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, then 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 PM3 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. Ma ke su re th e wing s are resti ng ag ainst the fusel age t ightly. Locate the pre- drille d

2.5mm hole at to p of le ft wi ng, a nd dr ill along w ith 2 .5mm drill bit until it pa sses throu gh the

Note : It is recommended that the wing tube stays with the left wing. Removal of the wings could be

achieved 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 135mm (5.32 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.

# 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.

# is specially designed to be powered by 4c 0.52-0.70 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.

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.
