I recently got a Syma X5C1 2.4g Quadcopter and I am new to all this. It has taken a couple of knocks since I have owned it due to practicing an friends trying it out etc. It worked perfectly fine but suddenly when pulling the throttle up one of the propellors will stop spinning but it alternates as to which prop stops, any ideas as to what this might be, perhaps a new motor is required? Any help or advice is really appreciated. Cheers
You gotta be careful as Syma seems to shake things up. Look on the main PCB and see if the numbers match this one. Syma-X5-R V3 https://goo.gl/V3hiF1 Hopefully you have a good eye and soldering skills. Look for YouTube vids.
