Product Usage Cautions

When flying, the fast rotating propellers of FlameWheel550 will cause serious damage 

and injury. Therefore, please fly with a high safety consciousness. 

1. Keep flying multi-rotor away from objects, such as obstacles, children, 

human beings, high-voltage lines and so on.

2. Do not get close to or even touch the working motors and propellers, which 

will cause serious injury.

3. Do not over load the multi-rotor.

4. Check whether the propellers and the motors are installed correctly and 

firmly before flight.

5. Make sure the rotation direction of each propeller is correct

6. Check whether all parts of multi-rotor are in good condition before flight. Do 

not fly with old or broken parts.

7. Use DJI parts as much as possible.

If you have any problem you cannot solve during installation, please contact our

Make sure wires will not be cut by frame boards and propellers.  Smooth out the boards edge if necessary.  Please install propellers after autopilot system configuration procedure.  Make sure the rotation direction of propellers are the same as the figure shows. In up figure, arms 12 front of craft, arms 45 are back of craft. See from top, motors on arms 135 rotate counter-clock wise, use propellers 1038; motors on arms 246 rotate clock wise, use propellers 1038R.
