The ideal C.G. position is 220mm ( 8.65 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
# 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 designed for high speed flying. Too low an air speed during take off or landing
may cause tip stall. Point the DeltaJet EP towards the wind, use full throttle and let the DeltaJet EP
gain enough ground speed before pulling the elevator gently for take off. For landing, approach against
the wind, maintain power to the ducted fan to keep enough air speed before touch down.
# Make sure the air field is spacious, never fly the plane too close to people and never get too close to a
running propeller.
Extreme caution should be exercised when working with electric powered models.
Make sure the propeller is cleared of all objects, especially your hands before connecting the battery to the
model. Make sure you understand the operation of the ESC (Electronic Speed Control) by studying the
ESC manual. Once you plug in the battery for electric powered model, always treat the propeller as a
rotating one, as accidental movement of the throttle stick will spin the propeller and could cause injuries.
# 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.
Warning!
