WARNING!: Securely glue together, if coming of during flights,
you lose control of your plane which lead to accidents.
Trial fit each part before gluing . Be certain that there are no gaps.
If the parts will join, but with a gaps, sand or trim the parts a little at a time
until the parts meet exactly with no gaps.
Carefully slide the wing halves together, ensuring that they are accurately
aligned, firmly press the two halves together, allowing the excess epoxy run
out. Clean off the excess epoxy.
When joining the wing halves it is extremely important to use plenty of epoxy
(30 minutes epoxy).

With the retract and retract servo in the retracted position,
mark the position where each of the pushrod will attach to

14- HORIZONTAL STABILIZER
Trial fit the horizontal stabilizer in place on the
fuselage. Check the alignment of the horizontal
stabilizer by measuring from a fixed point along
the center line of the fuselage to the leading edge
on each side of the horizontal stabilizer. The
distance must be equal on both sides.
Using the pencil trace around the top and bottom
of the stabilizer where it meets the fuselage.
Remove the horizontal stabilizer from the fuse lage. Remove the covering material from over
both the precut elevator servo and rudder torque
rod holes and from the gluing surfaces on both
the top and bottom of the horizontal stabilizer.

NOTE: Do not glue the horizontal stabilizer into the
fuselage at this time.
Cut two 7/8” (22mm) long slots along
the hinge line in the trailing edge of
the horizontal stabilizer for the two
elevator torque rod bearings. Position
one slot on each side of the horizontal
stabilizer, 1”(25mm) out from the
centerline.
Test-fit the two elevator torque rods
into the slot, marking sure that the
threaded portion of each torque rod is
toward the bottom of the horizontal
stabilizer.
NOTE: You may need to open up the slots so that
the torque rod bearing are not too difficult to push
in
Cut away the covering material from over the
precut elevator torque rod mounting slot in
each elevator half.
Drill a 1/8”(3mm) diameter hole in each torque
rod mounting slot, marking sure that you drill
the hole perpendicular to the leading edge of
the elevator half.
Position each hole 1-3/16” (30mm) out from
the edge of the elevator half.
Thread one nylon adjustable control horn onto the end
of each elevator torque rod, making sure that the
adjustable control horn face forward.
Test-fit one torque rod into each elevator half. Each
torque rod should fit firmly in the precut groove and
the outer surface of the torque rods should be nearly
flush with the leading edge of the elevator halves.
When satisfied with the fit and alignment, remove the
torque rods and set them aside for now.

Slide the horizontal stabilizer partially into the
fuselage, marking sure that the top of the horizontal stabilizer is toward the top of the fuselage.
Apply a thin layer of petroleum jelly to only the
pivot point of the torque rod bearing, then slide
the adjustable control horn through the side of
the fuselage and glue the torque rod bearing
into the slot you cut previously in the horizontal
stabilizer, using a thin layer of 5 minute epoxy.
A
B
After the epoxy sets up. Pull the horizontal stabilizer through the other side of the fuselage and
repeat the previous procedures to glue the second
torque rod wire into the horizontal stabilizer.
Realign the horizontal stabilizer, then glue the
horizontal stabilizer into the fuselage, using a
generous amount of thin CA. Apply thin CA to each
of the four joints and use a generous amount to
ensure to strong bond.
The elevator hinges are preglue into the elevator
halves. Working with one elevator half for now,
apply a thin layer of petroleum jelly to only the
pivot point of the two hinges.
Slide a small piece of waxed paper between the
torque rod and the horizontal stabilizer to prevent
gluing the torque rod solid.
CA
Without using glue yet, push the elevator half and its
hinges into the hinge slots in the trailing edge of the
horizontal stabilizer, marking sure that the torque rod
is firmly seated in the slot in the elevator half. There
should be a minimal hinge gap and the end of the
elevator half should not rub against the horizontal
stabilizer.
When satisfied with the fit and alignment, hinge the
elevator half to the horizontal stabilizer, using 5
minute epoxy. Make sure to apply a thin layer of epoxy
to the top and bottom of both hinges and to the inside
the torque rod mounting slot and to the end of the
torque rod itself. Repeat the previous procedures to
hinge the second elevator half to the other side of the
horizontal stabilizer.

Cut away the covering material from over the precut
rudder hinge and rudder torque rod mounting slot.
Realign the vertical stabilizer , ensure that the vertical
stabilizer is perpendicular to the horizontal stabilizer.
Then glue the vertical stabilizer into the fuselage, using
a generous amount of thin CA. Apply thin CA to each of
the two joints and use a generous amount to ensure to
strong bond.
Apply a thin layer of petroleum
jelly to only the pivot point of the
torque rod bearing.
Glue the rudder torque rod bearing
into the slot you cut previously in
the vertical stabilizer, using a thin
layer of 5 minute epoxy.
19- VERTICAL STABILIZER
20- RUDDER
Without using glue yet, push the rudder and its hinges
into the hinge slots in the trailing edge of the vertical
stabilizer. There should be a minimal hinge gap and the
end of the rudder should not rub against the vertical
stabilizer.
When satisfied with the alignment, mark the mounting
hole position, where the rudder torque rod meets the
rudder with a pencil.
Remove the rudder and drill a 1/8”(3mm) diameter
hole in torque rod mounting slot, making sure that you
drill the hole perpendicular to the leading edge of the
rudder.

BEFORE FLYING CHECK EVERYTHING
Before each flight, inspect the airplane for any loose parts. Check the hinges, make sure the pushrods are still firmly
attached, and check the engine mounting bolts. In general, check everything on the plane that might possibly come loose.
CHECK THE FREQUENCE BEFORE FLYING
DO NOT FLY NEAR A POWER LINE
The power lines cause radio interference, so avoid flying near them.
Adjust the engine always from behind, but never from infront or the sides as rotating propeller may badly injure you!
Do not allow watching people to get too close to a rotating propeller.
Ensure the spinner and propeller are securely attached. Immediately disure defective propeller as well as deformed
spinners.
Warning!
IMPORTANT:
Please do not clean your model with pure alcohol, only use liquid soap with water or use glasscleaner to clean on surface of your model to keep the colour not fade.
