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 HM3 x 30mm
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 HM3 x 30mm 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 PA3 x 30mm 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.
# 1/4 Clipped Wing Cub is specially designed to be powered by 2C 0.91 or 4C 1.20 - 1.60
engine, using a morepowerful 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.
Don,t use hot iron near the seams or edges,hot iron will melt the glue and shrink the
covering at the same time,causing the seams to pull away.
# Check and re-tighten up all factory assembled screws, use thread locker if necessary.
C.G.26
The ideal C.G. position is 112mm (4.41 in) behind
the leading edge measured at where 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.
Warning!
