When you see the term
test fit
in the
instructions, it means that you should first
position the part on the assembly
without using
any glue
, then slightly modify or
custom fit
the
part as necessary for the best fit.
·
Whenever the term
glue
is written you should
rely upon your experience to decide what type
of glue to use. When a specific type of adhesive
works best for that step, the instructions will
make a recommendation.
·
Whenever just
epoxy
is specified you may use
either
30-minute (or 45-minute) epoxy
or
6-
minute epoxy. When 30-minute epoxy is
specified it is
highly
recommended that you
use only 30-minute (or 45-minute) epoxy,
because you will need the working time and/or
the additional strength.

Photos
and
sketches
are placed
before
the step
they refer to. Frequently you can study photos
in following steps to get another view of the
same parts.

The stabilizer and wing incidences and engine
thrust angles have been factory-built into this
model. However, some technically-minded
modelers may wish to check these
measurements
anyway. To
view
this
information
visit
the
web
site
at

and click on “Technical
Data.” Due to manufacturing tolerances which
will have little or no effect on the way your
model will fly, please expect slight deviations
between your model and the published values.
