Motor 3 not spinning up with transmitter

[applekeith]

This is an odd one. And I am at my wits end... In Beta Flight I can use the program to move all of the motors, nice in sync or individually. If I use the transmitter, motor 3 may get half way compared to the other 3 maxing out at 2000. I have tried multiple versions of betaflight. If I swap motors 3 and 4 on the FC (NAZE32), motor 3 still is not as responsive. I have calibrated the ESCs numerous times (no help). I replaced the PDB. Replaced the FC, and receiver (OrangeTX/RX) as well.

I don't know where to go from here. Everything looks good in betaflight. The receiver/transmitter work like they are supposed to. It is only motor 3.... Like I said, I am at the end of my rope and about ready to chuck it all out. As a side note, I started with cleanflight and it does the same thing there. I would suspect the FC, but not two of them for the same thing. But I do have a third...

Any hints, suggestions, thoughts will be appreciated. I attached some screen caps of the transmitter/rx page and the motors page...

Does it hover and or fly okay? These things can act strangely on the bench with no props on.

You are so correct. I just had not noticed that behavior before. And it has been quite a while since I had even fired up one of these quads...
Thanks for the encouragement. I took it out and it flew ok... Now for some more practice.

Glad to hear you got it to fly These things can definitely be frustrating but flying makes it worth all the effort.

Most definitely. It was only in the back yard, hovering and a little back and forth (I have a small yard), but it was nice....
