The course and headings settings are uncontrollable. Tune a VOR and try to set the course on the HSI and the indicator keeps rotating and will not lock onto a course to the VOR. Same  problem with heading settings .

Try shorter taps on the mouse button.

It seems if you hold down too long on the mouse button the knob does take off and spin fast.

I use a few clicks on the mouse to move either knob to where I want it to be rather than a longer hold on the rodent button.

Try that and see if it works better.

Here is what I found out about the heading and course knobs in the 727.

When trying to change the heading or course knobs while the plane is in  motion, your mouse pointer loses focus on the actual knob, and this causes it to spin out of control. If you can keep the mouse over the knob, which can be hard if you are in turbulence, it will work fine.

Just for an experiment. While you are on the ground and stationary, click on one of the knobs to change the course/heading and drag your mouse away from the knob. As soon as the mouse gets away from its focus on the knob, it will just continue to spin and you can't stop it until you place the mouse pointer over the knob again.

This same thing happens to many of the knobs in my other CS aircraft with the exception of the 707 and B-52.

...And as Mark says use small taps on the mouse...Stay away from the wheel if you have a wheel on your mouse...That will only result int eh pointer /Heading or Course to keep going until you tap the key again...
Experiment while on the ground...I found out the hard way :o
