In helicopters, you push the collective to go down and pull to go up.
PageUp is usually used to push, PageDown to pull.

The yasim model has constant rpm. It is the throttle axis ( joystick,
keyboard or mouse ) that is mapped on the collective. If you look at
a 4 axis joystick, you push the lever to go down and pull it to go up.
On a fixed wing aircraft, you push to increase throttle and pull to
decrease.
So here is the rationale for this. If you invert the way the collective
react to input, you will be at the opposite of the real thing.
