 Materials / items required for assembly:
-
Bonding/glue: Cyanoacrylate medium, activator for cyanoacrylate and cyan spouts dispensers;
-
Finishing sandpaper 500/320
-
Carbon tube diameter 8 mm
-
Carbon tube diameter 4 mm
-
Carbon tube diameter 2 mm
-
Alcol etilico
-
Ethyl alcohol
-
Cloth for ethyl alcohol (for cleaning surfaces to be bonded)
 Preparative surfaces before bonding:
The MB339 model is composed of several sections, which need to be glued together
Each section before being glued must be sanded very quickly to further refine the plan already created by
the press, so that it is smooth and free of debris that might not do well pave surfaces. (Use abrasive paper
500/320).
Afterwards degrease with cloth soaked in ethyl alcohol the surfaces before bonding.
The above operations are very fast to perform, are indications to make the perfect job for the KIT assembly.
Use the cyanoacrylate medium to glue the sections between them, to avoid frittering of glue, use the cyan
spouts dispensers for medium cyan and apply the glue in the edge inside of the plane (not to exaggerate
with the amount, the cyanoacrylate on this type of materile has a strong seal and performs as a weld
between the glued parts) use the activator to accelerate the drying of the glue. It is important to use the
activator and nebulize in small quantities to avoid too rapid drying of the glue.

  • Page 1 Cloth for ethyl alcohol (for cleaning surfaces to be bonded)  Preparative surfaces before bonding: The MB339 model is composed of several sections, which need to be glued together Each section before being glued must be sanded very quickly to further refine the plan already created by the press, so that it is smooth and free of debris that might not do well pave surfaces.
  • Page 2 Once pasted section, in the inner part of the fuselage wipe across the board always with cyanoacrylate medium, the sections have been designed to allow the creation of this bonding also internally in the fuselage. For facilitate the gluing of fusolsgr, divide the fuselage into two parts as in the following picture: And then successively glue the two sections as follows:...
  • Page 3 A practical tip is to drilling the first front section for the front carriage before gluing, see the following photo: In the particular photo of the assembly of the front retractable machine. N.B. The kit used by Turnigy for reach trucks has a 45mm diameter wheel on the front landing gear, I recommend replacing it with a 40mm diameter wheel to give the model the right trim.
  • Page 4  Assembly of the wings : Before inserting and gluing the wing sections, I recommend drilling the holes to screw the machines onto the wing section. It is very important to use a flat head screw of the right length in order to use the entire internal thickness of the wing where there is the structure that guarantees the right seal to the machine and the correct anchorage of the carriage.
  • Page 5 For convenience, also screw the servos into the housing in the wing, use the cable gland inside the wing for the wires. Once the assembly of the two wings is complete, insert them in the central section of the fuselage using a carbon tube with a diameter of 8mm with a length of 75 cm, and use a carbon tube with a diameter of 2mm for the coupling and alignment of the wing, see example in the photo: Carbon tube 8mm...
  • Page 6 N.B. Glue the wing sections together and also on the fuselage with medium cyan As reported in the previous photo, it is very important to glue all the sections of the wings together and also on the support surface of the central section of the fuselage, this guarantees the correct functioning of the whole structure of the wing.

  • Page 8 The brackets are already printed on the moving parts, it is only necessary to prepare the servo tie rod Aileron and flap glued and aligned  Assembly of elevation plane and rudder: For the mounting of the platforms and the rudder, a 4mm diameter carbon tube (which will pass through both shelves) and a 2mm diameter tube which will only be used exclusively for aligning the parts to the rest of the fuselage, therefore not passing through, are required, see photo: All parts must be glued together successively with medium cyan.
  • Page 11 Carbon tube diameter 4 mm also for the rudder section.  Motor assembly : it is recommended to install the motor before assembling the elevation plans The engine is housed immediately after the center section of the fuselage and is accessible from a screwed panel under the fuselage.
