No, just write your own.

Look at http://www.dorbie.com/aqua.html, it has a nice section of motion
models.
Excuse my comments on quaternions.
The principal here is to build an incremental transformation based on
user input and vehicle dynamics and multiply it onto the current
position matrix. You can then extract the new HPR orientation if it's
required. Some normalization and cross products are used to keep the
coordinate frame orthogonal. With this model a translation along the X
axis should correspond to a straffe motion in quake.

Cheers,Angus.
