After some weeks of flying and crashing my Syma X11 quadcopter, I decided to change its bent propellers. The stock plastic propellers got bent after hitting hard surfaces, and I have managed to straighten them with my hands and fly again each time. Stability was compromised and I now want to get the original flying stability back.
I bought two sets of Syma X11 propellers from Gearbest (Each set contains four propellers). If this is the first time you’re changing propellers, don’t worry, it’s easy.
Why are propellers of different colours?
Propellers are usually colour-coded. For example, the front of my Syma X11 has black propellers while the back has white propellers. This allows you to easily understand to which side your quad is pointing to, while flying. Additionally, the Syma X11 also uses different LED colours to denote front and back.
Motors do not spin in the same direction
If you look closely at your propellers spinning, you’ll notice that they don’t spin in the same direction. For example, on the Syma X11 – the front left and back right motors spin clockwise while the front right and back left motors spin counterclockwise. Each clockwise and counterclockwise motor needs a different propeller.
You may have noticed that your current propellers are labeled 1, 2, 3 and 4. However, the propellers I’ve received were labeled 1, 2, 2 and 3. Nothing to panic about it, the propellers will work fine if you have one pair of clockwise and one pair of counterclockwise propellers.
Replacing the propellers on the Syma X11
Once that you’ve figured out which propeller goes where, get yourself a small screwdriver and change the propellers! Changing a propeller takes a couple of seconds!
- Hold the propeller and unscrew it from the top and lift it off.
- The second step is to replace the new propeller and screw it back.
- Repeat for other three
Your quad should feel new again now 🙂
