HW Brushless Motor Issue - Too Tight?

[87lc2 2575]

Have a brand new HW V10 G3R 25.5t motor for my F104 and having issues with it.  The motor is very hard to turn when out of the car, and with anything under 1/4 throttle applied the motor just clicks/buzzes and will not move.  With more throttle it moves, but its definitely not smooth.

I verified everything is connected properly (A/B/C wires & sensor cable), so don't think there's an issue there.  Leaning towards a bad motor, but have never had any issues with HW brushless stuff in the past. 

Any input appreciated.  Pretty bummed, have the car all done and was hoping to get it on the track this weekend.

Sounds like motor, if it won’t turn over smoothly with your fingers uninstalled it has issues unfortunately

Yea that's what I'm thinking.  Thank you for the reply.  Now to see about getting a replacement...

Hopefully Hobbywing responds, I placed an email “ticket” for a response when an 10BL120 esc fried as soon as I turned it on 2 yrs ago and i am still waiting for a response lol. I went to my local shop and they exchanged it for me after proving I hooked it up correctly. Support is pretty ******* poor.

Not what I like to hear, haha.   I got it through Amain so contacted them this morning, guess I'll just setup a return.

It was bothering me so messed around a bit this morning to make sure I didnt screw something up.  Swapped sensor wires, swapped ESCs, and even ran this motor on another ESC and this motor is the only issue.   It actually runs better without the sensor wire plugged in so I assume the board is bad.  Took it apart and nothing obviously wrong, bearings good and there's not much else that can go wrong in there.

Can you take it apart?  I had a piece of metal from the manufacturing process inside my brushless.  Very erratic performance. I would run it on the bench, then take it outside and it wouldn't move.  sometimes a lot of heat was produced when not moving.  Once I removed the debris it was fine.

I took it apart and nothing seems out of place, no foreign material in there.  I was really hoping there was, but no such luck.  Even with a bad sensor board I can't see that making it hard to turn when there's no power to it.  I figured there had to be something wrong mechanically but there's not much to these things and it looked just fine on the inside.
