame and sand with rough
sand paper 80/100 over those areas that will be in contact with
the surface and specially the outer edges.
Apply thin bids of Gorilla glue only to the frame (ribs,
spars, etc.) After positioning the skin in place using the pin
holes previously made, stack layers of soft magazines over the
entire wing. This work very well to assure the skin conforms to
Next place as many pins over the leading edge as
sure the entire leading edge is tight against the wood.
Only at the leading edge the skins will be pinned
Once the glue is dry, you will remove magazines
and pins and repeat process in the opposite side.
After both Top and Bottom are sheeted you will
fiberglass the Leading edge and wing tips using strips
of glass cloth and resin. Tip: use masking tape to define the
leading edge along the wing. Spray the L.E. with a light coat of
3M77 and position the fiberglass cloth in place. Brush two coats
of finishing resin and let it set.
Once resin has set, trim the L.E with sharp knife using the
masking tape as reference.
Application on foam wings:
Sheeting foam wings with FliteskinTM is so simple and
the results are so great that after the first use, you'll never go
back to the long and messy process of sheeting with
balsa, fiberglass and resin.
should be glued directly to foam cores using Gorilla Glue which is
safe on foam.
Prepare the foam cores as you would for balsa sheeting (cut
channels, install spars, etc).
Install leading edges and wing tips. Sand even with the surface of
a metal ruler and a hobby knife, cut the pieces of FliteskinTM to
fit the core (top & bottom) with an extra 1/4" or so to cover
Leading edge and/or tips. It takes about 4 or 5 scores of the
blade to cut through the sheet, alternating both sides of the
blade works best. FliteskinTM can also be cut with
scissors but the ruler and knife method assures a straight line
cut over the plans. You can choose to add the leading edge and
wing tip after sheeting is completed but the first option
facilitates fiber glassing.
a little experience you can glue top and bottom skins in one shot;
lay both pieces of sheeting flat on the table (trailing edge to
trailing edge) and join with masking tape on the outside surface.
Spread the glue evenly with trowel, creating a
THIN film over the COMPLETE surface of the skins. Do not apply
glue to the cores. Allow a thicker coat on the edges to assure a
good bond and lay over the foam core.
assembly inside the foam cradle placing a flat board on top with
enough weight to keep from lifting.
the assembly dries, it will be very rigid and strong. Now you
can cover the leading edges and wing tips with a strip of glass
Ailerons and elevators can be cut and hinged using balsa blocks.
NEVER apply HOT IRON directly to
Frequently asked questions:
Yes, epoxy resin is the main ingredient in the sheets. The expansion of
the polyurethane glue increases the area of contact and it works well on
wood frames. (in foam wings you will need a trowel for the application of the glue)
