There are two types of screws used in this kit:

Sheet metal screws are designated by a number and a length.

This is a number six screw that is 3/4" long.

Machine screws are designated by a number, threads per
inch
, and a length – for example, 4-40 x 3/4".

This is a number four screw that is 3/4" long with forty

threads per inch.

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 PT-17 Military Stearman ARF is factory-covered
with Top Flite

film. Should repairs ever be

required, MonoKote can be patched with additional
MonoKote purchased separately. MonoKote is packaged
in six-foot rolls, but some hobby shops also sell it by the
foot. If only a small piece of MonoKote is needed for a
minor patch, perhaps a fellow modeler would give you
some. MonoKote is applied with a model airplane
covering iron, but in an emergency a regular iron could
be used. A roll of MonoKote includes full instructions for
application. Following are the colors used on this model
and order numbers for six foot rolls.

Cub Yellow – TOPQ0220

Dove Gray – TOPQ0211

Sky Blue – TOPQ0206

True Red – TOPQ0227

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 

www.greatplanes.com 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.
