Pre-Flight Inspection and Checks
• Make sure all batteries are fully charged.
• Check all propellers are in good condition and correctly fastened. The edges of the propeller blades
must be smooth and undamaged.
• Manually rotate the 4 motors to ensure they can spin smoothly.
• Ensure the sealing surfaces of the cover are clean, free of dirt, sand, or any other contaminants.
• When the drone is flying in the water and landing to replace the battery, please wipe the battery cover
and the surrounding water droplets first. Avoid dripping into the engine compartment when opening
the battery cover and causing damage to the product
Flying Guide
• Many regulations require the pilot to fly a drone within line of sight. Take particular care when flying a
drone out of sight.
• Unless it is an emergency, NEVER Lock or STOP the motors in flight as this will cause the drone to fall
to the ground and crash.
• When the low battery level warning is activated, plan to return the drone and land safely before the
battery reaches a critical level.
