I-16
Dear customer, congratulations on the purchase of the I-16 model. To enjoy building and flying
the model most, please read carefully the building instructions before you begin and make
sure that you understand the building process.
DESCRIPTION OF THE MODEL:
The I-16 model is completely made of the expanded polypropylene EPP. Its light weight (from
160 grams) makes it an ideal model for flying in any environment. Thanks to its powerplant it
is extremely suitable not only for a leisurely flying, but for the air combat as well.
Due to its well-engineered design the assembly of the model would take only about 60
minutes. It would survive unharmed many crashes and mid-air collisions in the air combat
with other models.
BUILDING THE MODEL:
Unless otherwise stated, all parts are to be glued by the medium-thick CyA glue. Start the
building by gluing the elevator joiner in place (Fig. 1). Then glue the empennage to the
fuselage, (Fig. 2) ensuring that the empennage planes are at right angles and at the correct
angles to the fuselage. Then comes the wing (Fig. 4), that has to be glued to the fuselage so
as to keep the symmetry and correct relative angles (Fig. 5). Using the (Fig. 6) as a guide,
assemble the undercarriage leg mounts and glue them into the wing cut-outs (Fig. 7). If you
are not going to fly with the undercarriage, omit this and the next two steps completely. Place
the wheels on the axles and secure them with the quick locks (Fig. 8). At this moment you can
also attach the undercarriage doors (Fig. 9).
Cut out the opening for the elevator servo (Fig. 10), glue in place the elevator control horn
(Fig. 11) and install the elevator push-pull rod (Fig. 12). Glue in place the aileron control horns
(Fig. 13) and cut out the opening for the aileron servo (Fig. 14). Install the aileron servo and
push-pull rods (Fig. 15). Glue the motor mount and connect the controller (Fig. 16). By the
set-screw, attach the motor in the mount (Fig. 17), then insert the receiver into the fuselage.
Place the battery in the opening cut into the wing and fuselage (Fig. 18). Check the position
of the centre of gravity (C/G) and adjust it by shifting battery or, eventually, adding some
weight as necessary. Now the model is ready to fly, it is only necessary to apply the decals
and to trim the controls.
The displacement of control surfaces should be set to about 30 degrees for the first flights,
adding exponential displacement as used to. The model is sufficiently sensitive to controls and
nimble. Always take into consideration your own skills and fly so as not to endanger yourself
or people in your vicinity.
Many happy landings! Your FreeAir.

You will need the following tools and materials:
CyA glue, CyA glue accelerator, a sharp (modelling) knife, and sandpaper. To complete the
model you need the following: a receiver (MZK), two servos (Waypoint), an AC controller
(TMM 0710-3), a battery pack (2-3 LiPol cells of 720-1200 mAh). For the 20/8/16 motor
with two LiPol cells, the 200/130 (8“/6“) propeller is the optimum, the same motor with
the 180/130 (7“/6“) propeller would need three LiPol cells.
