3- Assembly
Please note that pictures are for reference only. Some pictures shown are from other models which
follow the same build steps.
MAIN LANDING GEAR ASSEMBLY AND WING WIRES:
Position the fuselage upside down and screw on the carbon undercarriage to the fuselage using the nuts
and bolts provided, trapping the provided metal guide wires support between the landing gear and the
fuselage.
We will crimp the tension wires to the plate later in this manual.
Screw the wheel axles on to the landing gear, and then slide on the wheels and secure in place with the
provided grub screws.
Some users may prefer to leave the wheels until the end of the build, to prevent the model
moving on the build table.

TAIL WHEEL AND ELEVATOR GUIDE WIRES INSTALLATION:
With the model still upside down, draw the centre line of the section where the carbon tail wheel unit
will be located, and then mark the location where you need to drill the holes for the bolts that will hold
the tail wheel in place.
Note that in front of the tailwheel assembly you will need to attach the cross member for the elevator
guide wires.
Insert the blind nuts on the inside of the fuselage and secure the tail wheel and cross member with the
bolts provided. Attach the spring at one end to the metal arm on the tailwheel and the other end to the
underside of the rudder itself using the small woodscrew provided.
We recommend to keep the pivot point of the tail wheel as in line with the hinge line as
possible to assure a bind free movement of the springs.

INSTALLING THE CONTROL HORN ON THE ELEVATOR:
It is very important to sand horn to assure a strong bond once glued to the model.
Locate and cut the covering where the horns will be glued
Glue them to the surface using epoxy glue
Excess epoxy glue can be removed with acetone

INSTALLING THE CONTROL HORN ON THE RUDDER:
It is very important to sand horn to assure a strong bond once glued to the model.
Locate and cut the covering where the horns will be glued
Glue them to the surface using epoxy glue
Excess epoxy glue can be removed with acetone
