You will need also the:
CyA glue, CyA glue activator, sharp (modelling) knife, 150 mm extension cable. 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 (Fig. 1). Using the Fig. 2 as a guide, glue in place the bushings for the slab elevator. 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).
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.
Glue the elevator servo in place and install the elevator control rods. Pierce/drill a hole through a cube of EPP and slide
it onto the control rod, to serve as the control rod guide. Check the neutral position of the servo and glue the elevator
lever in place (Fig. 4).
Repeat the process for the other engine nacelle; keep in mind the nacelles are right and left.
Now 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. 5). Work on a flat surface to ensure the complete assembly is not distorted. Check the quality of the
wing reinforcement and glue the fuselage in place (Fig. 6).
Glue the engine nacelles to the fuselage (Fig. 7).
Check the elevator shafts of carbon are coaxial and glue the vertical tail surfaces in place (Fig. 8).
Glue the elevator halves (Fig. 9). Ensure the wing and right and left elevator planes are parallel and that they are at the
same angle relative to the wings.
Using the Fig. 10 as a guide, glue the motor bulkhead, screw-on the motor bearers (Fig. 11) and secure the motor in
place.
Install the speed controller as per Fig. 12. The position of the controller is shown on the Fig. 13. Using a hand-held
soldering gun, cut a hole for the receiver into the fuselage. 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 of the same thickness, and of the necessary length. Glue the engine nacelle upper
part in place (Fig. 14). Now glue the EPP jet pipes to the engine nacelles (Fig. 15) and the doubler of the fuselage
motor section.
The model is now ready for balancing. By shifting the propulsion batteries, set the position of the centre of
gravity to some 320 mm from the motor bulkhead. Then, using a soldering gun, cut 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, to ensure
that the batteries would hold in place without any extra fixation.
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.
