Antenna Tracker Scan Speed?

Can anyone give me some insight on increasing the Scan Speed for the pan Servo on Antenna Tracker 1.1?

Ground Station:
-MP: Latest Firmware
-AT:1.1 Firmware on Pix32 FC Clone w GPS
-Telem: Sik 900 to vehicle.
-Runs Auto or with MP on PC via USB
-Working well overall. No issues other than slow speed in scan mode.

-Custom Wing
-PX4 Mini FC, latest firmware
-QGC, latest firmware
-Telem: SiK 900 to ground station FC running Ardu Antenna Tracker 1.1
