Step 1. Insert the aluminum wing tube with the pre-drilled hole end into the right wing. Align
the lines marked at the wing root and wing tube and apply the PM3x30mm machine screw
through the pre-drilled hole on top of the wing. ( please confirm the alignment of the hole by
putting a 2.5mm diameter rod through the pre-drilled wing hole before applying the screw )
The hole on the wing tube is pre-threaded, do not over tighten the PM3mm screw, the set up
is for future removal of the wing.
Step 2. Install the right wing to the fuselage by inserting the wing tube (now
attached to the right wing) through the fuselage, then install the left wing.
Step 3. Make sure the wings are resting against the fuselage tightly. Locate the pre-drilled
2.5mm hole at top of left wing, and drill along with 2.5mm drill bit until it passes through
the wing tube. Apply the PA3x30mm self-tapping screw.
Note : It is recommended that the wing tube stays with the left wing. Removal of the wings
could be acheived by removing the right wing machine screw, the right wing then the left
wing with wing tube. If removal of wing tube from left wing is also required, it is recommended
that instead of applying self-tapping screw in step 3, you pre-tap with M3 thread cutter and
apply M3 machine screw.

Important Safety Precautions
# First time flyer should never fly by himself / herself. Assistance from experienced flyer is
absolutely necessary.
# Pre-flight adjustment must be done before flying, it is very dangerous to fly a badly
pre-adjusted aircraft.
# 1/3 CLIPPED WING CUB is specially designed to be powered by 80c.c.gasoline engine,
using a more powerful engine does not mean better performance. In fact, over powered
engine may cause severe damage and injuries.
# Make sure the air field is spacious, never fly the plane too close to people and never get
too close to a running propeller.
# If you find wrinkles on the covering as a result of weather changes, you can use hot iron
to remove the wrinkles. Please begin with lower temperature setting and gradually raise
the temperature until the wrinkles are gone. Too hot an iron may damage the covering.
# Check and re-tighten up all factory assembled screws, use thread locker if applicable.
23 Control Throws Adjust the control throws as shown in
the diagram. These throws are good for
general flying. You can adjust according
to your personal preference.

the wing meets the fuselage. In order to obtain the C.G.specified,add weight to the
fuselage or move the battery position. Check the C.G. before flying.
