You will need the following tools and materials:
CA glue, CA glue accelerator, a sharp (modelling) knife. To complete the model you will need: a receiver (MZK), servos (W-038), a controller (HCS
C 12A or similar), a battery pack (2-3 LiPol cells of 360-640 mAh), EDF 40 from GWS.
Description of the model:
The model is completely made of EPP. With its weight beginning at 120 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 brushless
motor Feigao with 3 LiPol cells. Thanks to a well thought-out design the construction would take only about 60 minutes.
Building process:
All EPP parts of this model can be glued by thin CA glue, only the Duct which is made from depron needs foam safe glue. First of all roll the depron
duct into a tube with a rough
diameter of about 20-35 mm (Fig. 1). On this tube
roll the depron part so that it tapers down to the tail (Fig. 2 and 3).
You can now glue the depron edges together with foam safe CA (Fig. 4) or it can be fixed together with tape (Fig. 5). In the picture number 6, both
methods are shown.
Put the EDF unit into the Depron Duct (Fig. 7). It is not necessary to glue the EDF unit in place, this means that if you have any problems with the
EDF or motor that you can remove it again in the future.
Using a sharp knife trim the fuselage (Fig. 8). In the fuselage cut opening for motor
supply cable (Fig. 9).
Put the EDF & duct into the fuselage and glue the depron duct to the fuselage, then trim overlaped part of adjutage at the end of the fuselage (Fig. 10).
According to Fig. 11 trim motor nacelle and glue them to fuselage (Fig.12 and 13) . If you want to hide the elevator pushrod to be hidden inside the
fuselage, you need to leave the left nacelle until the control the elevator pushrod has been installed.
In elevator cut the groove and glue the control horn into it (Fig. 14), take care that the control horn is on the same side as elevator servo.
Glue elevator and rudder (Fig. 15), take care to make sure that they are perpendicular to each other.
In the wing cut the groove and glue aileron
control
horns (Fig. 16) and install aileron
push
rods (Fig. 17).
Into the prepared groove glue the elevator servo and install rods (Fig. 18 and 19), which we can disguise by motor nacelle.
Join servos and controller to the receiver (Fig. 20). Cut an opening for the controller in the fuselage or wing depending which you prefer. Check that
everything works, glue the wing to the fuselage (Fig. 21). Again check the alignment of the wing, fuselage and tail.
Now cut a hole for the battery pack to fit in the fuselage (Fig. 22). Check the balance of the model before doing this to ensure correct CG placement.
Antenna of the receiver we can take out for example according to the (Fig. 23). The centre of gravity
is 45 mm back from the leading edge of the
wing.
Now the model is complete.
For the first flight, set the deflection of the controls to the half of their travel. The model has specific flight characteristics – thanks to its layout it
can fly not only fast, but also very slow.
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.
