Hi
I was wondering if there was a way to control the pan and tilt speed when using the joystick on the extension rod

Hi, thanks for the inquiry. Upon check the Extension rod manuals it seems that the movement can't be increased. However, I'd like to check the situation with our department for further clarification. Thank you for your support.

.....what is this control stick calibration?

The more you move the control joystick, the faster the pan / tilt movement.  There's no other adjustment.  I posted a video showing the extremes of speed in another thread a while back.  Which one?  Sorry, I can't remember!  But it goes from a very slow crawl up to the full speed of the gimbal.
