IMPORTANT BUILDING NOTES
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" [1.91mm]
Machine screws are designated by a number,
threads per inch, and a length.
For example 4-40 x 3/4" [1.91mm]
• 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 used 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 we will tell you what type of glue to use.
• Whenever just epoxy is specified you may use either
30-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.
• Occasionally we refer to the top or bottom of the
model or
up or down. To avoid confusion, the top
or
bottom of the model is as it would be when the
airplane is right side up and will be referred to as
the top even if the model is upside-down during
that step,
i.e. the top main spar is always the top
main spar even if the wing is upside-down when
you are working on it. Similarly,
move the former
up means move the former toward the top of the
fuselage even if the fuselage is upside-down when
you are working on it.
• When you get to each step, read that step
completely through to the end before you begin.
Frequently there is important information or a note
at the end of the step that you need to know before
you start.
• 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.
• Note that there are four plan sheets. Two of them
must be cut along the dashed lines and joined with
tape. The other two plans are used separately.
