In addition to thrust, the propeller applies two moments to the aircraft:
- The torque that tends to roll the aircraft in the direction opposite to the
propeller rotation,
- and the gyroscopic moment.
It should be noted that historically the gyroscopic moment had an incorrect
sign. The correct sign can be obtained by specifying a **version** attribute
higher than 1.0 to the propeller definition
~~~.xml
<propeller name="a_prop" version="1.1">
<!-- propeller definition -->
</propeller>
~~~
For backward compatibility, the absence of the **version** attribute will result
in the gyroscopic moment to be computed with the legacy incorrect sign.
