Throttle pwm output

Hi Guys, I am having a problem with my throttle signal. When I am in the radio calibration tab, my throttle bar moves as normal with pwm values from 985 to 2000 across the full range. But when I am armed and in the servo output tab, my throttle channel bar only moves slightly with pwm values from 1100 to 1180. My motor also does not turn on as I dont think they are receiving a high enough pwm value.

I have calibrated the radio and the esc but it still seems as if it is not outputting enough throttle signal for some reason.

Cheers.

Look for the value of your SERVOx_MAX parameter (where x = the output you connected your motor to).
Or post a .param file with your parameters so we can play detective :wink:

Thanks for the reply, servox_max for the throttle channel looks normal. I have also tried shifting the throttle channel to a different on with the same result.
Here is a .param file. Hopefully you can find something.

What flight mode were you in when you tried it? flight mode 1 and 2 are RTL, maybe that prevented higher output?

You can also set LOG_DISARMED = 1, try again and then upload the log, maybe that gives more clues

And since we are already here:
what FC do you have?
what ESC are you using?

try in manual mode to get full manual control.
