Thank you! I used you alternative method and m4 is spinning again, sorry again for late response.

Thank you, I soldered the contacts using your alternative method, and it works great. Little bit hard to fly but it works!
Quick question, Is it normal for the crazyflie to trust forward as soon as it takes off?

Motor 4 is currently not soldered to the pads. The other motors has about 2,3 ohm in resistance. M4 has 1,7 in resistances but again, the motor is not connected.

Sorry for a really late replay (vacation and stuff), But no I did not manage to solve the issue. I did try to use a multi-meter to measure and see if there is a short between the two contacts, and there dose NOT seem to be. Is there anywhere else I could measure to check for problems?

I have tried using some desoldering braid to clean it up. But to me there doesn't seem to be a short there, the picture might throw you off a bit. I'll try to clean some more nonetheless.

Hi So I've had the Crazyflie for a couple of weeks now, and I have still not been able to fly it yet. When I first got mine, I managed to solder M4 the wrong way, No problem I'll just de-solder it. Well I did and it didn't go so well. When I finally managed to solder M4 back the right way, I noticed...

Thanks! turns out a small piece of solder was shorting out one component.. I am able to connect to the crazyradio and charge it now.
Anyway, looks like m4 aren't getting and voltage, so i'll have to do some more troubleshooting before I am able to fly, Thanks again

So i just finished soldering and the crazyflie cant seem to pass the start up phase (motors not spinning), before i started soldering everything worked fine, i even updated the firmware without and problems. When I connect it to the computer with a micro usb cable the blue LED turns on, but when i h...
