OPERATION:
Flight:
Take responsiblity for the safety of yourself and others when flying the X4 !
Do not fly the X4 in crowded places.
Do not fly in bad weather.
Never try to catch the X4 while it is in flight.
This model is intended for experienced pilots age 14+.
Power off the X4 after flight to prevent the propellers from causing injuries.
Always remove the battery after you stop flying to avoid injuries from accidentally powering
on the motors.
Always take great caution to protect yourself when near the propellers. The flight system
will start after powering on regardless of the transmitter signal. The high speed propellers
are very dangerous.
Power off the X4 after every flight, otherwise the propellers may still rotate and cause injury.
Be extremely careful and responsible when using the drone. Small electronic components can
be damaged by crashing or by dropping the X4 into water. To avoid further damages, please
replace broken parts immediately.
