There are two types of screws used in this kit:

Sheet metal screws are designated by a number and a
length. For example #6 x 3/4" [19mm]

This is a number six screw that is 3/4" [19mm] long.

Machine screws are designated by a number, threads per
inch and a length. For example 4-40 x 3/4" [19mm]

This is a number four screw that is 3/4" [19mm] 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 Ryan STA-M is factory-covered with Top Flite

MonoKote 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.

Aluminum (TOPQ0205)

Cub Yellow (TOPQ0220)

True Red (TOPQ0227)
