NOOB servo throw question regarding Gripper

Hello all,

I’m new to RC so please forgive my ignorance here.

I am trying to figure if it is possible to adjust the throw of a servo I am using for Gripper.

I am on Copter 4.04, the radio is a HereLink, the servo Henge MD752 in Tarot’s Dispensers Parabolic Device.

I have been playing around with the ServoX_Max and ServoX_Min as well as the max and min of the RC channel. Regardless of what I set I get full travel.

Am I missing something?

Cheers
