Hubsan X4 Circuit Board Problem?

Hi, I'm new on this forum. Hopefully this is the right place for this post..

I am having an issue with my X4. The left side motors are inoperative. I had to do a little soldering to replace a motor with a bent shaft and a replaced a broken shell. I have not soldered in some time so it is possible that I messed up the board. But, before I replace the circuit board I am wondering if there is anything I should try first. The right side motors spin and have a voltage drop of about 3.5. From what I can tell there is no voltage to either left side motor. I have tried calibrating the transmitter to the quad. I have also tried tilting the drone while the throttle is at full. None of the above make any difference. At this point the M2 motor has a broken positive wire from all of this moving around, but regardless there isn't any voltage at the M2 or M4 terminals.

If I do need a circuit board where can I purchase one for a Hubsan X4 H107C HD?

Thanks!

Hi mate I had the same thing on an older hubsan x4 , banggood.com is not bad for this item , but it may be worth getting a BNF and use the one you have now for back up parts
if I zoom the photo it looks like there is a hole in the board and looks as if the plus lead on m2 is going to the LED pole I may be wrong its hard to see, these boards are hard to solder your need a very fine tip and not too hot
 
Yes, it does look like a hole. It isn't. Rather, I think the solder came loose from the pad for the M2 positive lead (which also shares power with the camera). I actually already bought another Husban X4 thinking I might use this one as a backup or for more risky flights. Or if I cannot get it fixed it will be for parts like you said. I will look on banggood. What is BNF?
Thanks
