Hi Tobias,

Apologies for the late reply. Things have been busy and I haven't had too much time for this project lately. I did check what you suggested. The blue-yellow did measure 10 kOhms, but was unable to get any resistance between the blue-green.

Thank you!

Hi! I have done extensive testing with a friend who is competent in electronics, and gone through the posts you suggested. The motors all work on their own, but the 4th does not work on the board... I have applied VCC to the 4th motor and that makes it spin. But it seems like on bootup the MOSFET is...

Here's the other side as well:

I really can't see any problems. I could go into work with this and check using the multimeter there. Is there a guide as to which positions I should be checking?

Is this a viable solution? Seems like it could cause problems down the road if you need to have different rpm or whatever for m2 or m4

Hi guys just got done soldering and testing the rotors by turning it on with the battery. M4 doesn't spin... It doesn't look like there are any shorts whatsoever. I dont have a multimeter handy so I can't confirm. I'm pretty frustrated as well -- didn't realize the soldering would be this difficult....
