drive operation You may wish to experiment with
various other prop sizes in nylon and wood, to best
match your motor, but the Gnsh 8 x 4 is the best
place to start
SELECTION OF WHEELS
Because weight is such an important factor in
electric powered models, we strongly recommend
that you purchase lightweight wheels, such as Dave
Brown "Lite Flite" wheels or Zinger lightweight
wheels
GLUES (ADHESIVES)
If you look at the "ITEMS NEEDED" list you
will see that we recommend only two basic types of
glue for building the PT-Electnc.-.CA glue and
epoxy.
CA (Cyanoacrylate) glues are great for model
building because they set fast Rather than pinning
glued joints together and waiting for hours while the
glue dries, CA glues will harden in a few seconds
while you hold the parts together Thin CA runs
right into a good fitting joint, so you can assemble
the parts first, then apply thin CA Thick CA is
more like syrup and it will not harden until you
press the two parts together squeezing the glue out
to a thin layer A related and very handy product is
CA Accelerator spray (Zip Kicker or Hot Shot),
and is used to instantly harden CA glue When using
CA glues " trial fit" the parts to make sure they
fit well before gluing because they don't give you
a second chance The most common mistake made by
new modelers is using too much CA glue Rather
than squeezing the bottle, it is usually sufficient to
touch the tip of the applicator spout to the joint being
glued and allow a few drops of CA to flow into the
joint.
If you need time to position glued pieces cor-
rectly or need extra strength, use epoxy glue Epoxy
is normally used in the firewall and motor mount
area and when gluing the two wing panels together.
Five minute epoxy starts to harden in 5 minutes)
is great for most applications If you need longer time
use 15 or 30 minute epoxy You need not use large
amounts of epoxy Squeeze out the amounts of epoxy
and hardener that your particular brand requires.
For example, some epoxies use equal amounts and
some use a 1 to 2 mixture Mix these together Coat
one piece with epoxy, squeegee the excess glue off
with scrap wood The epoxy glue will work better if
there isn't too much oozing out at the edges of the
glued piece Wipe off any of this excess glue with a
tissue.
In any case, glue is never a substitute for a
good-fitting joint, once the Joint is formed, use a
minimum amount of glue and wipe off the excess
with a tissue Clamp, pin or hold the Joint while the
glue is drying.
Remember: Take your time and follow di-
rections to end up with a well-built model that
is straight and true.
