Syma X5C repair – motor replace
Few month ago I crashed my Syma X5C in the backyard and I recovered the quadcopter only after few minutes. Unfortunately, because the motors of the quad didn’t stopped after hitting the ground, the propellers have hooked in 20cm high grass.
After I removed all the grasses around the propellers and motors shafts I tried to fly again with my Syma X5C but two of the motors didn’t start anymore.
Because it is made from lightweight and durable materials, mechanically nothing happened to the quadcopter. In order to found the problem I had to check electrically every component of the Syma X5C separately.
I removed the quadcopter ‘s cover to check if the problem is from some poor quality wire connectors or cold soldering, but I didn’t found any of this. I concluded the aircraft ‘s mainboard or two of the motors died.
To be sure which are the faulty parts I reversed the spinning motors with the “dead” motors. Same thing, two motors are spinning and two are not. That is somehow good news, because only the motors died.
When I removed the dead motors from the Syma X5C I found that one of the motor base was melted because of the motor’s heat.
All quadcopters use two type of motor: clockwise and anti-clockwise. In case of the X5C you can make the differences by the color of the motor wires. The two clockwise motors has blue and red wires and the anti-clockwise motors has white and black wires.
Syma X5C repair. Make this drone fly again.
After I identified all the faulty components I started to look on the internet for cheap spare parts to repair my Syma X5C quadcopter.
In no more than five minutes and I placed my order for two anti-clockwise motors and one motor base. The price was very affordable, only $8 with free shipping.
Shipping could be faster, but after 27 days from placing my order, I had everything I need to replace the faulty parts and repair my Syma X5C quad.
Tools and materials that you need to repair your Syma X5C
- Cutting pliers;
- Soldering iron;
- Tin lead resin for soldering;
- Spare parts to replace the faulty components;
- A lot of patience :)
Firstly I removed all the faulty parts and carefully replaced them with the new ones. Always disconnect the battery to prevent any short-circuit that can damage your quadcopter.
When you are replacing the Syma X5C ‘s motors you need to pay attention to the polarity of the motors.
You have to solder the motor wires to the receiver board in this order:
- Motor M1 (anti-clockwise) – White to M1+ and Black to M1-
- Motor M2 (clockwise) – Red to M2+ and Blue to M2-
- Motor M3 (anti-clockwise) – White to M3+ and Black to M3-
- Motor M4 (clockwise) – Red to M4+ and Blue to M4-
After I soldered back the new motors, I powered ON the quadcopter to see if all the motors spins freely and correctly. Good news, the surgery was a success and the patience is still alive :)
It remained the last stage, reassembly and screwing all the bolts of the aircraft.
After the successful repair, my Syma X5C was ready for the next flight!
