Properly calling a Logitech Attack 3 Joystick Class

The documentation for the Joystick::SetAxisChannel() method suggests otherwise.

Last I "wrote" a custom class, I took gyro.cpp/.h source, renamed the files gyro48.cpp/.h, and changed the code to permit adjustment of the sensitivity parameter, which was previously not exposed to the end user.

If you were adding an interface to a private attribute of the class, then the way you did it was probably necessary. But was there ever a version of the Gyro class that didn't have the SetSensitivity() method?

Seemed easier and more likely to work to adapt existing code than figure out all the BS of inheritance and writing my own classes and worrying about missing some inane piece of required syntax that would break the code or worse, compile it and cause unintended results I am not equipped to debug. If this somehow violates some code of appropriateness seasoned programmers adhere to, well, I'm not a seasoned programmer, nor do I aspire to be, so I guess it doesn't matter.

Since you seem to think subclassing by way of inheritance is complicated, I suspect you don't know what it means. It is not complicated. It should be as easy as

public class Axis_3 extends Joystick {
  float Axis_3::GetThrottle()
  {
	return GetRawAxis(2);
  }
}

That's kind of crude, but it should be effective. Note that I don't use C++ enough to be confident that I've done it correctly. Perhaps someone else with more experience and expertise can chime in and either confirm or correct my code.

In the case of the joystick class, I'd simply change the default throttle axis from 3 to 2. Bing bang zoom. But with GetZ or GetRawAxis in the default class, I don't need to do that, so I won't even bother.

With the existence of SetAxisChannel(), I think you can indeed change the throttle axis of any Joystick object from 3 to 2 without even creating a new class.
