Great Planes Siren EP ARF - GPMA1065 - Manual (Page 5)

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" 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 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

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.
