C.G.

The ideal C.G. position is 117mm (4.6 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.

Important Safety Precautions

Warning!

# 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.
