Mecanim robot tutorial Rocketpack?

i put this line to try and turn walking off when the robot is flying, but his is still walking if i go forwards in the air.

         if (Physics.Raycast(ray, out hitInfo))
         {
             // ..if distance to the ground is more than 1.75, use Match Target
             if (hitInfo.distance > 1.75f)
             {
                 
             Quaternion.identity, AvatarTarget.Root, new MatchTargetWeightMask(new Vector3(0, 1, 0), 0), 0.35f, 0.5f);
                 anim.SetBool("Idle", true);
                 anim.SetBool("Locomotion", false);
             
             }
         }
