# 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 2C 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.
# 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.
