Note: please read all the instructions before you begin construction. Handle the parts of this
kit with care so you do not damage any of the structure or covering. Inspect all the parts for
any shipping damage and report any issues to as soon as you can. Make sure you have a flat
and sturdy workbench and follow all safety advice for the tools and adhesives you plan to use.
Aircraft Covering
Varying temperatures and storage delays can cause covering material to loosen over time and
transportation. We recommend lightly going over all the covering with a covering iron set
at medium temperatures. Be sure to use a soft cover over your iron so you do not scratch the
covering surface. Be sure you go over all seams and edges of the covering to assure it is
secure to the airframe and other covering. Be careful not to apply too much heat or you may
cause bubbles or damage to the covering. A heat gun may also be used along with a soft
cotton cloth to shrink and adhere the covering. Again, be extremely careful when using a
heat gun.
Some modellers prefer to seal the hinge gaps using strips of appropriate covering or clear trim
tape. We have found this to be helpful with models intended for higher speed flight or models

with unusually large hinge gaps. Aircrafts that utilize a very tight double beveled hinge line and
do not normally require this step. Sealing the hinge gaps is therefore left as an option for
modellers.

Construction
1. Rudder Assembly
1.1 Locate rudder, a control horn and base plate. Rudder is driven by push-rod, servo bay
is on the right side of the fuselage.
1.2 Locate the slot for control horn on rudder, remove the covering over the slot with
heated soldering iron or sharp hobby knife, and make sure you do it on the right side of the
aileron. Insert control horn into base plate then into the slot, trace the edge of base plate with
hobby knife then remove the underlying covering.

1.3 Use some fine sandpaper to roughen up the root of control horn where will be glued into
the slot.
1.4 Fill the slot and coat the root of control horn and the bottom of base plate with 30 minute
epoxy, insert the horn into the slot, press it down firmly. Wipe off excessive epoxy with alcohol
wipes. Set aside until cured.
1.5 Use CA glue to connect hinges for rudder.
1.6 Cut the covering from the rudder servo slots from corner to corner and iron down inside
the openings. Connect servo wire extensions to your servos and secure the connections with
the supplied clips. Feed the servo wires into the fuselage. The screw holes for servo
mounting are laser pre-drilled, it is advisable to apply some thin CA to strengthen them, Install
the servos and screw firmly in place.

1.7 Use your radio to set the center of servo and then assemble and adjust the length of
the control rod. The servo arm should be as close to perpendicular to the control rod as
possible while the aileron is at neutral. Double check all screws, bolts and nuts to assure
proper installation and operation without binding. Once satisfied, permanently attach the ball
links to the servo arms and horns with the supplied screw and nut.
1.8 We recommend using KUZA 1” aluminium CNC servo arm (sold separately) for rudder
control.
