WWII Fighters
Dear customer, congratulations on the purchase of the Micro WWII (P-51 D Mustang,
La-5, Bf- 109, Spitfire, A6M Zero, Fw 190) 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 model is completely made of the expanded polypropylene EPP, and its design is
optimised for combat flying and aerobatics. Its light weight (from 115 grams) makes it an
ideal model for flying in any place – e.g. school playing field or in the street. It is designed not
only for the experienced pilots, but for the advanced modellers as well in mind. Thanks to its
powerplant – we suggest one of our motors e.g. the HCS-40/2-3, and 2 LiPol cells. Thanks to
its well thought out design the actual building process would take about 60 minutes.
BUILDING PROCESS:
Unless otherwise stated, all parts are to be glued by the medium-thick or thin CyA glue.
Start the building process by gluing the elevator joiner in place (Fig. 1), making sure that it
is free to rotate. Now glue the horizontal tail to the fuselage, checking all the time for being
perpendicular to the fuselage (Fig. 2). In the same way glue the vertical tail with rudder
in place, checking continuously until the glue dries that the control surface hinge is free to
rotate (Fig. 3). Ensure especially that the gap between the rudder and the fuselage remains
free. Using a sharp knife, cut the slits for the control surface, elevator levers (Figs. 4). Glue
the levers using a CyA glue. Install the control surface servos (you may glue them either by
their flanges, or, after wrapping the servos in a self-adhesive tape, glue them in place by
their body). Use wires to make the control surfaces’ control rods (Figs. 5). Now assemble the
wings, using a sharp knife, cut the slits for the wings spar (Fig. 6). Install the aileron servo
and its control rods (Fig. 7,8). Ready the powerplant (the recommended equipment is the HCS
C 40/2E motor, the Jeti 08A controller and the Penta receiver). Sanding the fuselage nose
lightly, make a bevel of about 3° angle, to get the same right (starboard) side thrust of the
motor. Glue the motor bearer and the holding wire for motor mount parts utilised as the outer
reinforcement to the fuselage nose; the rods should be glued with a thin CyA glue (Fig. 9). Cut,
using a sharp knife, a slit from the motor bearer to the receiver compartment in the fuselage
(Fig. 10). Cut an opening for the controller, taking care to prevent the fuselage from opening
too much . Connect the receiver with the servos and glue the wing to the fuselage (Fig. 11).
Now attach the propeller and insert the battery pack (LiPol 640 mAh) into the opening in the
fuselage. If you use other type of battery pack, modify the opening, using the hot knife or
solder gun to cut the EPP. The centre of gravity (CG) of the model is 40 mm to the rear of the
wing leading edge. Set the control surface displacement – the elevator should have -/+ 10
mm and the ailerons -/+ 12 mm, for pylon racing the elevator deflection should be -/+ 5 mm.
More experienced pilots need not to limit the deflections. When hand-launched, it flies straight
and level, with no tendency to swing or turn/roll.
This model is no toy – avoid therefore flying in crowded or similar places where health or
property not only of yourselves, but also of third persons could be jeopardised.
Many happy landings wishes FreeAir.
