I shipped the combo in to tekin for troubleshooting. Just waiting on their results before reporting back. Hopefully it's a easy fix...

My roc is doing the exact same thing....! I thought it was normal as this is the first BL motor I've ever owned...

I will try the things mentioned previously in this thread but if I cannot fix it,
I will call tekin as the motor and esc (RS pro) is less than 3 weeks old...

I have subscribed so I look forward to the results of your new combo.

Excellent support so far Tekin!

It is an anomoly and doesn't affect performance or cause any damage at all. It is sort of a rare occurence, usually just barely moving the rig stops it.

Just an update...

So while I was waiting on the return of the ESC/motor combo, I had switched paces and start working on my scaler build. I went out and got another RS Pro/ROC412 combo and proceed to wire it all up. gave it a good test run and it all worked out very well. I then started tuning it and at the same time, updated the ESC to the latest version. After doing so, I got the same issue, the motor would knock. I just left it as is for now and ignored it.

Fast forward a few days to where got my new RSpro replacement (NIB), went ahead and soldered it all up and installed it back into my R1. Flashed it, and restored the settings. I took it out for about 5 mins, and again, the motor started knocking.

So that's three ESCs in a row with the same issue.

Anyways, I haven't decided on what to do now, I'll probably just live with it, or downgrade to 212 where it is not an issue.
