Sinus-8 ESC failure report

Hello, I’m running an old WEMA Sinus-8 ESC on my Plane which has an MATEK F405-WTE onboard.

The problem is that if i power the Plane, the FC takes too long to start up.

The ESC has a failure report if, after getting Voltage on its Power connections, there is no PWM Signal for 10 seconds. After a Failure report it doesn’t react on PWM input, an i can’t turn that function off.

Is there anything that I can do that my FC sends out PWM Signal 1000 within 10 seconds after connectiong to the Battery

There is option to send PWM to motors when disarmed.

Yea, but that longer than 10seconds, so probably the best would be to get a new ESC
