Throttle set-up
 

Hi, I have a Tactic 650 that I am unable to set the full range of a motor speed controller. I have tried two different controllers so I think it problem is in my set-up.. The issue is that I have a esc beep when the stick is full down at power on, however I have no motor response until I advance the stick to 50%. I have tried no luck using the Throttle Curve (pg 21 of the manual). Any help would be great.
