SAFETY in Assembly
During assembly of this aircraft, you will be asked to use sharp knives and hobby adhesives. Please follow all safety
procedures recommended by the manufacturers of the products you use, and always follow these important guidelines:
ALWAYS protect your eyes when working with adhesives, knives, or tools, especially power tools. Safety glasses are the
best way to protect your eyes.
ALWAYS protect your body, especially your hands and fingers when using adhesives, knives, or tools, especially power
tools. Do not cut toward exposed skin with hobby knives. Do not place hobby knives on tables or benches where they
can roll off or be knocked off.
ALWAYS have a first-aid kit handy when working with adhesives, knives, or tools, especially power tools.
ALWAYS keep hobby equipment and supplies out of the reach of children.
IMPORTANT NOTE – We strive to provide the absolute best-quality ARF aircraft on the planet. However, the ultimate
success or failure of this aircraft is dependent upon proper assembly by you. If you have questions about an assembly
step, please contact us, or read the assembly thread for your airplane on RCGroups.com before proceeding. It is always
better to slow down and be sure of your assembly than to rush through it and make a mistake which can cause a crash.
SAFETY in Flying
SAFETY NOTICE: This is NOT a toy! It is a very high-performance RC airplane capable of high speeds and extreme
maneuvers. It should only be operated by a competent pilot in a safe area with proper supervision.
ONLY fly your aircraft in a safe, open area, away from spectators and vehicles–and where it is legal to fly.
NEVER fly near overhead power or utility lines. If your airplane ever becomes stuck in a line or a tree DO NOT attempt to
retrieve it yourself. Contact the authorities for assistance in retrieving your aircraft. Power lines are DANGEROUS and
falls from ladders and trees CAN KILL!

Never run your motor inside a house or building with the propeller attached – Remove the prop for safety.
