Firmware, Bad motor, ESC?

Hello, I posted this as a reply to a previous discussion I had, but thought I would start a new one too.

I connected my 3DR Y6 to Mission Planner, hoping to check calibrations, and I noticed the top back motor wasn’t spinning.  I just recently (a couple months ago) replaced that motor because it wouldn't spin.  I did the necessary ESC calibration before replacing it, and it didn't fix anything, so I replaced it.  I did the ESC calibration again, did some test flights, and everything worked well.  I haven't flown for a while since, as the weather has gotten pretty frigid and snowy here. I'm wondering if the ESC has to be calibrated that frequently for the motor to spin?  It just confuses me because I had flown very frequently all summer with no problems with motors not spinning.  The other thing I noticed is there is a firmware update (V3.2). Would a firmware update have anything to do with the motors?  I didn't want to update yet in case anyone had problems with V3.2 so I thought I would check on here?  Any suggestions would help

  • If you are upgrade from 3.1.5 to 3.2 it's a great idea to re-do all of your calibrations - accel, compass, ESC. and radio.

    Also, be sure that you are applying the correct frame type when you're going through your setup.


    • Do you know if I have a Y6B, if I should be selecting ArduCopter V3.2 Tri or ArduCopter V3.2 Y6 for flight version when installing firmware? The Y6 option looks like it has a different motor/propeller setup than mine does.
