21 Main Wing
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 PM3 x 18mm 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 PA3 x 18mm 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.

The ideal C.G. position is 85mm (3.34in)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
