Introduction
This chapter contains description of assembly and disassembly of individual parts of the aircraft. At least
two persons are needed for assembly/disassembly. All parts necessary for assembly are being delivered
with the aircraft.
Before assembly, clean, grease and then secure all pins. Pay attention to correct adjustment of ailerons
and flaps, which is carried out by shortening and prolonging of connecting pushrods.
With each next assembly, it is necessary to replace locking nuts and split pins with new pieces.
After the aircraft is assembled, make deflections adjustment according to levelling record and carry out
engine check with a focus on both fuel tanks function. Check the correct values on fuel indicators.
6.2.
Tailplanes Assembly / Disassembly
At least two people are needed for assembly/disassembly. Pay attention to avoid a fall of small parts into
the inner space of the tail during manipulation!!
Horizontal (HT) tail assembly
•
Vertical tail rudder disassembly
To reach better access to attachment points of the HT, it is recommended to remove the VT rudder.
Unscrew two M5 screws fixing the VT rudder in the lower carrier. Then, deflect the rudder fully to the left
or right. Pull the bottom part of the rudder out of the lower carrier and then, lift the rudder upwards to
remove it out of the upper hinge.
•
Horizontal tail mounting to the fuselage
Remove the cover of the mounting hole situated under the HT on the left side of the fuselage. Connect the
right half of the HT with the elevator first. Insert its crossbeam into the hole in the fuselage and insert the
elevator into the pins in the steering lever at the same time. Connect the left half of the HT same way. At
the same time, it is necessary to get the trim servo wire through the hole into the fuselage.
Install two M8 screws, which connect both halves of the HT, into appropriate holes and screw them into
the bulkhead inside the tail. The screws must be fitted with a locking washer to avoid their self-loosening
and must be properly tightened.
Install M5 screws in the holes situated in the front root area of each half of the HT stabilizer. These fix both
HT halves via connecting tube. Secure the screws by the Loctite glue.
Install the cover of the mounting hole situated under the HT stabilizer on the left side of the fuselage.
Finally, cover the gap between the fuselage and HT stabilizer by any suitable white plastic tape (eg. 3M)
which avoids water intrusion into the fuselage.
