Hi guys,

I have already read the manual which says that I need to protect the wiring by adding a ferrite, which I did already.

The esc is castle 120hv and I am using a spirit pro. The model is a goblin 570. What Can I do for fix that?
Also..I f I should fly with that error, will cause a crash during the flight or it doesn't affect it? I am scared to fly in this condition.

p.s. sensor filter is already set to 8.
thank you

Hi,

the problem could be caused by too high value of the Governor Response.
Could you try to decrease it in the Governor settings?

It depends on if you were changing the value in some way from default configuration.
But you can try to set it to value of 4.

Hi Thomas,

my value was 5 and I decreased it to 4. nothing seems changed though. Any other suddgestion?
here is the logImage

Also...I have noticed that request rpm are a little bit different from current rpm, especially in idle up 1.

IDLE1: request 2072, current 2300
IDLE2:request 2300, current 2400
IDLE3: request 2600, current 2600

thank you!

Hello,

you should never use higher frequency for Castle ESC than 60Hz.
This can cause big troubles.

Are you using Castle ESC Telemetry?

Throttle frequency
To achieve the fastest governor reaction it is necessary to set the highest possible frequency. For ESC it could be only 60Hz, but mostly all can work even with 200Hz. If you are unsure, please contact manufacturer of the ESC. For combustion helicopters it is max. operating frequency of the throttle servo.



That’s why I put 200..
