The throttle cut off on my new xf631 does not work for some reason. If I understand it correctly when the button is pressed the throttle should close but it does not. I see the servo move slightly and thats it. Is there something I am missing with the setup maybe?

Thanks in advance

Contact Horizon Hobby's Tech Support.....and have your tx. with you when you do. I bet you have inadvertently set the servo to over 100% throw, so the kil switch doesn't have any % left to move it.

the throttle cut button trim the throttle to -40 for the time you press it. If your engine is trimmed for idle in the low side of the trim it may not remain enough travel to close the carb. you can set the travel higher by travel adjust menu in your transmiter to allow your idle trim to be set higher so the servo travel between idle and -40 will be lenghtened.
hope it help!
