Troubleshooting Motor Issues on Micro Toothpick Build
What's up guy? Have a question, I just put together a micro toothpick using the emax nanohawk aio, the aio is confirmed good. Issue is, motors 1&3 spin up fine, but motors 2&4 don't. They get really restricted when I try to give them a little flick when checking it. Like they lock themselves but when I disconnect power they spin smoothly by hand. Is it possible I wired the motors up backwards while the aio is trying to spin the opposite way making them "lock up" when armed? Thanks guys. Happy flying.

1. Check to make sure your motor screws dont touch the motor windings.
2. Check that none of the motor wires are bridged together. If your using the plug check on the other side of the aio where the plugs are soldered to make sure nothing is bridged and everything is conected well.
3. Make sure ground isnt bridged with power anywhere with a multimeter just touch the two battery pads on continuity mode make sure for no beeps ,if you have a capacitor soldered it might beep for a split second then stop thats normal its just it charging up. Also make sure the motor wires do beep try all the combinations on the motors and make sure they beep because the plugs im suspecting your using could be not having good contact on the motors not working.
Also there is no way to solder your motors backwards as they are brushless motors where you can just change the directions in betaflight or whatever FC software being used.

They're direct soldered, no screws touch any windings as well. I have clean solder joints too. I've tried to trouble shoot all possibilities using the net and everything is pointing toward the wires being mixed up and I can't use motor wizard in beta because this little dude is on an older version of betaflight. Thank you for replying my friend I appreciate your help. 👍

also check your settings in betaflight are all correct. Having the wrong motor/esc settings selected can cause this to happen. Especially having the wrong dshot or number of poles. Make sure the motors are properly ordered in betaflight as well and that you've selected at least the default tunes and filters preset. Remember, dont do any of this with props on. This is a tricky part of building, so try not to feel discouraged!

I've tried playing with the dshot numbers and it gets the same result. All of my motor poles are perfect also. I used the stock nanohawk cli dump and the emax motors that go with the nano as well. So it's all on stock tune. I should have mentioned this all started after I installed an elrs receiver in it and the 1 wire on motor 2 came off, re-soldered that, and 2 wires on motor 4 which were reattached as well. I swapped everything onto a toothpick frame, so everything with the quad was fine before that. It flew perfectly normal. Ive tried trouble shooting all possible avenues. That's why I asked if it was possible I crossed the 2 wires on motor 4? I'm unable to use the motor wizard in beta because as you probably know this little guy is on an older version of betaflight. I appreciate you replying and helping me out. I've only been into fpv for a little over a year and just started taking it up a notch and trying to build my own stuff. Thank you my friend I really appreciate your time.

It does sound like thats probably a physical issue with the motors then. They can definitely be temperamental when doing stuff like that. if you want to try digging deeper into configuration before replacing them, try the esc configurator. Also, I might have missed this, but when you go into betaflight or the esc configurator and run the motor test with the battery plugged in, do they start spinning once the throttle is raised at any point?

Also check if in beta flight you have the number of magnets on the motor bell set correctly as i had severe jitters on a whoop build because i had it set wrong and assume it could cause more severe issues aswell.
