118. Mount the fuel pump in the fuselage and connect any fuel
lines necessary for the operation of the turbine. Mount the
vent fitting in the bottom of the fuselage and connect the vent
line from the tank. Secure all connections using wire ties.
Î Do not use tie wraps to secure the fuel lines
as they will deteriorate over time.

FIN INSTALLATION

119. Locate the tube in the rear fuselage in the fin location. Tie the
string to a 48 inch (1200mm) extension.
120. Wrap tape around the connection between the plug and string
to make pulling the extension through the tube easier.
121. Use the string to pull the extension through the tube. Be
careful not to break the string. Connect the lead from the
rudder servo and extension using a commercially available
retainer.
122. Mix 1/2 ounce (15ml) or 30-minute epoxy. Use an epoxy
brush to apply epoxy in the tubes in the fuselage for the fin
and to the surrounding wood.

123. Fit the fin into position. Place a small piece of plastic in the
hinge line and along the bottom of the rudder to prevent
gluing the rudder to the fuselage. Remove any excess epoxy
using a paper towel and isopropyl alcohol.

STABILIZER INSTALLATION

124. Locate the tube in the rear fuselage in the stabilizer location.
Tie the string to two 48 inch (1200mm) extensions. Make
sure the plugs connect to the receiver.
125. Use the string to pull the extensions through the tube. Be
careful not to break the string.
126. Insert the stabilizer tube in the socket in the rear of the
fuselage. Center the tube in the fuselage.
127. Connect the lead from the elevator servo and extension using
a commercially available fastener. Slide the stabilizer on
the tube. Use a 3mm hex wrench to tighten the screw that
secures the stabilizer to the fuselage.
Î The screw may require loosening to fit the stabilizer.
