5.04 in.
http://www.theworldmodels.com/para/instruction/instructionManuals.php
The ideal C.G. position is 128mm (5.04 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.
If you are converting this model to electric, please move the C.G.
forward 5% of current C.G. distance from leading edge to
compensate for weight of fuel.
If you are racing the Strega over 100 mph, move C.G. forward
by 1/2 inch.

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.
is specially designed to be powered by
2-stroke 0.40-0.46 engine
performance. In fact, over powered
engine may cause severe damage and injuries.
or
4-stroke 0.70-0.81 engine, using a more powerful engine does not mean better
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
