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.
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 PM 3mm screw, the set up is for future removal of the wing.
