285-3411 FOCUS - Replacement Rotor Blades

4 blades - 2 white front and 2 red rear.

Quick Tips:

- To remove the Rotor Blade grasp the blade with your fingers and slowly and steadily pull up on the blade.  They are very tight, but will slide up and off the motor shaft. 

- White blades and LED lights in the front with red blades and LED lights at the rear. This helps you know which is the front and which is the rear!

-Blades The Right Way
                                

     When all the motors are working together to fly the Drone , motors 1 and 3 spin the drone counter clockwise , while motors 2 and 4 spin the drone clockwise. Altogether they counterbalance each other for stable flight.
   Individually,  motors 1 and 3 should spin clockwise with a clockwise prop, and motors 2 and 4 should spin counter clockwise with a counter clockwise prop.  
  You can tell the direction of the prop, by knowing which is the leading edge. The leading edge always turns forward. The leading edge is always the edge that is twisted upward.

   
    Before flight testing, we needed to ensure the motors were spinning in the correct direction and that props were attached correctly (airflow moves downwards), otherwise the quadcopter will spin out of control!
• To remove the Rotor Blade grasp the blade with your fingers and slowly and steadily pull up on the blade.  They are very tight, but will slide up and off the motor shaft. 
• To reinstall a new Rotor Blade, center the blade over the motor shaft and push it on.  
• White blades and LED lights in the front with red blades and LED lights at the rear. This helps you know which is the front and which is the rear! 
• So, You need two of the same colored blades that  are exactly opposite of each other in there pitch. If you look at them you can see the twist in the blades will each be in a different direction. So you need two opposite pitched white blades, and two opposite pitched red blades.  Put the whites on the front, as in the directions above, and when you put the reds on the back, make sure that the pitch is opposite from the white one in front of it. If the wind from them is blowing down when you run it, then you have it right. If the wind is blowing up.. then switch the blades from side to side, and the wind will be directed down.

• Tip: You may find your rotor blades getting a little loose after removing and putting them back on during maintenance of your Drone. If they refuse to stay on.. Try a little nail polish on the motor shaft.. just a tiny drop, and careful of the motor, don't get any in it. It will act as a friction shim, that should hold the blade on, at least until you get some new ones.
