EASY
Dear customer, congratulations on the purchase of the Easy model. Before you begin,
please, read carefully the building instructions and make sure that you understand the building
process.
DESCRIPTION OF THE MODEL:
The model is completely made of EPP. With its weight beginning at 230 grams it is
an ideal model for flying in any suitable spot (e.g. a school playground or in the street). It
is intended for beginner pilots. To power it you may use a brushes motor Mig 280 and 2
LiPol cells. Thanks to a well thought-out design the construction would take only about 60
minutes.
BUILDING PROCESS:
Use medium or thin CA glue to glue all parts. The building begins by gluing the wing
together (fig. 1). Further make a shallow cut in 1/3 of the wing from the leading edge, to
insert the Al wire spar. Push the wire into the slit (fig. 2) and adjust the dihedral (fig. 3). Less
experienced pilots should have cca 60 mm dihedral, more experienced pilots some 40 mm.
Both wing halves should have the same dihedral! When you are satisfied with the dihedral,
apply thin CA glue to fix the wire in the wing. Glue the stabilizer to the fuselage (fig. 4), glue
the vertical fin to the fuselage (fig. 5) while controlling the geometry of the tail with respect
to the fuselage. Cut a slit in the controls and glue in the respective control horns (fig. 6,7). Cut
a slot for tail control servos in the fuse. The slot should be 1 to 2 mm smaller than the size of
the servos. Wrap the servos in adhesive tape and glue them in the fuse using CA glue. Install
the pushrods (fig. 9, 10). The recommended wiring of the DC power train is on the fig. 11. Glue
in the motor mount (fig. 12). Fig. 13 shows the location of the ESC and the receiver. Use rubber
O-ring to attach the motor to the mount (fig. 14). Glue the Al stick under the LE of the wing
(it holds the wing retaining rubber loop). The battery is initially held in place by a rubber loop.
Shift the battery to find the correct centre of gravity (the CG is 50 +- 5mm from the LE). When
you find the correct position for the battery, cut a slot in the fuselage to insert the battery into.
Now the model is ready. Check if you have the right control throws and you can go flying.
This model is no toy – therefore avoid flying in crowded places or such areas 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.
