Take-off %62.5 throttle stick problem

Hello Everyone,

I’m building a “big” hexacopter. While lifting in position mode, I saw that the motors were activated when the sticks were powered by 62.5%, and the following phrase was written on the position information page. “TAKEOFF: When landed, the vehicle will take off if the throttle stick is raised above 62.5% percent (of the full range from bottom).”
I want to make sure the engines are running correctly and give the throttle gradually for a controlled take-off. So how can I get rid of this 62.5 thrust level thing? The situation is a bit urgent so I’m asking for your help. I wish everyone a good day.
