F-15 Eagle
Dear customer, congratulations on your purchase of our model of the famous F-15 Eagle
fighter. Before commencing its building, please study the assembly instructions carefully and
make sure you understand the building process. If need be, contact the manufacturer or your
dealer.
DESCRIPTION OF THE MODEL:
The model is completely made of EPP and has some carbon components. With its weight
beginning at 250 grams it is an ideal model for flying in any suitable spot (e.g. a school
playground or in the street). It is intended not only for experienced pilots, but also for the
advanced modellers. To power it you may use a motor from our production, e.g. the HCS-
80/2E, and three Lithium Polymer cells. Thanks to a well thought-out design the construction
would take only about 90 minutes.
BUILDING PROCESS:
Unless otherwise stated, all joints should be glued with the rapid CyA glue. Start the
building by assembling the engine nacelles (Fig. 1, 2). Then glue the wings to the fuselage
central part, and, using a sharp modelling knife, cut a 1-2 mm deep slit into the wing from
both upper and lower side. Press the carbon spar (rod) into the slit and glue there from both
sides, using thin CyA glue (Fig. 3). Work on a flat surface to ensure the complete assembly is
not distorted.
Cut the openings for servos into the fuselage centre section and glue the centre section in
place (Fig. 4).
Glue the securing ring to the end of the carbon shaft of the elevators. Using the Fig. 5 as
a guide, cut the grooves in the fuselage central part and, according to the Fig. 6, glue the
mechanism of the slab elevators in place.
Insert the carbon tube through the location grooves and slide onto it the elevator lever, then
the two securing rings, two from each side, respectively (Fig. 3). In the fuselage part, cut the
grooves for the elevator shaft bushings. Move the securing rings to their extreme external
positions to eliminate any play in the carbon tube. Then carefully glue the rings, ensuring at
the same time the freedom of movement of the carbon tube. Using the Fig. 4 as a guide, glue
in place the bushings for the slab elevator. Pierce/drill a hole through a cube of EPP and slide it
onto the control rod, to serve as the control rod guide. Glue the elevator servo in place (Fig. 5),
setting the correct distance according to the position of the cut-out in the nacelle, and install
the elevator control rods (Fig. 6).
Check the neutral position of the servo and glue the elevator lever in place (Fig. 7). Ensure
the wing and right and left elevator planes are parallel and that they are at the same angle
relative to the wings. Glue the engine nacelles to the fuselage (Fig. 8). Glue the fuselage main
part (Fig. 9) and the vertical tail surfaces (Fig. 10). Using the Fig. 11 as a guide, glue the
motor bulkhead and the rear fuselage aluminium doubler, screw-on the motor bearers (Fig.
12) and secure the motor in place.
Install the speed controller as per Fig. 13. Glue the engine nacelle upper part in place
(Fig. 14). The location of the accumulator battery is shown of the Fig. 15. Using a hand-held
soldering gun, cut a hole for the receiver into the fuselage (place the hole so that the servo
cables would reach it). If the controller’s servo cable is long enough, there is no need to use
an extension one. Connect cable extensions to the power cables of the controller, or cut the
original cables short and splice them with new cables as long as necessary. The model is now
ready for balancing. By shifting the batteries, set the position of the centre of gravity to some
320 mm from the motor bulkhead. Then cut, using a soldering gun, an opening for the battery
pack; the dimensions of the battery opening shall be some 2 to 3 mm less than the outer
dimensions of the battery pack, so that the batteries would hold in place without any extra
fixation.
Now the model is complete. For the first flight, set the deflection of the controls to the
half of their travel. As the model, thanks to the propeller torque, tends to roll to the left, set
the trailing edge of the right half of the elevator some 4 mm up. The model has specific flight
characteristics – thanks to its layout it can fly not only fast, but also very slow. Bear in mind
that the propeller torque effect is much more pronounced during slow flight, especially after
the launch, and the model rolls slightly to left.
This model is no toy – therefore avoid flying in crowded or such places where health or
property not only of yourselves, but also of third persons could be jeopardised..
Lots of fun and many happy landings wishes FreeAir.
