REMOVING WRINKLES
The covering of your model may develop wrinkles during shipping and will require the use of a heat gun (HAN100)
and covering glove (HAN150) or covering iron with a sealing iron sock (HAN141) to remove them. Use caution while
working around areas where the colors overlap to prevent separating the colors. Avoid using too much heat, which
could separate the colors. Placing a cool damp cloth on adjacent colors will also help in preventing the separation of
the colors while removing wrinkles.
BUILDING PRECAUTIONS
Prepare the work surface prior to beginning the build. The surface should be soft and free of any sharp objects. We
recommend resting the airframe parts on a soft towel or pit mat to prevent scratching or denting the surface of the
aircraft.
TRANSPORTATION AND STORAGE
Use the three-view drawing on page 90 to determine how much room will be required to transport and store your
model. We also recommend the use of wing and stabilizer bags to help protect these surfaces during transport and
storage. The control horns and linkages can cause damage to other surfaces even when placed in storage bags.
Always transport and store the wings and stabilizer so the linkages do not contact other panels to prevent damage.
CHECKING BLIND NUTS
When building the aircraft, you will be required to thread machine screws into blind nuts. We recommend pre-threading
the screws to make sure the blind nuts are clear of any debris. If the screws do not thread in easily, clear the threads
using the appropriate tap and tap handle.
REPLACEMENT COVERING
Your model is covered with UltraCote® lm in the following colors. If repairs are required, order these coverings to
make those repairs.

stabilizer location. Tie the string to two 48 inch (1200mm)
extensions. Make sure the plugs connect to the receiver.
122. Use the string to pull the extensions through the sleeve. Be
careful not to break the string.
123. Slide the servo routing sleeves as far back as possible.
Mark the sleeves at the bulkhead so the positioning can be
checked before each fl ying session. Use tie wraps to secure
the sleeves to the structure above the location for the thrust
tube, so they don’t come in contact with the exhaust tube
during the operation of your model.
TURBINE INSTALLATION
124. Fit the exhaust guard to the rear of the fuselage so it equally
covers the fuselage. Secure the guard using two M3 x 12
self-tapping screws.
Failure to fit the exhaust guard will result in
heat damage to the wood and covering above
the tailpipe at the rear of the fuselage.
125. Slide the exhaust tube into the rear fuselage from the front of
the fuselage.
126. Align the end of the exhaust tube so it extends 1/4 to 1/2 inch
(6mm to 13mm) beyond the fuselage former at the rear.
It may be necessary to slide a thin steel ruler (or
similar) between the exhaust tube and opening in the
fuselage to aid the tailpipe fitting through the end
fuselage former. This is designed to be a snug fit.
18EN
127. Space the exhaust tube equally between the sides of the
fuselage. Secure the tube using four M3 x 12 self-tapping
screws.
128. Position the turbine so the distance between the tail cone and
exhaust tube match the recommendations from the turbine
manufacturer.
The mounting rails can be modified to fit a variety of turbines.
130. Mount the fuel pump in the fuselage and connect any fuel
lines necessary for the operation of the turbine. Connect the
vent line from the tank. Secure all connections using wire
ties.
Do not use tie wraps to secure the fuel lines.
129. Position the turbine in accordance to the distance relative to
the tailpipe stated in the operations manual of your turbine
manufacturer.
FIN INSTALLATION
131. Secure the lead from the rudder servo and extension using a
commercially available retainer.
