RPM seems wrong in Castle log

[dure16]

Anyone know why it shows RPM over 70K? This was a 1550kv motor on 6S, which should be under 40K RPM.

Is the logger set on 2 poles instead of 4 as it's showing close to the double of the expected rpm?

I am not 100% sure,
But maybe the motor Pole is not correct

I beat you to it

Poles are set incorrectly.

In the graph viewer go to edit > change motor pole count / gearing

Only because I literally woke up 1 minute ago. I am a slow fart in the morning here.

Is it a pole thing?

Question:

In the above setting, is that the default Spec. Gear Ratio being 1:1?
Selecting "No Gearing/Direct Drive" would be the same as 1:1??
Wouldn't it???

Affirmative on both questions.
The RPM logging is only somewhat accurate. I never enter any gearing into it. I always leave it on 1:1.

I don't own a CC ESC ...yet.
I really should have one by now. I know.
TY.

Anytime
And yes...you should. If you're doing anything performance oriented, be it drag racing or speed running, the data logging will be an essential puzzle piece to understanding what is going on and optimizing your setup.

Changed the pole count. Thanks guys.

I recently bought my first and the best feature is temperature cutoff. I hate that the XR8 only has two settings for motor temperature limits and they're really high - 221F and 257F if my memory serves me correctly.

With castle, I can choose any of the below cutoff temps. I also have it set to emit an error beep if the sensor cable breaks contact.

So I never have to monitor temps while pushing the car hard. It's great. It's the main selling point for my needs.

Yeah my 3 HW XR8's definitely fall short on features I hunger for.
I need to step up my game a bit here.

Rezus, 221°F is already way too high for my liking as you're already really close to, if not, hitting temperatures damaging to permanent magnets. 257°F isn't even debatable, you're definitely ruining motors with temperatures like that. That's nuts.
