Read this disclaimer carefully before using FlameWheel550. By using this product, you hereby agree to 

this disclaimer and signify that you have read them fully. FlameWheel550 is an excellent multi-rotor. With 

a good autopilot, it will even offer tremendous flight features for low altitude flight working in restricted 

space. Despite the controller of autopilot operates in the safest manner when the main power battery is 

connected, we strongly recommend customers to remove all propellers, use power supply from R/C 

system or flight pack battery, and keep children away during system calibration and parameter setup.

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 that 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

Important

 Please solder ESCs to power pads on bottom board as the figure shows. 

 Use any insulating method at all soldering spots. Make sure there is no short or open circuit. 

 Make sure the side of power pads is upward.

 Make sure the rotation direction of each motor is the same as the way in the figure of 

“Assembly” shows. If not, switch any of two wire connections of the incorrect motor to change 

its rotation direction.

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.  When mounting the propellers, do not use any thread locker, just tighten the nuts to the end manually then use the wrench to tighten it about 50°. 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.
