Lanier R/C
Sukhoi SU 31M
Instructions
Before starting to build, we urge you to read
these instructions while reviewing the plans.
They contain some important building
sequence as well as instructions and
warnings concerning the assembly and use
of this model. At least read what we have to
say and then make your own determination.
It will save you some time. We expect that
you have had building experience so, every
minute detail is not covered. However the
instructions and plans together will allow you
to produce a first class model.
Fuselage
Begin construction by laying out the fuselage
top and sides. Because of the size it was
necessary to make them two pieces that you
join with a finger joint.
Lay the front and rear pieces on wax paper
and fit the joints together. Glue with CA. After
it has cured you will make a left and right side
by gluing the servo mount doublers on the
inside at the rear servo holes.
Glue a scrape piece of 1/8” ply over the finger
joint at the top and bottom on the inside of
each fuselage side being sure to leave room
at the top for the 1/8” top, and ¼” at the
bottom for the stringer.
Locate the ¼”x1/4”x48” spruce stringers and
glue flush with the bottom edge of each
fuselage side. Start at the rear of the notch
for the landing gear plate and go all the way
to the tail wheel plate. Use a short piece and
glue it flush with the bottom over the gear
plate mount at the front to reinforce it.
After the fuse is framed up the finger joints
will be removed by cutting between the
cutouts at the front and rear of each joint.
