Wing Joiner
Please dry fit wing joiner into left and right wing to make sure they fit with the
proper dihedral angle, mark the wing joiner if necessary. Apply epoxy glue to
both sides of all surfaces in contact. Use a stick to apply the glue to inner side
of wing joiner sleeve, and apply the glue to wing joiner before putting them
together. Wing joiner not glued properly will lead to wing failure and plane crash.
Apply instant type CA glue to both sides of each hinge.
4.8V - 6.0V operation only, higher voltage
will burn out the retract motor.

3.5 in.
http://www.theworldmodels.com/para/instruction/instructionManuals.php
The ideal C.G. position is 90mm (3.5 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.

P.12
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
adjusted aircraft.
pre -
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.
i
s specially designed to be powered by
2-stroke 0.40-0.46
engine,
using a more powerful engine does not mean better performance. In fact, over powered
engine may
cause severe damage and injuries.
Should you require to bend the landing gear wire, please dismantle the retract assembly from the wings
and use a vise to clamp the wire for bending. Bending the wire directly with the retract still in the wings
will damage the mounting block structure.
