Hello All,
This is my first post so if I could do something better next time please let me know. I'm having trouble with my Kaideng K70C. It worked great out of the box, even when replacing the stock camera with a Xiaomi Yi Action Camera, which is noticeably heavier than the stock camera.
Eventually the K70 started having trouble staying airborne, and I had to manually pull it back and to the left, as it was naturally drifting to the front and right. After checking the resistance of each of the motors, I noticed that the front right motor had noticeably more resistance and made more noise when spinning than the other three motors. This led me to believe the front right motor had gone bad.
Since this copter is relatively new, I couldn't find any replacement parts for it, but saw that many people said X8C parts could be used in it, so I order these motors. I initially only replaced the one that was causing trouble, and after letting the motor warm up a bit, I took it out for a test flight. For awhile it was working perfectly, with as good a control as it had before the issue.
Then the quadcopter started drifting to the back and left, as if the new motor was more powerful than the others. After awhile I couldn't even get it to take off, so I hypothesized that either the new motor had been broken in and was more powerful than the others, or the back left motor was starting to go bad. Either way my next step was to replace all of the motors with the new motors.
The replacement motors came in two different types, A (black and red wire), and B (red and blue wire). I noticed in the comments of the motors that some people received one motor that was not spinning in the expected direction, and consequently had to solder the two wires in the opposite configuration. I seem to have experienced something similar.
Currently the two type A motors are on the front 2 arms, and they are spinning in the correct (opposite directions). The type B motors are on the back 2 arms, and they are spinning in the incorrect direction, but still spinning in opposite directions. I thought perhaps I could correct this by switching the back two (type B) motors, because if I could get them both to spin in the opposite direction that they were, everything would be correct.
Switching the motors, however, gave me the same result as before. So currently my situation is:
Front Left: Type A motor spinning CW
Front Right: Type A motor spinning CCW
Back Left: Type B motor spinning CW
Back Right: Type B motor spinning CCW
Any help getting this solved would be very much appreciated.
