Default center pulse width

I thought I saw it the first time I set it up but cant find it now and cant find any mention of it anywhere. I have a 760/560 tail servo on now and want to drop a 1520/333 in. I did a factory reset but it still never popped up.

Setup->Tailrotor->Output Setup->Frame Rate and select the 333hz setting.

Thats not center pulse width. I need to change center from 760 to 1520 on the tail.

The frequency determines the center pulse width.

I plugged the 1520/333 servo in after setting the frame rate to 333 and it was still at 760, only moved to one side with rudder input or, half travel.

Edit... Possibly I misread the original comment.

Double check Setup->Tailrotor->Output Setup->Frame Rate and make sure the setting is still set to 333hz. Always exit forward programming and wait to see one green flash before powering down to ensure the settings are saved.

My apologies. I read your comment to say that a servos frame rate was determined by its center pulse width and vice versa. Of course that isn't the case. For instance there are both 760/333 and 1520/333 servos.

I believe you were saying setting the FBL frequency is used to set the center pulse width for the controller's programming (which may or may not be the servo's actual value).

Again. My mistake.
