tape. For the purple, violet, and white model, silver or light red trim
looks great. Whatever color you choose, be sure to use good 
quality striping tape, applying it smoothly, avoiding wrinkles when
working the tape around the corners. When the trim is complete,
seal it in place with low heat (180

SIG "SUPER

STRIPE" color trim tapes worked very well on our models.

Another detail that dresses up the looks of the Sun Dancer 50 
is the windshield frame.

Since the windshield is screwed to 

the fuselage, it is easy to remove and paint the frame.

Use 

contrasting color paint or striping tape on the raised "frame" 
portions of the windshield to simulate the metal windshield framing
used on full sized aircraft.

To assure good adhesion of your

trim,always wash the windshield in warm water and liquid dish
soap. Rinse and dry completely before applying.

While the windshield screws are out, use thin CA and a fine 
applicator tip to put a drop or two of glue into each screw hole to
harden the threads. This will help to prevent these screws from
loosening from vibration.

The firewall and tank compartment of your Sun Dancer 50 has
been factory treated with fuel proofing at the factory. However, you
may wish to add additional fuel proofing of your own. We suggest
using thinned epoxy glue or water-soluble polyurethane varnish.
Simply remove the hatch under the tank compartment for access
to the interior of the tank compartment.

MODELER’S TIP: To help locate the drilled holes needed to
mount the nylon control horns and nylon inter-connect horns,
a small template, which is shown below, that can be used to
make a simple jig.
