You will need also the:
CA glue, CA glue activator, sharp (modelling) knife, 150 mm extension cable for servo. To complete the model you will need: a receiver
(MZK), servos (Wipont W-060), a controller (TMM-1210-3 or Jeti 12), an accumulator battery (3 LiPol cells of 640-1200 mAh), a motor
(HCS-80/2E or similar of about 80 W output).
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 and by gluing a
servo to the prepared cut-out in the nacelle (Fig. 1). According to the Fig. 2 glue in place the bushings for the flexible attachment of the slab
elevator. Thread the carbon tube through the bushings and slid on the tube the elevator lever and two securing rings (Fig. 3). Slide the securing
rings to the extreme outer position to eliminate any play in the carbon tube (Fig. 4). The carefully glue the rings while ensuring that no glue
would block the pivoting joint. Install the pushrod to the elevator lever arm and to the servo arm and then glue the elevator lever (Fig. 5). Repeat
the procedure with the other engine nacelle (Fig. 6). Do not forget there is a right and a left part.
Now choose the amount of sweep of the wing. Set the angle of the sweep by the auxiliary triangle. Provided the required sweep angle is less
acute, simply cut the triangle to get the required wing sweep (Fig. 7). Using a sharp (modelling) knife, cut in the top and bottom surface of each
of the wing halves a slit some 1-2 mm deep. Push carbon rods into the slits and glue in place by a thin CyA glue. Glue the engine nacelles (Fig.
8) and the vertical tail surfaces (Fig. 9). Check that the position of servos is neutral and glue the elevators in place (Fig. 10). Glue the motor
bulkhead (Fig. 11) and glue in place the doubler of the rear (motor) fuselage section (Fig. 12). Then screw on the motor mounting plate and
install the speed controller. The position of the controller and the receiver is shown of the Fig. 13.
The Fig. 14 shows the placement of the accumulator batteries. Using the soldering gun, cut a hole in the fuselage to place the receiver
(so that the servo cables reach to it easily). Provided the servo cable is long enough to reach the receiver, we need not to splice the extension
cable. Connect to the power cables of the controller the extensions or cut the controller cables short and splice them with longer cables of the
same cross-section. The model is now ready to be balanced. By shifting the propulsion battery the actual centre of gravity could be established
some 300-320 mm from the motor bulkhead (Fig. 15). For the more swept wing the position of the centre of gravity is 300 mm from the motor
bulkhead, for the fully spread wing (with minimum sweep) the distance is 320 mm. Using a soldering gun, cut an opening for the accumulator
battery; the hole’s dimension should be some 2-3 mm less than the battery outer dimensions, to ensure tight fit without any further fixing.
Now the model is complete, you can enhance its appearance by applying the marking self-adhesive decals. For the
first flight, set the deflection of the controls to the half of their travel.
As the model, due 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 slowly.
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 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.
